Server baremetal KVM hypervisor on USB stick

A while ago I set up a micro-lab using vmware's ESXi (3.5) as per this blog post:
http://www.techhead.co.uk/installing-vm … -quad-core
Is anyone doing something similar using a KVM hypervisor and could share a quick how-to / summary of what they did to get that working?

Yeah, ProxMox is the kind of thing I was thinking of.
As it happens I've made some good progress...
I followed the guide for installing Arch on to a usb stick, thank you wiki! Booted the HP server with a live CD and installed to the 1GB usb stick directly, what was pleasing was the ability to say bye to FAT32 and install boot as ext2 and / as ext4, skipped swap for now based on various comments about it not being necessary for a hypervisor (anyone beg to differ?).  The image on the key ended up being quite large i.e. 890MB so I'll need to look at trimming that back if I keep with the 1GB usb stick though as I want to venture further into tuning the kernel for the hypervisor role I've ordered a 8GB stick so I've got enough space on the stick to compile some custom kernels for testing, will look at optimising the image later though with 8GB the need is much less pressing.
I booted the HP server from the USB key and proceeded to configure for KVM and installed consolekit package in order to get and use pam_ck_connector.so as recommended in wiki. Installed libvirt daemon to help with remote management. Then set up the local hard disk for LVM and created an ext4 partition there which I mounted in /home/vm.
Using libvirt with virt-manager GUI locally made it painless to remotely test the instance is running, using same tool I then defined the vm storage area as /home/vm.
Next step was to download an appliance (google appengine both for testing and some hacking I'm doing on that for a project). I copied that from desktop to the remote server and followed this guide to extract and convert the vmware image to a raw qemu image - all I did was get as far as the convert step, then I just used virt-manager to import the image and followed the prompts after which the image booted fine and I selected DHCP for network configuration.
Thereafter I was able to access my appliance via HTTP and SSH, everything is running fine :-)
I still need to tidy up the ability to use virtual networks, for now I'm being lazy and just allowing vms to get on the local lan via DHCP assignment from the router (dd-wrt) which is fine for what I'm doing in the home-lab. I can now say goodbye to ESXi and ensure I continue to champion using open source software where ever possible - gotta eat your own dog food! Excluding time I put in to read up and check all sorts of stuff I'd say you can get this done in about 90 minutes or less.
Next step will be to play around with vm migrations back and forth from remote server to desktop though I'll leave that for another day.

  • Installing Snow Leopard Server From a USB Sticki

    In my job, I install Snow Leopard and Snow Leopard Server three or four times a day.
    With Snow Leopard, I've found it easiest to install from a USB stick. So, I did a restore from a DVD to a USB in Disk Utility and it's worked great.
    With Snow Leopard Server, it is not so simple. When trying to install from a USB stick, I get "Mac OS X 10.6 Server Cannot Be Installed To This Machine." Though strangely, installing from the DVD is no problem.
    I've tried to restore straight from the DVD to the USB. I've also tried to install from the DVD to a disk image to the USB. Both times, the USB will mount fine, but I get that error message.
    Am I missing a trick here?

    Oddly enough it is working for me. I had some issues initially so I went out and bought ONE 16GB thumb-drive (major vendor) and partitioned into two partitions.
    I restored one of the partitions with 10.6 and restored the other with 10.6 server. Works flawlessly for me though I do like netinstall. It is a bit slower than the FW800 drive though I do not have to carry around a power brick.
    I hope this helps!

  • Making a Windows 7 Installation USB Stick

    This is a discussion of making a bootable Windows 7 Installation USB-stick Media. It might apply to making other USB connected "Disks" like Smartcards bootable too.
    I recently had to do this (a Laptop with no build-in DVD drive and no USB DVD drive around). And it turned out to be surprisingly simple, using nothing but build in Windows tools from the Disk. I only found
    this german langauge guide and nothing in english (but I might just have searched after the wrong terms, google has been wierd regarding langauge lately), so I thought I write it up (along with some problems I ran into).
    Making a USB-Stick into a bootable Windows 7 (and propably Vista) Media is a 3 step process:
    1. Create a Active, Primary, FAT32 Partition of 4+ GB on the stick
    2. use bootsect.exe from Windows Disk to create the MBR and Partition Boot Record for that Partition
    3. Copy all files from the Disk to said Partition
    4. Test if it boots
    Detail analysis:
    Step 1 is so simple I doubt it needs explanations. Create enough free space on the USB disk (at worst delete all previous Partitions). Make a Priamry Partition of 4+ GiB. Mark it as Active. Format it in FAT32. The Guide used Diskpart,
    but this step can be done with any Partition Tool under any Windows, Linux, UNIX or DOS.
    While the choice of FAT32 seems a bit outdated, theye propably did not gave the relevant bootlaoder the ability to read NTFS. Or maybe they just though FAT32 is enough for a media that is mostly read. I have not tried what happens if I format it in NTFS, but
    it might be possible.
    Step 2 was the only tricky part. You need the programm "boot\bootsect.exe" from the Installation Media. It also must be run on a non-UEFI booted OS (otherwise it cancels out).
    I had a Windows 8 on a new Laptop so I had a UEFI booted system. Luckily I also had a VMWare Windows 7 lying around. I just assigned the Windows 7 ISO image to the Windows 7 VM, then connected the USB drive to the host.
    Once you have the USB stick in a a proper Windows mount the Parttion you created under 1 under any driveletter (should happen automatically under Windows), and open a console as Administrator (asumes DVD is drivletter is D: and the USB stick's partition
    ins Driveletter E:):
    //Go into the boot directory on the Install DVD
    D:
    cd boot
    //You should see a command promt like "D:\BOOT>"
    //Run bootsect.exe
    bootsect.exe /nt60 d:
    Step 3 is to either copy the contents of the DVD media (copy and paste) or the Image (Mount into Virtual DVD Drive and copy/paste, unpack ISO images contents) into the partition.
    How does this compare to other Distribution ways?
    To DVD:
    There is no need for a DVD drive. Even if a bootable USB-DVD drive is avalible, the Stick or Card will only need only USB port (most USB drives need 2 Ports due the 1 Ampere energy need of the drives).
    Flash Media has no seek times and much better throughput (the old weakpoint of any Disk and DVD/CD in particular)
    A FAT32 partition is inherently writeable. So modifications to the "Installation media" like Implementing Service Packs and other Windwos Updates, Modifying ei.cfg/preactivation/setup answer files, implementing special Disk/RAID drivers into the Windows
    PE or adding stuff that should be installed with Windows is easy (and do not requrie reburning a 4 GiB Image file).
    Since it only needs a 4 GiB partition, on a big USB stick there would still be place for other Data Partitions
    Since it relies on old techniques (Generic Bootloader + Active Primary Partition + partition boot loader), multiple Installation media on a big enough stick might be feasible (with a more advanced bootloader like GRUB). Have to test that part.
    However, the cost/media is a lot higher then a DVD. So if you need multiple Medias it will propably be cheaper to use the old DVD approach.
    Due to the needs of bootsec.exe, first creating the media can be more difficulty then just burning an image. But once it is bootable this programm is no longer needed.
    To PXE/network Distrubution:
    If you have the nessesary setup already (DHCP/PXE Server, powerfull network), the USB stick is likely inferior. The USB stick should beat a 100 MBIT Network easily, but will propably be beaten by a 1 GBIT Network. Network isntallation uses existing infrastructure
    (that you need for other reasons anyway) so the cost per media is even lower then the DVD.
    The PXE way also has even better modifyability - sending out different answer files or even automatically booting different images based on the Compuers MAC adress are tried techniques.
    If you lack the nessesary setup, the USB stick is a lot easier to implement and a lot easier to transport.
    Advanced things:
    Need to check if the partition could be formated as NTFS. I prefer a Journalling Filesystem for my USB-sticks.
    Need to check if using a advanced boot manager techniques (like Grub or modifciations to the BCD of the Windows PE) allows me to put multiple install media on one Stick (with one primary partition per "media"). Especially combining the x32/x86 and
    x64 Windows Installation Media would be worthwhile. As would be inlcuding a Window 8 or Vista installation media.
    Current Step 3 and 2 can propably be switched. I see no reason bootsect could not run from the USB stick as it runs from the DVD (it only accesses the MBR and
    VBR of the Disk, areas not in use by Windows)
    Steps 1 through 3 might be possible from the Windows PE environment. If so, only a computer with legacy BIOS boot would be nessesary (no actuall installation).
    Windows 7 can be installed on a (U)EFI system, but I have not checked if I can use the boot from teh stick on such a Computer. Latest for Windows 8 Media UEFI compatibilty is nessesary.
    Let's talk about MVVM: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/b1a8bf14-4acd-4d77-9df8-bdb95b02dbe2 Please mark post as helpfull and answers respectively.

    I converted the stick to NTFS using the convert.exe and it continued booting. So chances are high they only choose FAT32 in the example because no feature of NTFS was per nessesary in a "almost only reading" scenario like installation media.
    The second part depends on the BIOS. I have a more advanced one where I can choose legacy boot options (like USB stick) in the boot option menu even when the default setting is UEFI, as long as I don't need Secure boot (wich I do not).
    Another question arose: Windows 7 has the Kernel/BCD level ability to boot from .VHD Files. The only thing preventing version below corporate from using this feature is a license check that is run just before the login (so way after the booting has been
    completed).
    Starting with 3.0 Windows PE is based on the kernel of Windows 7. So the instlaltion system might have the ability to boot from .VHD too and might have no such check in place. If so, I could put both versions of the Windows 7 installer into .VHD, reducing the
    need to have physical primary partitions for those.
    Windows bootprocess vs. Linux boot process under BIOS:
    The BIOS goes over all the boot media. If it finds one with a MBR, that one is executed and the BIOS part of the boot process is officially over.
     -> Under Windows the MBR contains the "generic boot loader". A simple piece of code as old as BIOS (25 Years) that looks for the primary partition with "Active" Flag on "it's" disk. If it finds one, the Partition Boot Record of that parition is executed.
    The MBR has done it's part
        -> NTLDR (NT too 2000), this one reads the boot.ini file and gives/executeds apropirate options
        -> BOOTMGR (Vista, 7), this one reads the BCD files
          -> Since Windows 7 BOOTMGR can also chainload the Partition Boot Record that is inside a .VHD File
        -> Wicher was used in Windows 3.X/95/98/ME
    Higher versions can chainload lower versions, but must be designed for this and (re)installed in the proper "order".
    The sometimes odd behavior that Windows 7 tries to keep 100 MiB in a seperate primary partition is there to have proper places for later additions to the BOOTMGR settings. Specifically it allows multiple BOOTMGR OS to use/edit the same BOOTMGR instace without
    running into problems with "whose partition is active?" (since it is always the System Reserved one). It's not disimilar to having an extra /boot partition in Linux or how a GRUB's stage 2 works.
    -> Under a typical Grub Legacy the MBR contains the Stage 1. It directly reads the Stage 2 from the proper partition/file system with a hardcoded path, but due to size limit of the MBR cannot do more. In some cases it starts a stage 1.5 wich has more
    space to do work (63 sectors between MBR and first partition), but I never used this Setup
        -> Stage 2 loads the Grub Configuration from the disk. From here it depends on what OS you want to boot.
            -> For Linux or Unix the kernel is started directly.
            -> Any Windows OS up to 7 can be booted using the chainloader command. For the OS this is identical to having the partition choosen by the Generic Bootloader.
    While it can be chainloaded by the Generic Bootloader from the active primary partition, GRUB and thus Linux has no
    requirement for any Primary Partitions. Stage 1 is designed to directly access the specific File System containng the Stage 2. In fact it does not even need to reside on the same disk (as the Generic Bootloader has to).
    If one does not need the Active Flag to control the Generic Bootloader (because a proper Stage 1 is installed in MBR) it is adviseable to mark wichever Windows Partition is chainloaded as active (up to Vista at least I had very odd behavior if the Windows boot
    partition was not marked active, down to randomly shredded Partition boot managers).
    After running a Windows Setup usually the Stage 1 has to be restored, as Windwos Setup will always write it's Generic Bootloader in the MBR. In order to get "rid" of a Grub all one has to do is overwrite the MBR with the Generic Bootloader and set the active
    flag properly.

  • Think M72e start windows 7 with usb stick inserted

    I know in the scheme of things my M72e annoyance is pretty minor,but I am more curious than exasperated.
    If I try to start the machine with a usb stick in any of the ports it won't boot into windows 7and I get a "No bootable partition in table" message and the machine just hangs there.
    If I remove the usb stick and restart, it boots to windows 7 fine.
    Obviously, i figured that the machine is trying to boot off the usb stick before the harddrive. So I went into the bios but there is no option to boot off the hardrive first.
    I can press F12 and it gives me a one time option to boot off the hardrive but I don't want to have to do this everytime.
    Anybody know why Lenovo in its wisdom hobbled the boot choices in the bios?
    Thanks,

  • USB stick won't mount on mac mini, it works perfectly on my macbook

    Both of them are osx lion.
    On the mini the led of the 256Mb USB stick (and still plenty of space!) gives short flashes every second, and won't mount on my desktop, in finder. It doesn't show up in disk utility.
    The mac mini is the most recent server model. I tried USB ports on the back of the mac mini, and also on the connected thunderbolt display. Other memorysticks work well. Only this particular one doesn't work on the mini.
    The memorystick works perfectly in my 2008 macbook pro. Plug it in, it mounts as it should do.
    What can i do?

    In Disk Utility, once you highlight a Drive or Partition, you'll see Verify Disk, (blue arrow), & if a drive you're not booted from then Repair Drive, (red arrow), will be an option also...
    I'm thinking you may have to copy everything off it & see if you can Format it FAT32.

  • Installing Solaris Express 11 on a USB stick

    Hi,
    I am in the process of building a resilient development/testing lab server using 4 SATA disks in a RAIDZ configuration, I want to boot the host SE 11 o/s off a internal USB stick to manage this server, so my question is how do I go about installing SE 11 on a USB stick (persistent not a live image).
    Perhaps naively I assumed this would be easy, as Solaris would just see the flash storage as any other storage. What I have attempted is running the live CD, it detected my USB stick and I continued to run through the installer, I choose a "Entire Disk" install, it took an absolute age in doing this, in the process of installing a message/error appeared about the zpool (sorry I should of noted it), but it continued, once complete, I changed the bios option to boot from USB, this resulted in booting what looked like a successful install, but it just sat at the Oracle progress screen about 20 minutes, the one prior to loading the GNOME login page.
    I've googled this to no avail, I'm having a hard time in believing nobody has ever tried this before, perhaps for good reason that I seem to be unaware of.
    Any help would be greatly appreciated.
    Best Regards,
    Jana

    There are varieties of methods and ways, options i.e.
    1.) From Microsoft Windows (NT i.e. XP (5.x), 6 (Vista) & 7) with the "Open Solaris Live USB creator"; this reported works! Easily and quickly with a graphical user interface transferring *.usb and or *.iso files upon flash drives and memory cards bootably, 'select device / drive and file and click start ; from http://devzone.sites.pid0.org/OpenSolaris/opensolaris-liveusb-creator
    2.) With 'usbcopy' under Solaris 11 / Open Solaris and or the 'installgrub' command.; from http://www.milax.org/files/
    For an example, from within (Open) Solaris a command statement (without the quotes) such as;
    In these 'device' is substitute for the actual special device (file) assigned to the usb flash drive, again as an example if it were assigned "c0t2d0s3" and or "/dev/rdsk/c0t2d0s3"; its device "/dev/rdsk/c0t2d0 with two additional, 2 place fields denotating specifics, such as 's3' for a slice or 'p0' the entire flash device for example purpose, partitioning
    #> "fdisk -d /dev/rdsk/'device'" however to partition, and leave space for other partitions
    or
    #> "fdisk -d -B /dev/rdsk/'device'" for a partition using the entire space available;
    then
    #> "dd if=sol-11-exp--live-x86.usb of=/dev/rdsk/'device bs=512" for example to copy the Solaris 'image' to the flash drive
    and then finally, finishing it, installing the grub boot loader, to boot and or 'start' from. i.e. load and initialize (executing) the operating system, would be;
    #> "installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/'device'" would install grub to the 'device' for 'booting', having it startable ; and or plainly "installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t2d0s3"
    Hopelly helpfull, GOD willing.

  • General question - deploying via drac/iLO vs. USB stick inconsistencies

    This is going to be kind of a general question and see if anyone has experienced something similar and if there is a better way to go about this.
    I have the need to send a Windows 2008 r2 image to a new data center via USB stick.  I built my task sequence and created an ISO from it and mounted it in virtual media in an HP iLO session and built a physical server to test the task sequence.  This
    was just a test to see if the build was good.  It was.
    So I used an ISO to USB tool to put the ISO on USB stick to make it bootable media.  I built the same server via the USB device.  The build got 90% of the way through and during one of the last reboots, it comes up to "Preparing your computer
    for first time use" and immediately reboots itself.
    I have had this experience before where building via a USB stick gives me different results than deploying the same ISO via iLO/drac.  Any clue why that might be?  It's very frustrating and I can't pinpoint any differences.

    I don't know exactly what happened, but a couple of observations based on your description:
    - Are you using bootable media or stand-alone media? If bootable, non task sequence info whatsoever is but on the media. If stand-alone, why are you using stand-alone instead of bootable?
    - Why not directly build the media on a USB device using the console instead of converting the ISO? There are inconsistencies with this at best because of drive letter changes that the media takes into account.

  • USB Stick Won't Appear on Desktop or Disk Utilities

    Hi there,
    One of my USB sticks doesn't seem to appear on my iMac. I have looked in disk utility and it doesn't appear there so I can't format it, and I have plugged it into another Mac and have had the same issue.
    My external hard drive still appears and continues to back up using time machine, and I have tried the other USB ports in case one was faulty.
    Has anyone come across this? Any tips?
    Thanks a lot.

    I have plugged it into another Mac and have had the same issue.
    It is possible the stick has failed since you are having problems on 2 computers and not getting the correct response from what arthur suggested.

  • 1,1 running Lion with XP Boot (re-install and what should i use for recovery disk or usb stick)?

    i am trying to give my 1,1 mac pro a little love and would like to keep this machine running lion. i also have a boot camp installation of XP on it.
    1. can anyone give me instructions on how/whether i can basically do a fresh install of Lion on this machine and minimize the system so it is not cluttered up with all my previous software etc, etc while still maintaining the original XP boot camp partition which i really need to have?
    2. can anyone clarify for me what i should have on hand /if/ i need to boot into recovery mode or some other safe boot mode? i recently ran into an issue where i may have had to use the old Disk Utility format function and there was a reference to booting using the DVD install disks. however i am really confused as to what i should have on hand. ALSO the last time i had to do something on this machine i was told to boot into the Recovery Partition and it appears for some reason (perhaps because i had a "non-standard" windows 7 boot camp installation on the drive at the time??) that there was no recovery partition created when i upgraded to Lion.
    - /anyway/ i am finding that i have the two ORIGINAL install disks for the mac pro on hand, a Max OS X Leopard and a mac OS X Snow Leopard DVD on hand but i am thinking that i should be creating some kind of USB stick similar to the one i created with yosemite? actually, i am not even sure what this USB stick for yosemite is for but i guess i can use it to boot into safe mode or something?
    THANKS for any help as i'd like to get this business under control a little better in case i have an issue.
    i'd also like to install Lion so that there is a Recovery Partition if possible and i think this may be possible if i don't have the windows 7 partition in the machine when i do a fresh install. any help would be great. thanks.

    You have to go out of your way to build the Installer Disk yourself. But this tool makes it easy, and this site contains instructions:
    http://diskmakerx.com
    the bootable installer is basically to re-install the OS if i have to
    Yes.
    the recovery partition is somehow for fixing a problem
    Recovery can go and get you the software and re-download it and start the Install, and allows the use of Disk Utility and can reset passwords.
    or is there some overlap?
    Yes. Both give you access to the Utilities that used to be on the Installer DVD. Disk Utility to Repair or initialize and a few other tools that can allow you to set up to install on an otherwise-bare disk or change your password.
    is "Safe Mode" something completely different
    Safe Mode is a way to start the fully-Installed Operating System in a special way. It first does one pass of Disk Utility (Repair Disk) against the Boot Drive. [Normally this would require booting from a different drive to make repairs.] Then it loads a minimal set of Apple-only kernel extensions, and uses a one-size-fits-all screen resolution. Then it demands your Username and password to proceed.
    From there you can fix settings, use the Finder to add or delete things, and check operation with minimal extensions versus all your daily-use extensions. Very helpful for debugging extension conflicts and graphics settings problems, and fixing damaged settings. The next Restart builds a new extensions cache.

  • Can I install Windows 8.1 as Bootcamp partition from OSX Mountain Lion using a USB stick?

    I have the following:
    Bootable USB stick with Windows 8.1 - 64 bit
    MacBook Pro with Mountain Lion 10.8.5 - it's probably 3-4 years old.
    The Bootcamp partition currently has Windows 7 installed.
    I want to know whether I can install Windows 8.1 from a USB stick into a Bootcamp partition. Apple's article on the topic refers to Bootcamp 5.1, but my OSX install has Bootcamp 5.0 - I am assuming 5.1 comes with the Mavericks version.  I don't want to upgrade to Mavericks because I am running out of space as it is on the OSX partition.
    Thus my question. So can I?

    Your laptop has a DVD drive, right? If so you need to burn your ISO to a disc, will not work off USB

  • 10.9.2 install Bootcamp win7 64bit iMac mid 2010 no bootable device - external superdrive, USB Stick

    Hey all,
    big problem here.
    Trying to install Bootcamp on my iMac 27" mid 2010.
    The thing is, during the installation, i get the "no bootable device" black screen, and i think i know why... but i need help.
    System, a mid 2010 imac, 2TB HD ( Original) and an SSD Samsung 1TB at the Optical Drive SATA connection.
    2TB HD is empty atm. OSX Installed on the SSD.
    Bootcamp Assistant. Problem nr. 1.
    He first did not want to let me create an USB drive. after hacking the assistat, deleting the "Pre" thing in the info.plist, that worked so far.
    https://discussions.apple.com/thread/5479879?start=105&tstart=0 and several other postings got me so far.
    Then when using the assistant, after choosing partition and so, when the iMac restarts, i get the "no bootable device" notice.
    Read a lot, and it seems, that older iMacs, that originaly came with an internal superdrive only can install win 7 from that internal superdrive.
    I have the problem, that i had it removed to put the SSD there.
    So, when doing an EFI Boot, choosing the win USB Stick or the Win in my External Superdrive, - "no bootable...."
    So i searched more. rEFIt should help. Installed, and all, doesnt work, same thing. As soon as i want to boot Win from the CD or Thumpdrive, doesnt work. :-(
    In one of the many posts, someone wrote something about starting Shell in rEFIt first, etc... didnt work as well.
    then i found this post:
    http://www.andrewsavory.com/blog/2011/2156
    sounded promissing. Somehow getting win installation files onto the Created Bootcamp partion with Virtual Mashine. But it didnt work for me.
    The VW Fusion ware is different, and non of the steps he discribes works.
    So how can i get it working.. it seems like it is somehow blocked to access something from the USB Ports.
    Logicaly i would have to get the installation files onto a Internal drive. i Tried to create a partition and copy the Win 7 USB Thump using Disk Util Progeam onto a seperate, internal partition.. but he just does not what to do that... errormessages when trying to copy it, recreate the drive, etc.
    So, i do have a 2TB internal HD, which i can use, an external superdrive, USB.Sticks. any gameplan?
    And for Error-excluding: i have an original Win 7 64 bit CD, a burnd one and controled the Hash of the loaded ISO, which i downloaded for the USB-Stick.
    Any help? pls!!!

    Hi Sam, the Mini Optical may draw too much USB power.
    Can you restore that .iso to the Flash Drive as a CD/DVD instead of an image file?

  • Cannot create your bootable usb stick

    Hi all,
    I'm new to bootcamp and I have the following problem:
    When I'm creating a Windows 7 usb drive, it gives me an error "Cannot create your bootable usb stick there was a problem copying files".
    I've tried searching google for the problem, but the only possible solutions I've got was to unmount the iso image and try again, but when I do that I still get the same error and when I check the disk utility I find the iso image is mounted again.
    Does anyone haven an idea about what to do.
    Specs:
    OS X Yosemite 10.10.2
    MacBook Pro Retina 13-inch Mid 2014
    2,6Ghz Core i%
    8 GB 1600 MHz ddr3
    Thanks in advance!

    Please see the Microsoft reference and the second link has an example.

  • Problem with T60 and USB Sticks

    All -
    I can't understand it but I have a huge problem with USB devices and my T60.
    EVERY USB device works 100% fine - despite of USB memory/HDD/other memory devices.
    Neither USB HDD or USB Sticks nor a SD drive via USB - no media is accecpted.
    I always get back: "Media not formatted".
    If I do format everthing works - but only with this notebook.
    So I am not able to share data with other computer - or not able to get my pics from my cam... 
    Please can you help?
    Thank you very much in advance,

    I hate to say it, but I agree with carbon_unit, this sounds like a Windows problem.
    As a long shot you could try uninstalling all USB hubs in Device Manager, re-install the Chipset Drivers and restart the sytem to allow the USB hubs automatically installed again. I doubt this will help, but it's all I could think of.
