X86 guest virtualization on XServe G5 PowerPC

All
I have a potential client where we are investigating taking their current PowerPC-based XServe G5 cluster (huge cluster) and virtualizing a bunch of x86 machines (Windows, Linux, etc) running on this cluster. If this was an Intel-based cluster it would be relatively easy I would assume, but this is PowerPC architecture.
Does Apple support bare-metal or OS-level virtualization of x86 machines on a PowerPC G5 Xserve?
If this works, what products can be used?
Anyone done this before? Tales from the field?
Thanks!

There is NO VM program that will allow you to run x86 code on PPC hardware. All code would need translation before it could even run in emulation mode. Virtual PC is the only program that did this on any kind of real scale and it was bought by Microsoft, poorly supported and eventually left for dead many OS versions ago. (I think it exists now as a way of running a different PC environment under Windows eg XP under Windows 7.) Even if you did find some way to cobble this together and get it working I doubt the performance would be even remotely acceptable - a 1 GHz PPC emulating x86 code would probably get you the equivalent of a several hundred Mhz 486 chip performance. And I have to think that the start-up time the maintenance and debugging work would be prohibitive. Many man-hours to (perhaps) get the equivalent of early-90s personal computer seems like a non-starter.
+There is Boot Camp which will let your Intel-based Mac (not sure about XServe...?)+
Last I knew the Xserve was explicitly exempted from Boot Camp support and I doubt it's changed. And, of course, Boot Camp applies only to intel chips not PPC.

  • Virtualization for XServe/OS X Server

    I currently use VMWare Fusion to virtualize Windows running on my Mac. Is there a version of Fusion that works on OS X Server that lets me run a Windows Server OS Virtualized on an XServe? I've seen Parallels Server, but after the bad experiences I've had with Parallels on the desktop, I'd rather have something from VMWare.
    Thanks!

    You can run Fusion on OS X Server. It supports headless mode (no local UI) and a VNC server for each virtual machine for remote control. Using the guest OS remote desktop is often faster/easier, but the VNC support will let you see the whole VM including booting. You can even control the VM (power, suspend, etc) through vmrun (command line) and even Automator actions.

  • Reconfigure reboot for Solaris 10 u5 x86 guest in VirtualBox

    Hello,
    I just installed the new kernal patch into a Solaris 10 u5 x86 32-bit guest OS in VirtualBox 2.0.4 on a WinXP 32-bit host. I need to do a reconfigure reboot. I can't seem to get to the ok prompt from which to use boot -r. init 0 does not work, it only offers a "push any key to reboot."
    What is the optimal way to initiate a reconfigure reboot for Solaris 10 in my setup?
    I tried the grub-based technique in which, upon reboot, I get the grub menu and push "e." That gets me to another grub screen with 3 entries. I selected the kernal entry, pushed "c" to add "-r" to the end of the line, and then "b" to reboot. Is that the best way to reconfigure reboot for Sol 10 x86.
    The above method did configure devices on reboot, but I'm not sure that is the best way to boot -r
    Thank you in advance...

    x86 machines (including virtual machines) do not have an OBP or an 'ok' prompt.
    You have to manipulate the GRUB either through interactive commands like you've shown, or by editing the menu.lst file to change boot parameters.
    Of course for reconfiguration, you also have the option of touching '/reconfigure' and doing a normal reboot.

  • Need to add additional storage to XServe G5/PowerPC G5 (3.1)

    Need additional storage for the Xserve listed below.  Any suggestions.  Need at least 1TB

    Just about any external array should work this this. Heck, if you only need 1TB then any external hard drive should work, too. Look for a FireWire-based drive since that will outperform the USB. Anything more than that will require a PCI card.

  • AIA on Oracle VM

    Hi,
    I am in the process of creating a number of VMs to implement an Applications Integration Architecture (AIA) packs. For example, I will have one Ent Linux x86 guest running say Siebel, another running Billing & Revenue Management (BRM), another EBS and a final one for SOA Suite & AIA. What's the best approach to saving these images and making them available for users to download through some menu-type application?
    The user would have a list of AIA packs to choose from and if it's AIA Pack1 that integrates Siebel-SOA-Siebel it would download those images, but if they chose AIA pack2, which integrates Siebel-SOA-BRM then it would download those images etc. Is it a matter of saving these images as templates for users to download?
    Any help would be greatly appreciated. I have seen the Oracle VM guides, but they are technically aimed at how to create templates, import/export images etc, but I was hoping to get high level information/docs that describe how best to make images available to users and how they get instantiated.
    Many thanks.
    Indy.

    I am also thinking the same lines.
    I am trying to build a lab for SOA implementation group. I would like to install EBS 11i on OEL5 and SOA suite 10.1.3.3 on another virtual server. We can add Seible, peoplesoft and JDEdwards in the future.
    I want to get your openion on the connectivity between the two virtual servers and also connectivity to these servers from individual laptops.
    Do we have templates for 11i and R12 Oracle E-Business suites?
    Thanks!

  • Can't admin XserveRAID

    I have:
    Xserve G5, PowerPC G5 (3.0), 1x2 GHz, L2 Cache (per CPU):512 KB,
    memory 2.5 GB, Bus Speed: 1 GHz, Boot ROM Version: 5.1.7f1
    And a full RAID, (sorry, I can't gather specific info on it).
    Everything is connected to both a FC switch, (QLogic 5200), and ethernet.
    For some reason I can't administrate my XserveRAID. I can see it and add it but then I get the forever spinning "Gathering info" messege. And when I try to apply settings, nothing happens. I've tried configuring the network setting both manually and using DHCP. No effect.
    Am I missing something?

    A situation can develop where the Admin looses its ability to talk to the RAID - I've had it happen to me. The first question is always about firmware version and matching RAID Admin versions.
    Assuming you have the latest of both you will need to reset the RAID in order to re-establish communications with it. At least it never came back for me over 2+ months. See the details on resetting it here. http://docs.info.apple.com/article.html?artnum=86367
    It was annoying for me but the RAID just hummed along so I waited until I could reset it without disrupting too much and since then (~5 months) everything's been fine.
    Good luck,

  • Need a good U-matic (3/4") deck

    Hey guys,
    I have about a thousand original Stella Adler U-matic tapes I need to digitize. I'm currently in the market for a few ancient U-matic deck (NTSC, preferably plays all bands). Not destroying tapes would be a definite plus as well.
    Does anyone have any suggestions? Any help would be most appreciated!
    Note: The decks will be hooked up to a Canopus ADVC300 and captured using FCP 4.5. Then backed up onto an xServe.
    PowerPC G5   Mac OS X (10.4.8)  

    Smart @#$$#SS answers aside. There's a guy here in Louisville who has every piece of gear ever made. How he keeps it all in good running condition is beyond me. Video Kitchen is the name of his business. He's pulled me out of the fire with some old equipment and tapes I need dubbed. Surely, as large as Dallas is you guys have someone like that.
    It may be more cost effective to have someone dub all of that stuff to a better format for storage etc. Just a thought if you can't find a deck you're willing to pay for.

  • NetBoot Cannot See internal Hard Drive

    I am using a Xserve G5 PowerPC G5, I use this for my netboot server. I am wanting to set this up so that I can run netboot on client machines and still see the local hard drive, however I want to be able to unmount it so that I can reimage that drive if I want or be able to run different tech tools on this. I was able to do this once or twice however I need for this to be a little bit more consistent. The image I am using runs as a diskless image, what I’m thinking is that I want to run this image diskless I just want the hard drive to be available for me to do whatever I need to do with this, any suggestions...

    afp_2U2Vgc00040A0000oM0000VU-1.2c000003 on /private/var/netboot (afpfs)
    /dev/disk0s2 on /private/var/netboot (hfs, local, nodev, nosuid)
    That's very weird. You appear to have both the afp share AND disk0 mounted at /private/var/netboot. That shouldn't be possible.
    mrenix wrote:
    Ok so then my next question is how do I correct this???
    As a workaround, you could try doing a 'mount -u /dev/disk0s2'
    How did you create this image (i.e. what was the volume sourced from)? A NetBooted volume perhaps? Though I don't think that's possible... :/

  • SBS to VM 2012 R2 migration

    Hi all
    I am after a little bit of advice and help.
    I have an existing SBS 2008 HP server and I have just received my MAPS software. As I now need to upgrade to the latest versions of the MAPS software I am looking to virtualise my servers (1 SBS and 1 2008 R2) onto a single Hyper-V server. I would like to
    keep my Exchange in house for the time being so I am looking to use the following VM's:
    1x Windows 2012 R2 as DC
    1x Windows 2012 R2 as Exchange server (with VOIP software)
    First question is should I install the full version of Windows 2012 R2 and add the Hyper-V role to it or just download and install the Hyper-V server? Is there any difference in the software?
    Second question is what is the best way to virtualise going from SBS 2008? would you suggest giving the DHCP and DNS roles to the physical server or apply them on the virtualised DC? I noticed that the Hyper-V settings ask for DHCP and DNS server details
    and this would seem to be an issue if the DHCP and DNS servers are actually VM's running on the Hyper-V server.
    Any help would be greatly appreciated as I am very new to Hyper-V
    Regards
    Gareth

    First question is should I install the full version of Windows 2012 R2 and add the Hyper-V role to it or just download and install the Hyper-V server? Is there any difference in the software?
    There is no universal consensus on which to use.
    Full Windows gets you the GUI and access to all the roles and features Windows Server has to offer. It also gives you a larger attack surface for attackers to compromise and a greater chance that you'll need to reboot for patches. Also, many of those roles
    and features lose their appeal when you find out that using most any of them in the management OS costs you one of your guest virtualization rights and when you discover that Microsoft won't support a lot of them alongside Hyper-V anyway.
    Hyper-V Server gives you a reduced attack space and less to patch at the expense of not having access to nearly as many roles and features. But, to manage it directly, you will need to be(come) fairly command-line proficient and to manage it well, you should
    be(come) PowerShell proficient. Of course, you can always manage it remotely.
    Second question is what is the best way to virtualise going from SBS 2008? would you suggest giving the DHCP and DNS roles to the physical server or apply them on the virtualised DC? I noticed that the Hyper-V settings ask for DHCP and DNS server
    details and this would seem to be an issue if the DHCP and DNS servers are actually VM's running on the Hyper-V server.
    You'll definitely want to grant your Hyper-V host a static IP address just to avoid the DHCP issue, although this is a general recommendation even when you have an external DHCP server. DNS can be a problem until the guest DNS system boots, but unless you
    have reason to believe that it won't boot, everything will be fine.

  • Oracle VM x86, enable audio to guests

    Hi, we have one x86 server Sun Fire X4170 M2 and Oracle VM Server 2.2.1 installed in it.
    We want to enable audio in a guest hosted by this server.
    We saw that the qemu command
    */usr/lib/xen/bin/qemu-dm -help*
    doesn't show the option
    soundhw
    If we are right, this is the option needed for enabling audio in guests
    (from /etc/xen/xmexample.hvm)
    # enable sound card support, [sb16|es1370|all|..,..], default none
    #soundhw='sb16'
    When we change the guest's .vm file adding the soundhw option and create the domain, we receive error messages
    *[root@ovm ~]# xm create /PATH/running_pool/11_GUEST/vm.cfg*
    Using config file "/PATH/running_pool/11_GUEST/vm.cfg".
    Error: Domain '11_GUESTS' already exists with ID '19'
    *[root@ovmserver ~]# vi /var/log/xen/qemu-dm-11_GUEST.log*
    domid: 18
    qemu: the number of cpus is 1
    /usr/lib/xen/bin/qemu-dm: invalid option -- '-soundhw'
    Additionally we tested all the possible values for soundhw (ich6, ac97, es1370, sb16, pcspk), but (as we expected) none worked.
    Has somebody enabled audio for guests in a similar scenario?
    Thanks in advance.

    Using config file "/PATH/running_pool/11_GUEST/vm.cfg".
    Error: Domain '11_GUESTS' already exists with ID '19'This means the guest is already running. You need to shut it down first.
    You may have more luck using PCI passthru to actually pass the entire sound device into the guest as a PCI device and let the guest OS handle it completely.

  • Virtualization of snow leopard server on a xserv

    Hello
    I'm looking for someone how have already use virtualization on a xserv.
    thanks

    We have an xserve + 2 Snow Leoaprd VMs + 2 Win2k3 VM's. It's mostly been used for 10-20 clients, but we're starting to move the rest of our staff on it which adds about 50 more.
    We chose vmware because of cost and stability. Parallels requires their server version which costs a lot more money than their desktop, and it didn't seem worth it if we only ran 2-3 VM's.
    Vmware also seemed more stable than Parallels5 at the time.
    It might be different now, they did not have hypervisor even announced a year ago when we last compared the two.

  • Uses for old PowerPC G4 Xserves

    I've discovered one good use for old PowerPC Xserves is to turn them into a large external FW hard drive.
    Are there any other good uses that you have discovered?  I'd like to get as much use out of them as possible.

    turn them into a large external FW hard drive
    Large, indeed. I can't think of any other FW hard drive enclosure that's anywhere close to 19" and 30" deep.
    one good use...
    I contend this isn't a particularly good use... or at least not a very efficient one.
    Your typical FW hard drive enclosure draws about 1A at 12VDC, or approximately 1/10th the power of an idle XServe G4. You're spending a lot of power spinning the fans, powering the DIMMs and driving all the other components that are irrelevant when just using it as a hard drive. You'd save space and money taking the drives out and putting them in a regular enclosure. That way you can even turn them off when not needed, without having to go through contortions when you power them back up.
    Granted, it doesn't have the 'cool' factor any more, but it depends on what's important to you.
    Are there any other good uses that you have discovered
    Given their weight I could see them having use in a personal gym. Just got to work out how to affix them to the barbell.

  • Xserve G5 second PowerPC processor, where, thanks.

    Hi there, good morning.
    I've got a MAC Xserve G5 from work, it's got a single PowerPC 2GHz processor, and now 4GB of RAM (1GB originally).
    What I'm looking to achieve here is a Dual processor machine, but I cannot seem to be able to find another processor for it anywhere, not even on eBay...
    I've seen a few PowerPC G5 2GHz on sale, but not from Xserve machines originally, so I'm not sure they'll fit on my Xserve, I know for sure the heatsink won't fit at all but not sure about the actual processor...
    I've tried every online shop I know, and nothing, maybe there is some shop somewhere else I dont know of and that I can buy another processor from?, in US maybe?
    Any info on this, greatly appreciated, thanks
    Message was edited by: JLCSan

    In the Netherlands my Apple Reseller ordered the processor, heatsink and heatsinkcover at the Apple Service Provider (CARD Services). The G5 processor in the Xserve G5 differs from the processor used in the first generation desktop G5's. If you order a replacement processor via your ASP, it's a DIY job.

  • Any known issues with a powerpc 10.5 client being supported by Lion Server running on an Xserve?

    I just got a used xServe that I am looking at installing Lion Server on rather than paying the $500 for Snow Leopard Server.  However, I have several older PowerPC based iMacs running 10.5.  The xServe will be used an a basic file server.  Any known/anticipated problems regarding compatability? 

    Thank you.  That is what I was hoping to hear.  The xServe is a late 2006 Intel with duo core with 3 GHz Xeon. 
    Your suggested migration is exectly what I had in mind.  I really was not lookging forward to the $500 hit to get Snow Leopard Server, so I was very excited about the new pricing for Lion. 
    Thank you again!

  • Xserve PowerPC G5: Configuring Lights-Out Management (LOM)

    I was wondering because the "Configure Local Machine" feature is disabled.

    Hi,
    I'm afraid the G5 Xserve doesn't have Lights Out. It's a feature only found on the Intel Xserves.
