Xen anyone?

Has anyone gotten Xen 3.X to work on Arch?
I have tried two packages from the AUR and neither have worked as is. (Xen (3.2) and Xen-Bin (3.1) ).
If anyone has, I would appreciate any pointers that could be provided. The quick results from the above two packages are:
xen 3.2 - actually, couldn't build since it is missing a file. I tried to download the file from the xen.org site. I could not get the makepkg to run (compile keep error out on the same error)
xen-bin 3.1 - I have gotten a couple of different errors here.
First, the install (makepkg worked great) did not build the kernel26xen.img correctly. So I tried a bunch of things; but never could get mkinitcpio to create an image that would boot. I keep getting an error about the /dev/sda3 root partition not found/valid.
Second, I tried to create the kernel image with mkinitrd. I final got this to work (needed to run depmod -a 2.6.18-xen first and modify the mkinitrd.conf file). However, with this I am now stuck at loading the kernel image and am getting the following error:
mdadm: No arrays found in config file
mount: Mounting /dev/root on /new_root failed: No such device or address
pivot_root: pivot_root: No such file or directory
mount: /initrd: No such file or directory
mount: /initrd: No such file or directory

Enter 'help' for a list of built-in commands.
/bin/sh: can't access tty; job control turned off
If anyone has experience (or thoughts) on how to get xen working on Archlinux, I would appreciate any help. I still want to try to get it to work on Arch but recognize I might need to change underlying OSes.
Chris....

Can you try these packages?

Keep in mind that the kernel Xen uses (2.6.18) may not have support for your disk controller.

Recent kernel problem with VT? (system freezes) (KVM, VirtualBox)

My system freezes when I try to use KVM (or VirtualBox with Intel VT enabled)
It also crashes on with Fedora 11 beta, so maybe this is 2.6.29-related.
(I can use full virtualization with OpenSUSE 11.1, Xen)
Anyone an idea? Which bugtracker should I use for something like this....
Some specs:
/ uses ext4
Core 2 Duo 8500
Intel VT is enabled in BIOS

Vmware runs fine.
I havent tested anything else..
and yeah the recent kernel started the issue.

How to setup grub2 with arch linux and xen, lvm on luks

OK, so I tried downloading this package from AUR: https://aur.archlinux.org/packages/xen-git/ , but that has patching problems as noted in the comments. It looks like the packagebuild sets up all the xen stuff for you, but I can't seem to get the package to install because of the error's while patching. If anyone can point me in the right direction on what all the extra files in the PKGBUILD are for or how to debug problems with PKGBUILDs not working because of patches.
So next I just tried to compile the latest xen from git://xenbits.xen.org/xen.git (with ./configure, make, make install) and that seemed to go fine, but I'm a bit confused:
1. Do I have to do any additional configuration for xen when working with arch linux? On ubuntu I could just compile the source, update grub, and make sure to start the x services at runtime.
2. How do I set up grub to load xen with this setup? Right now this is my /boot/grub/grub.cfg:
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"

I've tried throwing in a line like: XEN_HYPERVISOR_CMDLINE="cryptdevice=/dev/sda3:vgStorage", but nothing new shows up on the grub boot menu.
First time trying to set up a non-ubuntu system, please help!

As for XEN.... well you could always try QEMU/KVM or LXC.
As for the LVM2-on-LUKS/dm-crypt

Alphabetical UUIS is the BOOT partition
hd1,msdos2 AND ahci1,msdos2 are how the Grub Bootloader numbers the drives not Linux.
I have my BOOT partition on a USB stick, and it is the Second partition.
So, that would make it, Device 2 and Partition 2
Device numbering starts at 0
Partition numbering starts at 1
Oh, and note that you don't need ":allow-discards" ... at all but certainly if you don't have an SSD. Also note that I included the line numbers so it is very clear that I didn't post the whole thing, but instead what I thought was relevant. Finally, I am loading modules that I don't even need, but what the hell... if it ain't broke, don't fix it

Requesting some changes for xen PKGBUILD to work with --enable-ovmf

For background about this issue, you may want to read these two E-Mails to edk2 Mailing List:
http://sourceforge.net/p/edk2/mailman/e … sg32776907
http://sourceforge.net/p/edk2/mailman/e … sg32793684
Basically, it goes like this:
- Xen can be compiled with the optional --enable-ovmf option, so it can make DomU VMs using UEFI Firmware. Instructions here:
http://wiki.xen.org/wiki/OVMF
This can be done in Arch Linux by adding in the ./configure line of PKGBUILD --enable-ovmf, adding an additional step where makepkg downloads Source Code from edk2 repository.
- Currently, it fails to build that way with this error:
http://lists.xen.org/archives/html/xen- … 02855.html
This error is caused because the edk2 Source Code that xen pulls during build is fresh and doesn't include any patch to make it aware that Arch Linux has both Python 3 (python) and Python 2 (python2). By default, it tries to compile with Python 3, so it fails.
- Assuming than the Python version issue was fixed (I did it in a non-elegant way, replacing /usr/bin/python with /usr/bin/python2), it will still fail with this error:
https://bugs.archlinux.org/task/40277
https://aur.archlinux.org/packages/ovmf-svn/ (Some of the latest comments)
This error is caused by building with GCC 4.9, earlier versions seems unaffected.
The AUR has also a very similar package (If not identical) that is based on edk2 Source Code, the same which xen downloads while building, ovmf-svn:
https://aur.archlinux.org/packages/ovmf-svn/
This one has a PKGBUILD which includes some lines that seem to point that it is aware of both the python version issue, and the GCC 4.9 build issue, by providing a patch:
https://aur.archlinux.org/packages/ov/ovmf-svn/PKGBUILD
Reelevant lines seems to be these ones:
msg "Fix GenFw: ERROR 3000: Invalid, Unsupported section alignment"
patch -Np1 -i "${srcdir}/edk2-basetools-add-gcc4.9-support.patch" || true
patch -Np1 -i "${srcdir}/edk2-ovmfpkg-add-gcc4.9-support.patch" || true
msg "Use python2 for UDK BaseTools"
sed 's|python |python2 |g' -i "${EDK_TOOLS_PATH}/BinWrappers/PosixLike"/* || true
sed 's|python |python2 |g' -i "${EDK_TOOLS_PATH}/Tests/GNUmakefile"
I didn't found any info regarding if Xen can work with OVMF ready-to-use binaries, or either building ovmf-svn, which I didn't tested but I suppose should build properly. All instructions regarding using Xen with OVMF request that it is added as option during build time. This forces me to have to modify the edk2 Source Code that xen downloads.
Basically, what I want to request is if xen PKGBUILD can be modified to include a statement that checks if --enable-ovmf is being used, then make the appropriate changes to the edk2 Source Code that gets downloaded while building Xen so it successfully builds. This could *POSSIBILY* be based on existing ovmf-svn PKGBUILD code.
This change could also be applied to other xen-based packages that can also be builded with --enable-ovmf and presents the same issues.

FINALLY managed to get this thing working:
http://i.imgur.com/ZWTRcn0.png
I tried to build xen with --with-system-ovmf= as suggested like ten times or so, with no success. While xen seemed to build fine, when I tried to create a UEFI DomU, it simply opens and inmediately closes, through if using SeaBIOS worked fine. On xen IRC there was another Arch Linux user claiming that he recently got Xen with OVMF working using that parameter and the bios.bin binary from the ovmf-bin package from AUR. Installing ovmf-bin then providing xen the full path (--with-system-ovmf=/usr/share/ovmf/bios.bin) didn't worked, neither building ovmf-svn myself then using ovmf_x64.bin (Or renaming it to OVMF.fd, ovmf.bin, etc). It always builded perfectly, yet it failed to make a UEFI DomU. Still, both Firmwares worked when using qemu from the official Arch Linux repository (Note that ovmf-bin bios.bin is 1 MiB in size while ovmf-svn ovmf_x64.bin is 2 MiB, not sure what accounts for the difference).
So how I got it working? A bit complex:
- While in my first post I mention that ovmf-svn had a patch for GCC 4.9, it seems than the patch was removed in the last two days. Without the patch, ovmf-svn still builded properly, so I expected than the GCC 4.9 fix got included in edk2 Source Repository. This was blocking me earlier, so decided to give --enable-ovmf another go.
- Renamed python2 to python as a workaround to not have to touch the edk2 tree that xen downloads, which worked the last time.
- Used makepkg with --enable-ovmf in the PKGBUILD ./configure line. I expected it to work due what I mentioned earlier, but it still fails with the GCC 4.9's GenFw: ERROR 3000.
- As a last resort measure, I decided to try to merge into xen the source that ovmf-svn PKGBUILD modifies, as that one builds properly.
- I replaced all the directories inside xen/src/xen-4.4.1/tools/firmware/ovmf-dir-remote/ with the ones from ovmf-svn/src/tianocore-edk2-svn_build/. Not all directories were replaced, seems than ovmf-svn just downloads the parts of the tree required for building the OVMF Firmware, not everything, which xen does.
- Used makepkg again, which used the existing source to try to build again.
- It builded, no python or GenFw error. Installed the new package, rebooted, tried to make the UEFI DomU and BAM! There it is, as you can see in the Screenshot.
Why can some users get this running with just providing bios.bin from ovmf-bin while I have to do a walk around the globe is anyone guess...
To not derail this request further, I can say the following:
- Assuming than --with-system-ovmf= works consistently, which for me didn't, is currently possible to build Xen with OVMF, so making a more complex PKGBUILD to be able to use --enable-ovmf may not be needed.
- --enable-ovmf is still useful because it may reduce a two-step process (Installing ovmf-bin or building ovmf-svn) into one, through I'm not sure if there are pros/cons for each approach besides than you will have latest OVMF version compared to the ready-to-use binary. It also makes xen package more compatible with the mainstream Xen instructions, as --with-system-ovmf= is quite unknow.
These decisions are for kantras to make.

AJA Xena LS and Premiere CS4 color correction

Is anyone using the AJA Xena LS with Premiere Pro CS4?
I have a problem with color correction and it appears that the Xena card could be the reason for it.
When I apply a color correction to a clip, the color correction takes effect only as long as the left mouse button is pressed but doesn't retain the correction once the LMB is released (see my previous post "CS4 video effects" for more details).
Any input (other than the help already provided in the "CS4 video effects" post) will be appreciated.
Thanks!

This problem was solved with the new Xena drivers released 09-04-09.
New problems occurred, but they are specifically AJA related.

Xen DomU Primary server - Upgrade from 10.3.4 to ZCM 11.2.x

I have a ZCM 10.3.4 service running on a XEN SLES11-sp1 paravrtualised DomU.
The ZCM upgrade to 11.2 instructions warn against extracting the ZCM 11.2 iso file and using that as the upgrade source, instead recommending creating a physical DVD and using that as the source.
As I have a vitualised server I assumed it would be easy to mount the iso as a virtual CD for the guest to use and crack on with the install... but after finding the virt-manager 'add a CD/DVD' option didn't
give me the results I was hoping for (a nice shiny CD icon on the desktop of the virtual server and a 'there it is!' moment after opening nautilus...) I attempted to follow the SuSE instructions for attaching
a CD reader Block device. This asks you to attach a device tap:cdrom:/dev/sr0 or file:/path to iso/ zcm112.iso to an unused block device (say xvdb) and then mount the block device to the DomU guest's
file system (/mnt/xvdb... for example).
This is great for accessing the data, but to my eyes accessing the DVD's installation files from a mounted directory on the guest server isn't any different to extracting the CD/DVD and trying to run the
install from the extracted files on a standard physical box.
Does anyone know why extracting the install iso isn't recommended and more importantly how to upgrade ZCM 10.3 running on a XEN virtual server to 11.2?
cheers

Kona 3 [and XENA] for FCP Questions

Is the XENA 2Ke compatible with the Macintosh platform and FCP, and if so which is the recommended version of OSX and FCP?
I have previously read someone stating that you can use this card on both platforms therefor negating the need to purchase a Mac only Kona 3.
I am doubtful of this however your immediate response / confirmation / denial of this is greatly appreciated.
ALSO
Is anyone aware of news relating to an upgrade of the Kona 3 card [ie Kona 4 or a Mac and PC compatible XENA card]?
I am looking at assembling a new HD online capable suite in the next few weeks and am hoping to avoid purchasing ie a Kona 3 card just before the release of [theoretically] a Kona 4 card [possibly at NAB 08]. Being that 4K / Red post are and should be at a premium in the coming months I would like to assemble a post solution that can handle for example a short form 4K online [if possible].
I know I am dealing with a lot of what-ifs but for the investment I need to make I will be asking similar questions to these everywhere I can including the forums such as this.

Anyone / everyone please feel free to comment
Hi Jerry
First and foremost, thank you very much for your detailed reply.
1. Hmmmm. "AJA, is there something in the air too?" [lol].
I just love the thought of new gear and technology... and AJA furthering its hardware support of RED in FCP, looking forward to any NAB developments.
*2. Regarding the Xena-2Ke for Mac.* Just received a reply from AJA Tech Support stating the following:
+"Hi Mitch,+
+The Xena-2Ke is compatible with Mac OSX 10.3.x, 10.4.x and 10.5.x running+

+On the other hand A Kona 3 is not compatible with Windows.+

*3. Monitoring 2K?* What are you using to monitor 2K, HD Jerry?
Many guys in similar situations to myself over here in Australia are using Apple Cinema Displays with a Decklink HD-Link Pro box for monitoring. Obviously the 30" Cinema Display has the resolution to handle 2K monitoring but is it suitable in your view?
Realistically I am looking at offering an immediate service based mainly on a HD offline / online workflow. I would however like to future proof myself as best I can by assembling hardware that can handle 2K with reliability, stability and to reasonable levels of accuracy and complexity.
*Up until now [NAB] I've been looking at something in the order of the following setup:*
*Online Machine*
Two 3.2GHz Quad-Core Intel Xeon (8-core)
8gb RAM
1TB 7200-rpm Serial ATA 3GB/s
NVIDIA Quadro FX 5600 1.5GB (Stereo 3D, two dual-link DVI)
One 16x SuperDrive
AirPort Extreme card (Wi-Fi)
Apple wireless Mighty Mouse
Apple Wireless Keyboard
*Third Party Card / Hardware IO:*
Kona 3 with K-Box
*Offline Machine:*
Two 3.2GHz Quad-Core Intel Xeon (8-core)
4GB (2 x 1GB)
1TB 7200-rpm Serial ATA 3GB/s
NVIDIA GeForce 8800 GT 512MB (Two dual-link DVI)
One 16x SuperDrive
AirPort Extreme card (Wi-Fi)
Apple wireless Mighty Mouse
Apple Wireless Keyboard
Monitoring:
JVC DT-V24L1DGE 1920x1080 Pro HD LCD with 1:1 pixel monitoring / no scaling and all the regular / required inputs and features
*BUP / Archival Purposes / Proofs:*
Lacie D2 Ext Blu Ray Burner
Storage:
Caldigit's HD Pro OR G Technology's G Speed OR G Speed es [though not sold on G Speed es - great price point but really doesn't have the sustained drive speeds. Great for online SD, Pro Res and possibly basic DVCPro HD / HD Sequences etc. [www.g-technology.com states "Two G-SPEED eS units and the G-Tech PCIe RAID controller support all of the above plus 10-bit, 1080i/60 HD playback in RAID 0 or RAID 5 mode."]. Will be looking into the new Apple owned Promise RAIDs too; your thoughts on these? Unfortunately I don't really have the budget for SANman, X-Serve, Fibrejet etc solutions at present but for the right job, that would obviously change.
I really appreciate the idea of how you are working with 2K, though your description was not really that detailed it definitely sounds smooth. Do you think that I am heading in the right direction in your opinion with the gear I have in mind, and is the minimum 2K future proofing concept I have a valid one?
Thanks for taking the time to read this post, and hopefully reply to some or all.

Packet Loss on Xen and Coherence

We are currently experiencing packet loss issues with Coherence 3.4.2 during the datagram test.
Packet loss statistics are as follows:
Rx from publisher: /10.96.67.169:9999
elapsed: 149384ms
packet size: 1468
throughput: 66 MB/sec
46889 packets/sec
received: 7004519 of 8252377

out of order: 0
avg offset: 0
gaps: 535018
avg gap size: 2
avg gap time: 0ms
avg ack time: -1.0E-6ms; acks 0
The Coherence implementation is running on a Xen VM.
We see this happen for both Fully Virtual and Paravirtualized Guests.
This problem does not happen on physical hardware.
Here is the general sequence that we tried:
1. After finding the problem on coherence, we tried to simulate similar results on 2 HVM xen systems and we did not find the problem there.
        a. These boxes were HVM guests.
        b. Were running kernel 2.6.18-164 and redhat 5.4
        c. These guests were running on Dom-0 kernel of 2.6.18-164.2.1el5xen
2. We had 2 para virt machines on the same Dom-0 as above but they were redhat 5.2 so we ran the same test there and still we were running into problem.
3. We upgraded the para virt machines to redhat 5.4 with latest patch rev and still problem was present.
4. after this research found out that we need to disabled module ipv6 and that seems to fix the problem. After disabling IPv6 module ran some more tests between pl1rap704-beta and pl1rap706-beta. Results were performance improved but still packet loss.
5. We converted 2 para virt guests to HVM guests (pl1rap704-beta and pl1rap705-beta) and ran the tests it was still having problem.
6. Upgrade pl1rap704-beta and pl1rap705-beta to redhat release 5.4 and latest kernel rev and see if the problem is still there
We haven't tried this on Oracle VM, but think that would be the next step to see if the problem persists there, although Oracle support indicates that Coherence is not officially supported on Oracle VM.
We still see the packet loss issues and wonder if anyone has encountered this issue before and has a solution to it?

Just saw your post.
If still a problem.....send a PM to   Heather_VZ she has been very helpful to many people on many subjects

DOM for thinkserver models to load xen or vmware?

I just go tmy first Lenovo TD230 in. Looking at replacing a lot of Dell servers with these and the RD240 as well.
With Dell we would order a USB/Flash model to install internally that had Xen Server or VMWare preinstalled. Is there something similar with VMWare or do I need to just install drives and create a small partition (or separate RAID array) for the vmware OS.
From what I read XenServer is not supported on the TD230 because of RAID driver issue. Just wanted to see if anyone had any advise to offer.
Thanks!

FMS 3 and Xen Virtualization

Has anyone tried using FMS 3 and Xen in a medium to large
production environment ?
I know that FMS and virtualization is not officially
supported, and that using VMware provides several performance
decreases. But is that also relevant to Xen ?
Xen support an option to activate an independant wallclock,
to remove all clock drifts / jitter.
Since this was one of the major problems with VMware, I would
like to know if there could be additional problems in a virtualized
environment.
Versions,
Linux: 2.6.18 (Debian Xen kernel)
Xen 3.2.0
FMS 3.0.2-r217

DVR is supported from FMS 3.5 and not from FMS 3.
Now coming to the question, yes DVR is done via server-side code (though you can do direct client-side record - but its not preferred way of doing it)
There is no built-in player as such but Adobe does provide ready-to-use solution for DVR which is called dvrcast. You can find dvrcast application on FMS tools page - http://www.adobe.com/products/flashmediaserver/tool_downloads/ . The solution comes with two server-side applications + FLVPlayback component which can be used on client side.

Oracle on Xen: Ambigous information - Metalink vs. SAP notes

Note 1173954 - Support of Oracle for VMWare and XEN states:
<...>
Oracle is not certifying any of its products on XEN and VMWare virtualized environments.
<...>
but Metalink 563608.1 states
<...>
As the Xen kernel is shipped by the Operating System Vendor, and it is not tainted, it is fine for Oracle, and it is certified to be used.
<...>
Can anyone please elaborate what is correct?
Markus

Hi Markus,
the SAP note has been written by the Oracle development support at SAP. These are Oracle guys.
So for SAP customers this is the current state of affairs.
Anyhow, Metalink 563608.1 is about Oracle 11g which is not even released for SAP yet. Also it has not been reviewed yet - so it may be subject to change.
More information are also available in Metalink 249212.1 (VMWare usage).
Anyhow, since SAP is moving strongly towards supporting virtual environments now for quite some time, I would assume, that XEN Support will be given also for Oracle platforms sooner or later.
But for now: better don't use it for production systems.
Best regards,
Lars

CS4 support for AJA Xena...PLEASE!!!!!

Howdy everyone. Is there anyone who might know if Adobe or AJA Xena will ever be supported with CS4 (especially in 64bit Windows) I would think Adobe would be interested in helping AJA resolve its problems with releasing a CS4 operable driver. It's a great capture card and CS4 promises to be a great package. But alas both are losing the game by not providing support between the two great products. I don't know what the hang up is, but CS4 would sell more copies to AJA users if this highly desirable driver existed. Anyone. Anyone.

Talk to the AJA folks.

[solved] stock kernel boot on xen fail

Hi all,
I install the archlinux on xen (http://prgmr.com/xen/) with the formal kernel
when boot the system, I get this error
xc_dom_probe_bzimage_kernel: unknown compression format
Anyone know how to solve it?

Thanks for your reply. I have changed to use kernel26-xen from aur and it works.
It seems that the stock kernel uses xz to compress bzImage. And pygrub should only support gzip bzImage (https://bugzilla.redhat.com/show_bug.cgi?id=515831) for xen3.x. For xen4.0, lzma and bzip2 are supported
(http://wiki.xensource.com/xenwiki/Xen4.0)
[hongy19@Archlinux linux-2.6.38-ARCH]$ cat .config |grep -i config_kernel
# CONFIG_KERNEL_GZIP is not set
# CONFIG_KERNEL_BZIP2 is not set
# CONFIG_KERNEL_LZMA is not set
CONFIG_KERNEL_XZ=y
# CONFIG_KERNEL_LZO is not set
So I guess the stock kernel could not used with xen right now.

Any XEN host + OSX / XP guest's yet ???

Would have done it myself but waiting for Apple + Mac Pro + 2x quad core + dual SLI nvidia 8800gtx or Mac book pro qaud core + 8800gtx min before buying and maybe the next cat OSX tiger / leopard / cheetah / bob cat ???? whatever they are calling it now.
Is there anyone that tried to install XEN host with OSX and XP guest's for gaming.
Obviously it will fry a mac min / mac book pro so likely only Mac Pro usage and 7800+ or 8800 nvidia ??
Might be a solution to lack of games for OSX
Link's might be of help / similar action for OSX guest install
http://www.gentoo-wiki.com/Xen
http://wiki.xensource.com/xenwiki/ "pdf" for info on Xp install as guest.

Anyone have any thoughts on this? I still haven't been able to solve it. Here's the Vbox.log
Thanks!
Scott
