Xen 2.6.25 dom0 kernel ebuild

andylyon · n00b Joined: 13 Jun 2006 Posts: 73

Hmm, I've just noticed that there is a new suse rpm kernel-source-2.6.27.5-2.1.src.rpm, when I first downloaded the suse kernel source rpm I got it from http://download.opensuse.org/factory/repo/src-oss/suse/src/ but when they updated to .4-10.2 the kernel-source-2.6.27.4-10.2.src.rpm was never available there (other kernel rpms were there, but no source), but I was able to locate it in http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/src/ instead, I assumed that the latter location was the correct place to get the latest kernel source rpm in future and I stopped checking the former, today I happened to check both folders and noticed that this time the latest version is in http://download.opensuse.org/factory/repo/src-oss/suse/src/

Anyway, I've had a quick look and as usual there are some new xen patches, and quite a lot of changes to the existing ones, including those that I had to modify to apply cleanly to vanilla 2.6.27, this release coincides nicely with gentoo-sources-2.6.27-r3.ebuild which was released yesterday, tomorrow I will update the ebuild with genpatches 5 and kernel-source-2.6.27.5-2.1.src.rpm

I will test before release and include a list of my tests.

@andylyon:

Have you tried patching vanilla 2.6.28 sources with Xen? If I wanted to do that, would you have any pointers?
I want to try current ext4 code on a domU. I know there is ext4dev support in 2.6.27, but that's not "stable" ext4 as found in 2.6.28.

Thanks for your work. :-)

Me too, since i have several issues booting the dom0 kernel on my Intel Atom system. System crashes shortly after loading 2.6.27-r2 with some xen errors which i wasnt able to copy and paste up to now.

@andylyon:

I'm having trouble booting your sources as dom0 too.
I get an error about a kernel bug, referring to hypervisor and SMP.
If I get the same error on my next try without SMP support, I'll write it down.

I am compiling 2.6.27-r4 on a 32bit (pentium4) and a 64bit (xeon 5150) machine right now.
I got two compile issues:
On 32bit: It seems like it only compiles with CONFIG_CC_OPTIMIZE_FOR_SIZE=y. Otherwise I geht this error:

Well, I ended up on a xen-sources 2.6.18-r12 for my dom0 which boots perfectly. I'm trying to create a domU now, based on vanilla-sources 2.6.28-rc7, but it will not load. I get this error when running xm create config -c:

I have been running Andy's 2.6.27-r4 Dom0 kernel for a few weeks. I can happily say no problems from the kernel, I think.

I can not seem to get usb to pass through to an XP HVm DomU. My fix for that is a pci usb card for the XP DomU, which I will hide from the DomO if necessary.
I could not get the DVD drive to be recognized until I used 'phy:/dev/sr0,hdc:cdrom,r' in the domu config file.

Another issue is that sometimes on startup there is no video or console after grub, like the machine just goes lala before X starts. I am not sure if this is the Xen kernel or the hardware support with any kernel combination. Regardless of which the problem goes away with a reboot. Also, it does not happen every time.

If anyone is experiencing similar problems please post about it.

This is my first attempt at Xen and so far it has been a challenge, but not impossible.
I am looking forward to the 2.6.28 kernel for the GEM support. This is needed for intel video on my Shuttle SG45H7 to run compiz.

Thanks to Andy for bringing us up to date!

I managed to get myself in a condition that xend will not start with 2.6.27-xen-r2.

Could not compile 2.6.27-xen-r5.

It may be that gcc-3.4.6 is too old to compile newer xen kernels.

I have successfully built these patched kernels with 4.2.4 and 4.3.2.

I have 2.6.27-r5 runnung on x86 and x86_64 machines for some time now without issues. I had to play around with the kernel config to make it compile though. I used gcc 4.1.2 for compilation since it's marked stable.
