In a way. Binaries no, but you can get the kernel sources at
git://git.gitorious.org/opensuse . Just rewind HEAD to a tree that contains
the 2.6.32 version patches.

I've not yet had luck compiling a Xen kernel and having it boot. I'll see how
far I get this time ...

Is this a problem only with the 32-bit kernel?

I don't know. 32-bit's the only installed scenario I have to test

Is this only visible when using pv-grub?

As per OP, yes.

Also, please attach logs rather than posting them inline, to keep the
bug manageable.

noted.

Finally, to keep a clean picture, please make sure you use hypervisor and
tools packages from 11.3 when reporting bugs against this product.

i don't own the Dom0; it's not opensuse.

as for the DomU,

xen-libs-4.0.0_21091_05-6.6.i586
xen-tools-domU-4.0.0_21091_05-6.6.i586

are from


http://download.opensuse.org/distribution/11.3/repo/oss/suse/i586/xen-libs-4.0.0_21091_05-6.6.i586.rpm

Also, we'll need "xm dmesg" output associated with this (perhaps after adding
"loglvl=all guest_loglvl=all" to the Xen command line).

I don't have access to the Dom0 host boot config. Only to out-of-band console
'logview' log access, which I've presented.

Seems like the code is being mis-compiled (see bug 639756), but the
mis-compilation (due to other code changes) doesn't happen anymore with
kernels 2.6.34.6 or newer. You may want to try the one at
http://download.opensuse.org/update/11.3-test/rpm/i586/.

installing just the kernel,

rpm -qa | egrep "^kernel|xen-"
kernel-xen-2.6.34.7-0.2.2.i586
xen-libs-4.0.0_21091_05-6.6.i586
xen-tools-domU-4.0.0_21091_05-6.6.i586

boot from pv-grub, 32-bit, is apparently now successful (apart from the kernel
module version mismatches caused),

uname -a
Linux edge 2.6.34.7-0.2-xen #1 SMP 2010-09-14 14:21:06 +0200 i686 i686 i386
GNU/Linux

when are this kernel, and associated deps, planned to be promoted to
release/update distro?

thanks.
