Comment 1 Markus Armbruster 2006-12-08 04:36:26 EST
Update to backport of latest upstream version (bz#218050) will resolve this.

Comment 3 Jarod Wilson 2006-12-21 09:34:49 EST
Latest upstream backport required a bit more patching to run on ia64 (posted to
rhkernel-list and virtualist), but works now, at least as far as firing up
graphics is concerned. Still looking into a hang on shutdown that appears to
only trigger when graphics are turned on.

Crash running against vmcore from hanging xen guest

Unfortunately, because ia64 xen guest crash dump process doen't lay down a
"switch_stack" register dump on the kernel stack of the panicking process, we
don't get a completely useful dump. Without that info, its impossible to get a
backtrace of the crashing process (Dave Anderson can explain in further
detail). Not seeing much of anything useful in the log output either....
Comment 6 Jarod Wilson 2007-01-05 13:19:42 EST
The guest shutdown hang is now being tracked in bug 221626.

Comment 8 Jarod Wilson 2007-01-31 14:50:55 EST
Note that the shutdown hang mentioned in comment #3 only manifests itself if a
'poweroff' command is issued from a shell within the guest itself -- the
Shutdown button in virt-manager and xm shutdown both work.
Comment 9 RHEL Product and Program Management 2007-03-29 14:45:22 EDT

Hat Enterprise Linux maintenance release.  Product Management has requested

products.  This request is not yet committed for inclusion in an Update
Comment 14 Markus Armbruster 2007-06-07 09:28:37 EDT
We're considering updates to hypervisor and libxc, which should remove the need
for the attached patch.  Jarod, please confirm using the latest kernel-xen and
xen from the appropriate branches.
Comment 15 Jarod Wilson 2007-06-19 17:44:04 EDT
For the moment, the latest kernel and xen combo does indeed provide a working
paravirt framebuffer on ia64 without need for any additional patching. However,
with the current x86_64 breakage and it being up in the air which ia64 patch is
at fault, I'd like to retest this once that is all sorted out.
Comment 16 Jarod Wilson 2007-06-21 16:34:48 EDT
So it turned out not to be one of the ia64 patches, and with the latest kernel,
things are still working just fine. I'm going to say we're good to go on this one.
