To manage
@Tomokazu:
To recap, the oneiric version of kvm on an oneiric host fails to reboot,
and the upstream qemu on a *precise* host reboots fine? You have not
tried the precise qemu on a precise host, right? Looking at qemu
changes, I suspect that this should be fixed in precise.
At first I thought
@Serge:
Yes, I have not tried the precise qemu on a precise host.
I will push a natty and oneiric package with those fixes to ppa:serge-hallyn/

I rebooted test VM with your qemu-kvm (1.0+noroms-20120220-0ubuntu1).

This VM booted without any problem.
So is problem fixed with daily build ? Can you find the patch with Natty
based qemu-kvm .deb ?
Thank you for helping us. :D

I assume you mean you must use natty in production, and you are asking
whether the fix in upstream will be back-portable?
At this point I don't even know whether upstream will fix it. If it
does, then I'll try to find the patch which fixed it. If not, then we
can report the bug

Thanks very much for testing again.

To manage notifications about this bug go to:
@Tomokazu - the patch was only to make upstream qemu compile. It
doesn't change its behavior.
If libvirt must be used then perhaps we need to more closely reproduce
the configure options used in the package. In which case it might be
easier to create a daily build.

@tomokazu: I've queued up a qemu package based on the latest qemu-kvm

@serge:
Now, I started to debug with your qemu-kvm (1.0+noroms-20120220-0ubuntu1).
3 days later, I will reboot VM on this host.
I built this environment this way.
* clean install 12.04 precise from alpha iso
* add your repository (ppa:serge-hallyn/virt)
* install qemu-kvm libvirt-bin
I tried to reboot VM with this patched qemu.
uptime : 3days
reboot : 2012/02/20 09:42:50 - can not boot
stop at : ACPI: core revision 20060707
3 days before, I did this operation :
% virsh destroy ${VM}
% git clone git://git.qemu.org/gemu.git
% apt-get build-dep qemu-kvm
% cd qemu

If you have a chance to try to reproduce this with upstream qemu, we
could get them involved in debugging this.
(Upstream qemu means:
git clone git://git.qemu.org/qemu.git
apt-get build-dep qemu-kvm

My guest shows this problem only after a couple of time. 4-7days uptime!
When I boot my guest and reboot it afterwords it's not showing the problem. It
