KVM SMP Linux Guests Hang

I've the same problem, but only on amd opteron host. (opteron 6174).
No problem with intel xeon.
Host system is proxmox, basicaly, debian lenny with squeeze kernel
(2.6.32), qemu 0.12.5 or qemu 0.13.
other users reports the same problem
We have also run into the problem on our AMD Opteron KVM hosts and I'm
the author of the Proxmox post. The problem seems related to SMP.
Setting the guest to run with only one core works.
I see that there was a SMP kernel update in the 2.6.32-25 revision.
Could this have caused a regression?
Here's a link to the Proxmox sources for their deb packages.

Title:
Update to 10.04
I've tried it on an Ubuntu 10.04 64bit host, with qemu-kvm 0.12.3
+noroms-0ubuntu9.2 , and a Lucid 64bit guest with kernel 2.6.32-26. Host
is an AMD Phenom II X3 720, not exactly an Opteron but it's AMD.
What I observed is when starting the guest from a powered off position it boots
much faster
It seems to me the boot time after the reboot is related to the uptime
somehow... I'm up to 60second freeze now on one VM running a 10.04 64bit
guest with 3 CPUs. The kernel loads, then there's 60 seconds silence, when
nothing happens, and then it continues to boot.
If I stop the vm and restart
Its with a 10.04 server 64 bit Guest on 3 cores (dont know with one)
host is debian 5 latest updates
And it defently freezes not for 60 sek, not for 60 min. forever (or
better as long the system get electric power lol)
Btw i turned off splash etc as described bevore it freezes at freeing
both host and guest are 64 bit.
i said it have to be moved maybe but wasnt shure where to fill it exactly.
anyway
it seems to happen when you run quemu/kvm on the host (at least 64 bit debian)
and guest 10.04lts 64 bit guest and make latest kernel update.
its everytime reproduceable
its happen
i said it have to be moved maybe but wasnt shure where to fill it
exactly.
Thanks, I didn't know what you'd meant by that. I've marked this as
affecting the kernel. Leann, I'm afraid I'm not sure how to mark it as
affecting precisely the Lucid kernel.
but still if the host (different distri
Thank you for taking the time to report this bug and helping to make

What is the software version running on the host?

Update to 10.04
Host is Debian 5.0 with all latest Updates.
BTW Status should be critical. I See a lot of People running into same
issue.
BTW2, if the host makes a difference then its even more concerning since
kvm should be full virtualisation the combination host version and guest
kernel shouldnt make a
I can't reproduce this on a maverick host. Are you using a 32- or 64-bit
guest? What about the host?
You filed this against Ubuntu's qemu package, but you said you are using
Debian 5.0 host. So isn't this bug actually against both the Debian qemu
package and the Ubuntu lucid kernel?
