If not a duplicate of bug 820112, maybe it's of bug 844376.

Please try what's reported in https://bugzilla.redhat.com/show_bug.cgi?id=820112#c58 and see if it makes sense in this bug as well.

I tried what's reported in https://bugzilla.redhat.com/show_bug.cgi?id=820112#c58

Host sometimes crash no matter vnc or qxl. the difference is that, for vnc, the guest always got BSOD while qxl not

Summary:

   1. with vnc 
     result:BSOD + sometimes host crash

   2. with vnc and numa
     result:guest work well(and cpu usage is normal) + sometimes host crash(as Description os this bug)
   
   3. with spice qxl
     result:guest don't show BSOD but cpu usage is 100%(guest response is very slow) + sometimes host crash

I do not think it's duplicate to bug 844376, as no host crash is mentioned in bug 844376.

Probably DUP of bug 827031. Retset with the fix (kernel-2.6.32-288.el6 or later)

Hello, Gleb Natapov and Karen Noel,
I am in the waiting list for the 48 core AMD machine. It will need around 6 days later.
I will test this with kernel-2.6.32-288.el6 or later as soon as I got the machine.
I will let you know the result at first time.

This problem could not be reproduced by using the kernel-2.6.32-288.el6. Starting a KVM guest with 48 core and 256G memory successfully on the AMD machine.

Testing with spice qxl, there is no crash found on host side.
