Thread-topic: [Xen-devel] scheduling weirdness
Is it a Dual Processor system, or just a Hyperthreaded Core? I don't know if that would make much difference but it might be useful information to those in the know. Can you try it with no SMP?

Everything freshly pulled and rebuilt sunday afternoon. (no crashes 
yet; knock wood...)  Four VMs, all identical filesystems, created 
identically, running the exact same job:

# xm list
Dom  Name             Mem(MB)  CPU  State  Time(s)
0    Domain-0              54    0  r----    643.7
1    This is VM 1          63    1  -----    220.4
2    This is VM 2          63    0  -----    831.5
3    This is VM 3          63    1  -----    211.5
4    This is VM 4          63    0  -----    205.6

and VM2 is clearly running through its work much faster than the other 
three VMs.  I shut everything down, rebooted, recreated and restarted 
everything and same results.
