Hi !
After recent update, I've noticed that some VM's not running.
There is error message:
Code: 
TASK ERROR: host NUMA node1 doesn't exist
The virtual machine has 2 sockets with 2 cores, numa=1
The hypervisor has single Xeon E3-1270 processor

So, when I disable numa, or reduce sockets to 1 - virtual machine starts. When I run kvm process from command line with enabled numa and 2 cores - virtual machine starts. Earlier, here was no problem to start 2 core VM on single core hypervisor with enabled numa. So please, tell me - is it's a bug, or new "feature" ?

Thank you for answer.
Yes, of course - on single socket system I don't need NUMA, but I have mixed setup with single and two socket hosts, and want to be able live-migrate VM from one to another, especially for HA.
 
In recent update the problem is solved.
