Hi all,
I have 2 question:

1.In /etc/nova/nova.conf, I find two variable 
allow_resize_to_same_host
allow_migrate_to_same_host
when set to true, can do migrate on single node.
Is it possible to do live migration on single node?

2.I encouter:
ERROR nova.virt.libvirt.driver 
CPU doesn't have compatibility.
internal error: Unknown CPU feature invtsc
so I want to debug nova-compute to find out the reason.
Can someone give some hint for debug nova-compute?

Thanks in advance.
