Re: [OpenStack][Nova] Live Migration Error

 

Ok, so i've updated to the test packages from

The migration still fails, but i see no errors in the logs. I'm trying to
migrate a VM with the m1.tiny flavor from one machine to another. Their
hardware are identical and they have more than enough resources to support
the m1.tiny flavor:

cloud35         (total)                         4    3867     186
> cloud35         (used_now)                      0     312       5
> cloud35         (used_max)                      0       0       0


These are the logs from the origin compute node:
http://paste.openstack.org/show/19319/  and  the destination compute node:
http://paste.openstack.org/show/19318/ . The scheduler's log has no visible
errors or stack traces.

I'm still using nfsv4.

Any ideas?
