Subject Re: Timeout with live migration
Date Tue, 13 Oct 2015 00:17:44 GMT
The slow transfer is related to the storage we are trying to migrate off of.  We are capable
of getting about 350mbps off the disks but when we are moving volumes that are greater than
about 500GB we end up racing the clock and hoping that the migration finishes before the job
times out.   It would be awesome to be able to manage that timeout and I know there are a
ton of settings I just don't know about and am hoping someone might be able to point me in
the right direction.

I would first check your NICs' speed and load, the amount of RAM allocated
for the migrating VM and than check the hypervisor log files.
