Hi all, I¹m having trouble migrating a virtual instance to another host. I¹m setting up a small private openstack environment. Currently I only have two hosts; call them os1 and os2. Os1 is the controller and also a compute node, and os2 is a compute node. There is one vm running on os2, and I'd like to move it to os1 for reasons that are immaterial.
Currently I can¹t use nova¹s Œlive-migration¹ command, because the cpus differ. Os1 has as an Intel Xeon E7-4807, and os2 has an Intel Xeon E5-2620. I¹ve tried to use the `nova migrate` and the `host-servers-migrate` commands which should, if my understanding is correct, bring down the instance and then migrate it, but the instance stays on os2. I should also mention that there is no shared storage for the two hosts, that the instance was booted from qcow without any volumes, and that the disk for this instance resides on os2:/var/lib/nova/instances/<instance>/disk I can think of a couple possible solutions: 1. Bring the instance down, change the libvirt.xml cpu model, bring the instance up, and live-migrate - How do I find a lowest-common-denominator cpu? - Does openstack observe the Œmodel¹ parameter in the libvirt.xml? I read that it didn¹t in the past. 2. Create a snapshot of the instance and boot it using the ‹availability-zone <zone>:<host> parameter Is there any other way to do this? I read a blueprint from Juno about adding a destination host parameter to the Œmigrate¹ command, but it seems it was put on indefinite hold, and it isn¹t in Kilo. Is this something that will be added? Thanks!
