Hi Fabrice, Firstly, I've moved this over to the ops mailing list (dev in bcc - just so anybody following along knows where it's gone!) - I think it's more of an operational issue than a dev one.
That does seem weird - so the error is: > 2017-01-25 11:03:58.475 113231 ERROR nova.virt.libvirt.driver > [req-7bd352bf-8818-4f71-9fa0-04fabccebf9c 0329776bd1634978a7fed35a70c77479 > 7531f209e3514e3f98eb58aafa480285 - - -] [instance: > c7a5e5d1-bc22-4143-a85a-ee5c3b6777b3] Live Migration failure: Requested > operation is not valid: domain 'instance-00000187' is already active > > 2017-01-25 11:03:58.817 113231 ERROR nova.virt.libvirt.driver > [req-7bd352bf-8818-4f71-9fa0-04fabccebf9c 0329776bd1634978a7fed35a70c77479 > 7531f209e3514e3f98eb58aafa480285 - - -] [instance: > c7a5e5d1-bc22-4143-a85a-ee5c3b6777b3] Migration operation has aborted > I'm not too sure what could cause this issue, especially only one way - however here are a few things you could look into if you haven't already: You might get more info looking in the libvirt error logs, since that's a libvirt error. As a "hammer" approach grep in /var/log/libvirt on the compute hosts for "instance-00000187" - that may give a bit more insight. There should also be instance specific logs there - for example the qemu ones would be in /var/log/libvirt/qemu/instance-x.log - pretty sure kvm has similar logs. I'd say the settings from an OSA perspective are correct since it worked fine from compute2 --> 1. If you look in the conf files is anything different that stands out? Did you try migrate the same instance after it had successfully migrated? Is this consistent, so if you spun up a new instance on compute 1 and tried to migrate it to compute 2 it wouldn't work, but any that new instances that you setup on compute 2 migrate perfectly fine to compute1? That's a good start I think, hopefully we can help narrow this down! Andy
