Hi, Just to add that this bug was recently brought up in openstack-dev [1] it sounds that you are waiting for fix via [2] or, probably more likely [3] Disabling DiskFilter sounds like OK workaround in case your VMs are never booted from image in your OpenStack Region(s). But if I understand the fault - the migrate/resize/live migrate/rebuild/evacuate will not work because . assuming that on target Compute Host you don't have local disk - and your flavor has more than 0 GB for root and/or ephemeral disk -it would fail. So I would say that setting your root disk space to '0' in the flavor might be a better workaround BR, Konstantin [1] http://lists.openstack.org/pipermail/openstack-dev/2016-August/101566.html [2] https://review.openstack.org/#/c/200870/ [3] https://review.openstack.org/#/c/355091/ > -----Original Message----- > From: William Josefsson [mailto:william.josefson at gmail.com] > Sent: Sunday, August 14, 2016 5:47 PM > To: openstack-operators at lists.openstack.org > Subject: [Openstack-operators] DiskFilter Disabled - No valid host was found > > Hello, I got Error, no valid host was found while trying to provision and I could in > nova-scheduler.log see that the DiskFilter failed to find a compute host.
