Re: [Openstack-operators] DiskFilter Disabled - No valid host was found

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

Re: [Openstack-operators] Tuning I/O with SSDs

Re: [Openstack-operators] Mitaka live snapshot of instances not working

Hi, In my previous mail I have indicated the link to website of Kashyap that provides the sequence for cold snapshot and not live snapshot. Could you try the sequence specified in comment ‘Kashyap Chamarthy (kashyapc) wrote on 2014-06-27’ in [1] ? Libvirt API

Re: [Openstack-operators] [Nova] Reconciling flavors and block device mappings

Hi, option 1 (=that's what patches suggest) sounds totally fine. Option 3 > Allow block device mappings, when present, to mostly determine instance packing sounds like option 1+additional logic (=keyword 'mostly') I think I miss to understand the part of 'undermining the purpose of the
