Hello:
It seems that, running VMs with multiple disks attached to it, require that the disks have cache setting to ‘none’ for the live migration to work. Is there a way to change/update the disk cache settings of disks that are already attached to running VMs?
Thank you,
-Robert
Sorry there is no direct way to do so
It seems the way around this is to specify the --unsafe flag in the live-migration. I only feel ok doing this because all disks that were previously attached to VMs, did not have any cache specification at all, so i assume the default with no cache specification also = none. It just wasn’t explicitly selected as ‘none’ so its not recorded as such, causing it to complain.
