Little Migrate Bug in combination with Snapshots?

[rengiared]

hi

at the moment i have a new test-environment with 3 old-workstations where i'm playing with ceph (there are a few questions left, but they belong to another thread)

So i have a VM with a fresh installed windows 7 and took a snapshot.
in the meantime i ejected the win7 intalldisc and did a few tests and installs.

now i wanted to test the live-migration from one host to another and got this error:



after whondering why and how this appears i looked into the config-file and got it, cause in the snapshot information the iso is still deposited.

bootdisk: ide0
cores: 2
ide0: ceph-test:vm-100-disk-1,size=32G
ide2: none,media=cdrom
memory: 2048

net0: e1000=0A:E9:7E:73:F2:18,bridge=vmbr0

after editing the config file to "ide2: none,media=cdrom" the migration went through (like a charm even on my low-power test environment, zero loss, just one high ping with about 1000ms! really great)

i don't know how you guys rate this behaviour but i would but a "bug-sticker" on it.
not a big problem cause you can solve it in seconds when you know why, but it took me a few minutes to find out why.

thx and keep up the great work, next thing for me is HA in combination with CEPH

that's not a bug.
iso files mounted on a non shared storage (e.g local disk) cannot be live migrated to another cluster node.

it was mounted at the time the snapshot was taken, but at the time of the migration there was nothing mounted, thats the point i think it's a bug
it will even fail when the iso was on a shared storage but isn't there anymore, cause it' already deleted or whatever
maybe i'm the only one who thinks that at the migration only the actual state should be considered and not maybe a 2 year old snapshot where an image was mounted
