Hi,
No, it's not a persistent disk. It's just a regular OS image.
Yes - it doesn't get copied to the other nebula host. But it seems like
it doesn't even try to copy the image. The live migration error shows
almost immediately. And the vm keeps running on the original host.
I'm not entirely sure if it's nebula's job to copy the image, or is it
Xen's job..?
And the other - cold migration - it doesn't work either.. :(
It copies the image and the checkpoint file to the other host, but then
when it tries to boot the VM I get the error below..
Cheers,
J

It looks that it can not find a image file:

/var/lib/one//datastores/0/28/disk.0 does not exist.
Is that image a persistent disk? In that case, is it located in a
shared datastore that is not mounted in that host?
Cheers

Hi,
I have a problem with migrating VMs between hosts. Both cold and live
