An follow up questions.
Suppose I have a running VM with two virtual disks, I would like to migrate the vm from host A to host B. Both host A and host B have their own isolated storage devices. Is there anyway to migrate the vm's memory, two virtual disk images and other states together from host A to host B? Can drive_mirror command itself finish this job? I noticed that drive_mirror only mirror for one virtual disk and require both the source and destination share the same storage namespace. I do not know how to migrate the whole VM (memory, storage, network ) together from host A to host B, given that host A and host B have NO shared storage resource.
Could you show me an example, if possible?
I know "migrate -b" works well for this purpose. But the downside is "migrate -b" does not mirror Write Requests to both host A and host B during migration. In this case, "migrate -b" has a higher VM downtime during the migration.
