Bug Description
Binary package hint: kvm
Using
migrate "exec:true"
in the monitor hangs the VM for several minutes. What I expect is that the VM stops attempting to migrate after the pipe has been closed.
Indicating a background migrate with -d doesn't help. Presumably the migration is not backgrounded until a certain amount of data is written to the pipe, or the migration times out. What I expect is that the migration is backgrounded immediately.

I can reproduce this in Lucid. Like the other related bug report, I don't have a strong opinion on the feature request, though it seems reasonable. We will defer to Upstream's decision on this one. Thanks!
