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. =3D=3D Version information $ lsb_release -rd Description: Ubuntu 9.04 Release: 9.04 $ apt-cache policy kvm kvm: Installed: 1:84+dfsg-0ubuntu11 Candidate: 1:84+dfsg-0ubuntu11 Version table: *** 1:84+dfsg-0ubuntu11 0 500 http://gb.archive.ubuntu.com jaunty/main Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/391880/+subscriptio= ns
