I have two host machines on the same subnet, and I have /var/lib/libvirt/images shared between the two via NFS. I'm trying to do a "migration" from one host to another and I'm getting an error.
virsh # migrate --live Narwhal qemu+ssh://10.1.1.1/system error: operation failed: failed to start listening VM
That's from the host running the VM to the new host. I'm assuming you have to do a "push" migrate, not a "pull"? Where can I look next to figure out why it didn't work?
Hum that sounds familiar, what versions of libvirt are you running on both nodes, look at /var/log/libvirt/qemu/Narwhal.log on the target for informations. I suggest to make sure that you get up2date and similar versions on both sides to avoid extra troubles.
Host 1: libvirt-0.6.2-12.fc11.x86_64 Host 2: libvirt-0.6.2-12.fc11.i586
Both machine are 64 bit, Host 2 is just running i386 code. Will that be a problem?
yes that can be a problem !
If I check Narwhal.log there is nothing in there at the time of the migration error. Nothing in messages either. As far as I can tell it just fails silently.
Maybe we need to resurrect the idea of the pre-migration check Also is Narwhal still running on Host 1 after the operation failed, based on the error message I assume the error shows up after a fair amount of time spent sending the domain state between both nodes, right ?
