Public bug reported:
virsh migration copy-storage-all fails with "Unable to read from
monitor: Connection reset by peer" and shut downs the guest on the
source host.
Kernel Version: 3.10.0-rc5+
Libvirt Version: 1.0.6
Qemu Version: 1.5.50
Steps to reproduce the issue:
----------------------------------------
1. Created the qemu-img create -f qcow2 vm.qcow2 11G on the destination host
which is same as the source.
2. Started the guest on the source
3. Started the vncdisplay to monitor the guest
4. Initiated the migration "virsh migrate --live VM1 qemu+ssh://host-ip/system
tcp://host-ip --verbose --copy-storage-all"
5. It started the copying the storage from souce to destination (conitinously
monitored it was growing)
6. Guest on the destination was paused and was running on the source
7. At some point the VM on the source got shutdown and migration failed with
"Unable to read from monitor: Connection reset by peer"
Attached the libvirt debug logs.
The debug logs shows :
2013-06-19 08:43:12.253+0000: 4026: debug : virEventPollInterruptLocked:716 :
Interrupting
2013-06-19 08:43:12.253+0000: 4026: debug : virEventPollAddTimeout:248 :
EVENT_POLL_ADD_TIMEOUT: timer=1 frequency=0 cb=0x7fe930baa960 opaque=(nil)
ff=(nil)
Note: The virsh live migration works fine with nfs storage from source to
destination and vice versa.
With libvirt 1.0.5 and qemu 1.5 also we were facing the same issue, but with
that even "Live migration with nfs also was not working".
