Public bug reported:
We're trying to live migrate machine "fhdhvalentijn" to a server named "ranja".
This used to work perfectly when both systems ran 12.04 Precise. After
upgrading the target machine ("ranja") to Trusty, migration fails; sometimes,
migration results in shutting down the VM.
Command: virsh migrate --live --copy-storage-all --verbose vhdhvalentijn
qemu+ssh://ranja/system
Expected: live migration
Result: "error: operation failed: migration job: unexpectedly failed"
Logfile on server "Ranja" says:
Length mismatch: vga.vram: 1000000 in != 800000
qemu: warning: error while loading state for instance 0x0 of device 'ram'
load of migration failed
2014-03-12 11:05:30.325+0000: shutting down
Logfile on server "Duikboot" (the host) sometimes suddenly says:
"2014-03-12 11:18:25.645+0000: shutting down" and then the VM is no
longer running.
I also tried to start the migration from 14.04 (virsh -c
qemu+ssh://duikboot/system migrate --live --copy-storage-all ...), and
also tried to leave out "--live" (and tried various options like
migrating with virt-manager). Also tried to migrate a "virgin" machine
(i.e. a newly created machine with default options) - to no avail.
I did not try to migrate directly with qemu - as I have no experience
with that.
