Hello.
Hi,
I have two servers between which I need have live migration.
First server have QEMU emulator version 2.3.0
Second server have QEMU emulator version 2.5.0
Migration command look like this:
/usr/bin/virsh migrate --live DOMAIN_NAME --migrateuri
tcp://second.server
qemu+ssh://second.server/system --verbose
I got next error on console:
error: operation failed: migration job: unexpectedly failed
And next error in log on second server:
2016-01-11T15:07:12.888647Z qemu-system-x86_64: Length too large:
/rom@genroms/efi-virtio.rom: 0x32000 > 0x2d000: Invalid argument

2016-01-11T15:07:12.889733Z qemu-system-x86_64: load of migration

Invalid argument
In my libvirt domain I have option <rom bar="off"/>.
I need to do a live migration in any possible way. How can I do this
one?
Is the efi-virtio ROM that you're using on the two versions the same
identical size?
No, I have different efi-virtio.rom files, and I try to find a way which
allows me not to copy the same efi-virtio.rom to all servers.
Also, can you post the commandline that you're using please.
I already done this in my first email: virsh migrate...
/usr/bin/virsh migrate --live DOMAIN_NAME --migrateuri
tcp://second.server
qemu+ssh://second.server/system --verbose
Regards,
Alexey Mochkin.
