Hi All, I couldn't find any mention about live migration incompatibility between 5.0 and 5.1 in the release notes but at least on our AMD based platform live migration from 5.0 to 5.1 is not possible.
The upgraded host had identical versions with it's pair before the upgrade was started: * qemu 5.0.0-r2 * kernel 5.7.17 After upgrade: * qemu 5.1.0-r1 * kernel 5.8.16 After reverting qemu back to 5.0.0-r2 migration worked normally. On the sending end "info migrate" shows: (qemu) info migrate info migrate globals: store-global-state: on only-migratable: off send-configuration: on send-section-footer: on decompress-error-check: on clear-bitmap-shift: 18 Migration status: failed (Unable to write to socket: Broken pipe) total time: 0 milliseconds At least once the receiving end died (while running 5.1.0-r1). All attempts resulted a "Broken pipe" error on the sending (5.0.0-r2) end. Cheers, Antti -- Antti Antinoja <rea...@fennosys.fi>
