Both are ZEN gen1. I=E2=80=99m running 8-node PVE7 with ZFS underneath. Without enabling 'non-free=E2=80=99 and installing amd64-microcode (& = reboot) the migration completed successfully, but VM was frozen. No = networking, no console. After installing amd64-microcode, live migration works fine both ways. This wasn=E2=80=99t obvious for me, so just FYI, maybe it saves some = time for somebody :) JV=
