Hello, Qemu version 5.1 host os Debian 10.7 Two exactly the same machines ( except ram size 380G and 1.5T ) Live migration fails (from host with 380G ram to 1.5T) with errors like this: Feb 02 16:26:13 QEMU[12090]: kvm: load of migration failed: Invalid argument Feb 02 16:26:13 QEMU[12090]: kvm: error while loading state for instance 0x0 of device 'ram' Feb 02 16:26:13 QEMU[12090]: kvm: Mismatched RAM page size ram-node0 (local) 2097152 != 1526773257204281392 I think it's some overflow issue. -- Thanks, Damir Chanyshev
