I have two KVM host, and suddenly the live migration fails with this error message:

Migration: [100 %]error: internal error: qemu unexpectedly closed the monitor: 2018-10-23T10:15:25.737813Z qemu-system-x86_64: -chardev pty,id=charserial0: char device redirected to /dev/pts/22 (label charserial0)

2018-10-23T10:18:51.902790Z qemu-system-x86_64: load of migration failed: Invalid argument

The source node has:
-4.18.6 kernel
-2.12.1 qemu

The destination node has:
-4.8.8 kernel
-2.12.1 qemu

What could cause this problem?

Thank you for help :)
