Hi,

I have a Windows system which fails to migrate with this error almost reliably when migrating
from one host to another (both qemu-2.2.0). The error seems to be gone in master, but I was
unable to track the exact fix down yet. It seems that the error is related to the amount of
memory. 4G and 8G seem to fail. 3G and 6G seem to work.

Any hints?

Commandline:

x86_64-softmmu/qemu-system-x86_64 -enable-kvm -monitor stdio -M pc-i440fx-2.1   -nodefaults  -device virtio-net-pci,mac=52:54:00:ff:09:7a  -global virtio-blk-pci.scsi=off  -serial null  -parallel null -smp 2,sockets=1,cores=2,threads=1   -name

Thanks,
