[pve-devel] [PATCH qemu-server v6 05/10] pci: set 'enable-migration' to on for live-migration marked mapped devices

[Dominik Csapak]

the default is 'auto', but for those which are marked as capable for
live migration, we want to explicitly enable that, so we get an early
error on start if the driver does not support that.
