Hi,
When I do live migration, in the source and destination host, there are
different block devices, but qemu can not detect this. I used virtio as the
driver in kvm and in the vdi device in the guest is /dev/vda. So, the vm
guest can read different data from the same /dev/vda device. I am studying
this code to let qemu understand that, this is a new device.
Does qemu recognize different block devices after live migration? Where is
the interface to modify this? Thanks
Gary
