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
