Subject: [Qemu-devel] Live Migration with different block devices

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
