From: "Dr. David Alan Gilbert" <dgilb...@redhat.com>
Update 'info migrate' to display migration blocking information.
If the outbound migration is not blocked, there is no change, however
if it is blocked a message is displayed with a list of reasons why,
e.g.
qemu-system-x86_64 -nographic -smp 4 -m 4G -M pc,usb=on \
-chardev null,id=n -device usb-serial,chardev=n \
-virtfs local,path=/home,mount_tag=fs,security_model=none \
-drive if=virtio,file=myimage.qcow2
(qemu) info migrate
globals:
store-global-state: on
only-migratable: off
send-configuration: on
send-section-footer: on
decompress-error-check: on
clear-bitmap-shift: 18
Outgoing migration blocked:
Migration is disabled when VirtFS export path '/home' is mounted in the guest
using mount_tag 'fs'
non-migratable device: 0000:00:01.2/1/usb-serial
