From fe341d97aee2666dc378f89de4a957bc8ae35a21 Mon Sep 17 00:00:00 2001

Subject: [PATCH] virt-manager: enable MDEV support
Enable virt-manager GUI to support add, edit, remove, hot-plug and
hot-unplug of mediated devices (like DASDs, APQNs and PCIs) in virtual
server.
It is not possible to edit MDEV when a virtual server is in
running state, as this is not supported by libvirt.

Subject: [PATCH] virt-xml: add support for mediated devices
Provide support to add/remove MDEV in a guest domain, which is in
shut-off or running state (hotplug/unplug). Also support update of
already existing MDEV device, when the guest domain is in shut-off
state. Please note that libvirt does not support update of MDEV
device, when the guest domain is in running state.
