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.
