Subject: [PATCH] virt-xml: add support for mediated devices
|
|
|
610fa1 |
|
|
|
610fa1 |
Provide support to add/remove MDEV in a guest domain, which is in
|
|
|
610fa1 |
shut-off or running state (hotplug/unplug). Also support update of
|
|
|
610fa1 |
already existing MDEV device, when the guest domain is in shut-off
|
|
|
610fa1 |
state. Please note that libvirt does not support update of MDEV
|
|
|
610fa1 |
device, when the guest domain is in running state.
