Subject: [PATCH] spice: adding seamless-migration option to the command line
|
|
|
|
The seamless-migration flag is required in order to identify
|
|
whether libvirt supports the new QEVENT_SPICE_MIGRATE_COMPLETED or not
|
|
(by default the flag is off).
|
|
New libvirt versions that wait for QEVENT_SPICE_MIGRATE_COMPLETED should turn on this flag.
|
|
When this flag is off, spice fallbacks to its old migration method, which
|
|
can result in data loss.
