Some hypervisors require a respawn of the hypervisor to allow reverting
to some snapshot states. This patch adds flag to remove the default
safe approach to not allow this. When this flag is specified the
hypervisor driver should re-emit events to allow management apps to
reconnect.
This flag is
The workhorse part of qemuDomainSaveImageStartVM can be reused while
loading external snapshots. This patch splits the code out into a new
function qemuDomainSaveImageLoad that is free of setting lifecycle

This patch adds support for reverting of external snapshots. The support
is somewhat limited yet (you can only revert to a snapshot that has no
children or delete the children that would have their image chains
invalidated).
While reverting an external snapshot, the domain has to be taken offline
These set bridge part of QoS when bringing domain's interface up.
Long story short, if there's a 'floor' set, a new QoS class is created.
ClassID MUST be unique within the bridge and should be kept for
unplug phase.

This is however supported only on domain interfaces with
type='network'. Moreover, target network needs to have at least
inbound QoS set. This is required by hierarchical traffic shaping.
From now on, the required attribute for inbound/ is either 'average'
(old) or 'floor' (new). This new
Interfaces keeps a class_id, which is an ID from which bridge
part of QoS settings is derived. We need to store class_id
in domain status file, so we can later pass it to
virNetDevBandwidthUnplug.

This will be used whenever a NIC with guaranteed throughput is to

With current implementation, class ID is just incremented. This can
lead to its exhaustion as tc accepts only 16 bits long identifiers.
Hence, it's better if we allow class ID to be reused. To keep track
which IDs are free and which are taken virBitmap is used. This requires
network status file to
Currently, we are only keeping a inactive XML configuration
in status dir. This is no longer enough as we need to keep
this class_id attribute so we don't overwrite old entries
when the daemon restarts. However, since there has already
been a libvirt release which has just network/ as root
This approach implemented in previous patches is not trivial
and deserves small description.
