77c9663d72 qemu: add support for librbd layered encryption
This commit enables libvirt users to use layered encryption
of RBD images, using the librbd encryption engine.
This allows opening of an encrypted cloned image
whose parent is encrypted with a possibly different encryption key.
To open such images, multiple encryption secrets are expected
to be defined under the encryption XML tag.

b1b037fa5b Introduce VIR_DOMAIN_PAUSED_API_ERROR
Some APIs (migration, save/restore, snapshot, ...) require a domain to
be suspended temporarily. In case resuming the domain fails, the domain
will be unexpectedly left paused when the API finishes. This situation
is reported via VIR_DOMAIN_EVENT_SUSPENDED event with
VIR_DOMAIN_EVENT_SUSPENDED_API_ERROR detail. But we do not have a
corresponding reason for VIR_DOMAIN_PAUSED state and the reason would
remain set to the value used when the domain was paused. So the state
reason would suggest the operation is still running.

This patch changes the state reason to a new VIR_DOMAIN_PAUSED_API_ERROR
to make it clear the API that paused the domain already finished, but
failed to resume the domain.

Currently it's only possible to set this parameter during domain
creation via QEMU commandline passthrough feature.
With the new delay attribute it's also possible to set this
parameter if you want to attach a new NBD disk
using "virsh attach-device domain device.xml" e.g.:

  <disk type='network' device='disk'>
    <driver name='qemu' type='raw'/>
    <source protocol='nbd' name='foo'>
      <host name='example.org' port='6000'/>

Add the ability to enable blob resources for the virtio video device.
This will accelerate the display path due to less or no copying of pixel

Blob resource support can be enabled with e.g.:

172dd3d9f7 conf: Make macvtap ethernet share host view
When fetching stats for a domain's <interface/>, or when setting
up its QoS, we can face two situations:

1) the device "shares" the host view, meaning each packet
   sent/received on the interface by a domain is accounted for in
   the same category on the host, or

2) the device is at the other side, and a packet send by a
   domain, is in fact packet received on the host.

This fact affects whether we need to swap RX/TX values when
fetching stats, or setting up QoS. We have this convenient helper
function (virDomainNetTypeSharesHostView()), which returns to
which category given interface type falls into.

Now, for unmanaged type='ethernet' our options are quite limited,
because it's user's responsibility to set up the host side of the
interface. And it can be just anything. Fortunately, we have
another convenience function (virNetDevMacVLanIsMacvtap()), which
determines whether given interface is a macvtap (which is
notoriously known for falling into the first category).
Let's use it to help virDomainNetTypeSharesHostView() determine
the view more accurately.

reasonable: loader->nvramTemplate is stored separately, so if

However, this is about to change, so we will find ourselves
needing to hold on to loader->nvram even when no path is
present. Change the firmware handling code so that such a
