virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.
Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.
To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.
This was introduced in commit 5b75a4, which was first in libvirt-4.4.0.

When processing the inputvol for encryption, we need to handle
the case where the inputvol is encrypted. This then allows for

volume or an output volume of some XML provided type.
Add tests to show the various conversion options when either input
or output is encrypted. This includes when both are encrypted.

In some cases we are checking if the mount namespace is enabled
at two places: one is at the beginning of exported function (e.g.
qemuDomainNamespaceSetupDisk()) and the other is at the beginning
of qemuDomainNamespaceMknodPaths() which is called from the
former function anyway. Then we have some other functions which
rely on the later check solely.
In order to compensate for possibly needless function call,
qemuDomainNamespaceMknodPaths() returns early if @npaths is zero.

Attempting to use a chardev definition like
<serial type='unix'>
<target type='isa-serial'/>
</serial>
correctly results in an error being reported, since the source
path - a required piece of information - is missing; however,
the very similar
<serial type='unix'>
<target type='pci-serial'/>
</serial>
was happily accepted by libvirt, only to result in libvirtd
crashing as soon as the guest was started.
The issue was caused by checking the chardev's targetType
against whitelisted values from virDomainChrChannelTargetType
without first checking the chardev's deviceType to make sure
it is actually a channel, for which the check makes sense,
rather than a different type of chardev.
The only reason this wasn't spotted earlier is that the
whitelisted values just so happen to correspond to USB and
PCI serial devices and Xen and UML consoles respectively,
all of which are fairly uncommon.

Instantiation of an nwfilter binding is only allowed when

teardown of the binding does not make this check. This
leaves open the possibility that the teardown could be

resulting in the following error being logged:
error : nwfilterConnectOpen:383 : internal error: unexpected
