When an interface has some bandwidth limitation set (it's root
qdisc is htb in that case) but this gets cleared out via public
API call (virDomainSetInterfaceParameters() or
virDomainUpdateDeviceFlags()) then virNetDevBandwidthSet() clears
out whatever qdiscs were set on the interface and kernel places
the default qdisc at the root. What we need to do next is to
replace the root qdisc with the one we want.

While the code that's setting default qdisc is clever enough to
not overwrite any bandwidth (potentially) set by
virNetDevBandwidthSet() (and thus the root qdisc htb is not
replaced with noqueue), it does print a debug message when that's
the case. It's needless. We can set the root qdisc beforehand and
let virNetDevBandwidthSet() overwrite it.

Some secdrivers (typically SELinux driver) generate unique
dynamic seclabel for each domain (unless a static one is
requested in domain XML). This is achieved by calling
qemuSecurityGenLabel() from qemuProcessPrepareDomain() which
allocates unique seclabel and stores it in domain def->seclabels.
The counterpart is qemuSecurityReleaseLabel() which releases the
label and removes it from def->seclabels. Problem is, that with
current code the qemuProcessStop() may still want to use the
seclabel after it was released, e.g. when it wants to restore the
label of a disk mirror.
What is happening now, is that in qemuProcessStop() the
qemuSecurityReleaseLabel() is called, which removes the SELinux
seclabel from def->seclabels, yada yada yada and eventually
qemuSecurityRestoreImageLabel() is called. This bubbles down to
virSecuritySELinuxRestoreImageLabelSingle() which find no SELinux
seclabel (using virDomainDefGetSecurityLabelDef()) and this
returns early doing nothing.

Currently, we configure QEMU to prealloc memory almost by
default. Well, by default for NVDIMMs, hugepages and if user
asked us to (via memoryBacking <allocation mode="immediate"/>).
However, when guest's NVDIMM is backed by real life NVDIMM this
approach is not the best. In this case users should put <pmem/>
into the <memory/> device <source/>, like this:
<memory model='nvdimm' access='shared'>
<source>
<path>/dev/pmem0</path>
<pmem/>
</source>
</memory>
Instructing QEMU to do prealloc in this case means that each
page of the NVDIMM is "touched" (the first byte is read and
written back - see QEMU commit v2.9.0-rc1~26^2) which cripples
device wear.
