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.

If leasehelper fails all that we are left with is a simple error
message produced by dnsmasq:
lease-init script returned exit code 1
This is because the leasehelper did not write any message to
stderr. According to dnsmasq's manpage, whenever it's invoking
leasehelper the stderr is kept open:
All file descriptors are closed except stdin, which is open to
/dev/null, and stdout and stderr which capture output for
logging by dnsmasq.
As debugging leasehelper is not trivial (because dnsmasq invokes
it with plenty of env vars set - that's how data is passed onto
helper), let's print an error into stderr if exiting with an
error. And since we are not calling public APIs, we have to call
virDispatchError() explicitly and since we don't have any
connection open, we have to pass NULL.
