(virStorageEncryptionSecret, virStorageEncryption): Directly use
enums.

One caveat though, qemu-ga is expecting time and returning time
in nanoseconds. With all the buffering and propagation delay, the
time is already wrong once it gets to the qemu-ga, but there's
nothing we can do about it.

These APIs allow users to get or set time in a domain, which may come
handy if the domain has been resumed just recently and NTP is not
configured or hasn't kicked in yet and the guest is running
something time critical. In addition, NTP may refuse to re-set the clock
if the skew is too big.
In addition, new ACL attribute is introduced 'set_time'.

For now, if only '--wipe-storage' is assigned, user can undefine a
domain normally. But actually '--wipe-storage' doesn't do anything,
and this may confuse user. Better is to require that '--wipe-storage'
only works if the user specifies volumes to be removed.

$ virsh undefine virt-tests-vm1 --wipe-storage

When qemu driver is polling for migration to finish (in
qemuMigrationWaitForCompletion), it may happen that another job allowed
during migration is running and if it does not finish within 30 seconds,
migration would be cancelled because of that. However, we can just
ignore the timeout and let the waiting loop try again later.
If an event fired at the end of migration is ever implemented in QEMU,
we can just wait for the event instead of polling for migration status
and libvirt will behave consistently, i.e., migration won't be cancelled
in case another job started during migration takes long time to finish.

If job queue is full or waiting for a job times out, the function

Move sharable PCI handling functions to domain_addr.[ch], and
change theirs prefix from 'qemu' to 'vir':
- virDomainPCIAddressAsString;
- virDomainPCIAddressBusSetModel;
- virDomainPCIAddressEnsureAddr;
- virDomainPCIAddressFlagsCompatible;
- virDomainPCIAddressGetNextSlot;
- virDomainPCIAddressReleaseSlot;
- virDomainPCIAddressReserveAddr;
- virDomainPCIAddressReserveNextSlot;
- virDomainPCIAddressReserveSlot;
- virDomainPCIAddressSetFree;
- virDomainPCIAddressSetGrow;
- virDomainPCIAddressSlotInUse;
- virDomainPCIAddressValidate;
The only change here is function names, the implementation itself
stays untouched.
Extract common allocation code from DomainPCIAddressSetCreate
into virDomainPCIAddressSetAlloc.
Introduce new files (domain_addr.[ch]) to provide
an API for domain device handling that could be
shared across the drivers.
A list of data types were extracted and moved there:
qemuDomainPCIAddressBus -> virDomainPCIAddressBus
qemuDomainPCIAddressBusPtr -> virDomainPCIAddressBusPtr
_qemuDomainPCIAddressSet -> virDomainPCIAddressSet
qemuDomainPCIAddressSetPtr -> virDomainPCIAddressSetPtr
qemuDomainPCIConnectFlags -> virDomainPCIConnectFlags
Also, move the related definitions and macros.

If qemuDomainBlockResize() is passed a size not on a KiB boundary - that
is passed a size based in bytes (VIR_DOMAIN_BLOCK_RESIZE_BYTES), then
depending on the source format (qcow2 or qed), the value passed must
be on a sector (or 512 byte) boundary. Since other libvirt code quietly
adjusts the capacity values, then do so here as well.
Commit 9976c4b9a6 broke the output for VNC
displays as the port number is converted to VNC display number by
subtracting 5900. This yields port 0 for the first display and thus the
output would be skipped.
Before:
$ virsh domdisplay VM
vnc://localhost
After:
$ tools/virsh domdisplay VM

When a domain was started without registration in sanlock, but libvirt
was restarted after that, most of the operations failed due to
contacting sanlock about that process. E.g. migration could not be
performed because the locks couldn't be released (or inquired before a

Our documentation generator is a bit messy, to say the least. For
instance, the description to return values of a function is
searched within C comment. Currently, all lines that start with
'returns' or 'Returns' are viewed as return value description.
However, there are some valid uses where the 'returns' word is in
the middle of a sentence describing function behavior not the
return value. And there are no places where 'returns' is used to
describe return values. For instance:
virDomainDetachDeviceFlags, virConnectNetworkEventRegisterAny and
virDomainGetDiskErrors. This leads to HTML documemtation being
generated incorrectly.

There is a problem with function parallelsDomainDefineXML. If we
are defining a new domain, then we need to do 2 things: aclually
create a VM in PCS and add new domain to the cached list of domains
_parallelsConn.domains.
This is done in the function parallelsLoadDomains. So call to
virDomainObjListAdd will return a error, because a domain
with the same name and id will already be in the list.

I added this code year ago, instead of implementing ability
to change VNC configuration, which was not trivial, I added
extra call to prlctl, which sets up VNC with auto port, despite
VNC configuration given by a user.
Let's remove this hack, because, first, it doesn't work on the
latest Parallels Cloud Server release (you have to either specify
--vnc-nopasswd option or password). And also has problem with
error handling. If second call to prlctl fails, VM, created by
first call to prlctl, will not be removed.

FSFreeze is requested in the domain.
It modifies error code from qemuDomainSnapshotFSFreeze and

freeze command, a counterpart thaw command shouldn't be sent either, not to
