From time to time weird bugreports occur on the list, e.g [1].
Even though the kernel supports setns syscall, there's an older
glibc in the system that misses a wrapper over the syscall.
Hence, after the configure phase we think there's no setns
support in the system, which is obviously wrong. On the other
hand, we can't rely on linux distributions to provide newer glibc
soon. Therefore we need to introduce the wrapper on or own.

When using split UEFI image, it may come handy if libvirt manages per
domain _VARS file automatically. While the _CODE file is RO and can be
shared among multiple domains, you certainly don't want to do that on
the _VARS file. This latter one needs to be per domain. So at the
domain startup process, if it's determined that domain needs _VARS
file it's copied from this master _VARS file. The location of the
master file is configurable in qemu.conf.
Temporary, on per domain basis the location of master NVRAM file can
be overridden by this @template attribute I'm inventing to the
<nvram/> element. All it does is holding path to the master NVRAM file
from which local copy is created. If that's the case, the map in

Up to now, users can configure BIOS via the <loader/> element. With
the upcoming implementation of UEFI this is not enough as BIOS and
UEFI are conceptually different. For instance, while BIOS is ROM, UEFI
is programmable flash (although all writes to code section are
denied). Therefore we need new attribute @type which will
differentiate the two. Then, new attribute @readonly is introduced to
reflect the fact that some images are RO.
Moreover, the OVMF (which is going to be used mostly), works in two
modes:
1) Code and UEFI variable store is mixed in one file.
2) Code and UEFI variable store is separated in two files
The latter has advantage of updating the UEFI code without losing the
configuration. However, in order to represent the latter case we need
yet another XML element: <nvram/>. Currently, it has no additional
attributes, it's just a bare element containing path to the variable
store file.

Total time of a migration and total downtime transfered from a source to

destination host and with the time elapsed before guest CPUs are

guest CPUs were paused. Both timestamps are transferred to destination
libvirtd which uses them to compute total migration time and total
downtime. Obviously, this requires the time to be synchronized between
the two hosts. The reported times are useless otherwise but they would
be equally useless if we didn't do this recomputation so don't lose

Resolve a libvirtd crash in virStoragePoolSourceFindDuplicate()
when there is an existing SCSI pool defined with adapter type as
'scsi_host' and defining a new SCSI pool with adapter type as
'fc_host' and parent attribute missing or vice versa.
For example, if there is an existing SCSI pool with adapter type
as 'scsi_host' defined using the following XML
<pool type='scsi'>
<name>TEST_SCSI_POOL</name>
<source>
<adapter type='scsi_host' name='scsi_host1'/>
</source>
<target>
<path>/dev/disk/by-path</path>
</target>
</pool>
When defining another SCSI pool with adapter type as 'fc_host' using the
following XML will crash libvirtd

<name>TEST_SCSI_FC_POOL</name>

<adapter type='fc_host' wwnn='1234567890abcdef' wwpn='abcdef1234567890'/>
</source>

</target>
</pool>
Same is true for the reverse case as well where there exists a SCSI pool
with adapter type as 'fc_host' and another SCSI pool is defined with
adapter type as 'scsi_host'.
This happens because for fc_host 'name' is optional attribute whereas for
scsi_host its mandatory. However the check in libvirt for finding duplicate
storage pools didn't take that into account while comparing

To date, anyone performing a block copy and pivot ends up with
the destination being treated as <disk type='file'>. While this
works for data access for a block device, it has at least one
noticeable shortcoming: virDomainGetBlockInfo() reports allocation
differently for block devices visited as files (the size of the
device) than for block devices visited as <disk type='block'>
(the maximum sector used, as reported by qemu); and this difference
is significant when trying to manage qcow2 format on block devices
that can be grown as needed.
Of course, the more powerful virDomainBlockCopy() API can already
express the ability to set the <disk> type. But a new API can't
be backported, while a new flag to an existing API can; and it is
also rather inconvenient to have to resort to the full power of
generating XML when just adding a flag to the older call will do
the trick. So this patch enhances blockcopy to let the user flag
when the resulting XML after the copy must list the device as
type='block'.

While reviewing the new virDomainBlockCopy API, Peter Krempa
pointed out that our existing design of using MiB/s for block
job bandwidth is rather coarse, especially since qemu tracks
it in bytes/s; so virDomainBlockCopy only accepts bytes/s.
But once the new API is implemented for qemu, we will be in
the situation where it is possible to set a value that cannot
be accurately reflected back to the user, because the existing
virDomainGetBlockJobInfo defaults to the coarser units.
Fortunately, we have an escape hatch; and one that has already
served us well in the past: we can use the flags argument to
specify which scale to use (see virDomainBlockResize for prior
art). This patch fixes the query side of the API; made easier
by previous patches that split the query side out from the
modification code. Later patches will address the virsh
interface, as well retrofitting all other blockjob APIs to
also accept a flag for toggling bandwidth units.

qemu treats blockjob bandwidth as a 64-bit number, in the units
of bytes/second. But we stupidly modeled block job bandwidth
after migration bandwidth, which in turn was an 'unsigned long'
and therefore subject to 32-bit vs. 64-bit interpretations, and
with a scale of MiB/s. Our code already has to convert between
the two scales, and report overflow as appropriate; although
this conversion currently lives in the monitor code. In fact,
our conversion code limited things to 63 bits, because we
checked against LLONG_MAX and reject what would be negative
bandwidth if treated as signed.
On the bright side, our use of MiB/s means that even with a
32-bit unsigned long, we still have no problem representing a
bandwidth of 2GiB/s, which is starting to be more feasible as
10-gigabit or even faster interfaces are used. And once you
get past the physical speeds of existing interfaces, any larger
bandwidth number behaves the same - effectively unlimited.
But on the low side, the granularity of 1MiB/s tuning is rather
coarse. So the new virDomainBlockJob API decided to go with
a direct 64-bit bytes/sec number instead of the scaled number
that prior blockjob APIs had used. But there is no point in
rounding this number to MiB/s just to scale it back to bytes/s
for handing to qemu.
In order to make future code sharing possible between the old
virDomainBlockRebase and the new virDomainBlockCopy, this patch
moves the scaling and overflow detection into the driver code.
Several of the block job calls that can set speed are fed
through a common interface, so it was easier to adjust all block
jobs at once, for consistency. This patch is just code motion;
there should be no user-visible change in behavior.

There are two ways in which security model can make it way into
<seclabel/>. One is as the @model attribute, the second one is
via security_driver knob in qemu.conf. Then, while parsing
<seclabel/> several checks and fix ups of old, stale combinations
are performed. However, iff @model is specified. They are not
done in the latter case. So it's still possible to feed libvirt
with senseless combinations (if qemu.conf is adjusted correctly).
One example of a seclabel that needs some adjustment (in case
security_driver=none in qemu.conf) is:

The qemu implementation for virDomainGetBlockJobInfo() has a
minor bug: it grabs the qemu job with intent to QEMU_JOB_MODIFY,
which means it cannot be run in parallel with any other
domain-modifying command. Among others, virDomainBlockJobAbort()
is such a modifying command, and it defaults to being
synchronous, and can wait as long as several seconds to ensure
that the job has actually finished. Due to the job rules, this
means a user cannot obtain status about the job during that
timeframe, even though we know that some client management code
exists which is using a polling loop on status to see when a job
finishes.
This bug has been present ever since blockpull support was first
introduced (commit b976165, v0.9.4 in Jul 2011), all because we
stupidly tried to cram too much multiplexing through a single
helper routine, but was made worse in 97c59b9 (v1.2.7) when
BlockJobAbort was fixed to wait longer. It's time to disentangle
some of the mess in qemuDomainBlockJobImpl, and in the process
relax block job query to use QEMU_JOB_QUERY, since it can safely
be used in parallel with any long running modify command.
Technically, there is one case where getting block job info can
modify domain XML - we do snooping to see if a 2-phase job has
transitioned into the second phase, for an optimization in the
case of old qemu that lacked an event for the transition. I
claim this optimization is safe (the jobs are all about modifying
qemu state, not necessarily xml state); but if it proves to be
a problem, we could use the difference between the capabilities
QEMU_CAPS_BLOCKJOB_{ASYNC,SYNC} to determine whether we even
need snooping, and only request a modifying job in the case of
older qemu.

The existing virDomainBlockRebase code rejected the combination of
_RELATIVE and _COPY flags, but only by accident. It makes sense
to add support for the combination someday, at least for the case

have to pre-create the file with a relative backing name, and I'm
not ready to code that in yet.
Meanwhile, the code to forward on to the block copy code is getting
longer, and reorganizing the function to have the block pull done
early makes it easier to add even more block copy prep code.
