Bhyve as of r279225 (FreeBSD -CURRENT) or r284894 (FreeBSD 10-STABLE)
supports using UTC time offset via the '-u' argument to bhyve(8). By
default it's still using localtime.
Make the bhyve driver use UTC clock if it's requested by specifying
<clock offset='utc'> in domain XML and if the bhyve(8) binary supports
the '-u' flag.
When cleaning up the data (taken from a running system) for inclusion
I went a little too far and deleted a bunch of links that should have
been left alone. The test worked despite this because it was going
through a fallback code path.
A few other files are affected as well: again, the data is taken from
a running system, so even thought we would probably be okay if we
just added the links, aligning everything is definitely safer.
The scope name, even according to our docs is
"machine-$DRIVER\x2d$VMNAME.scope" virSystemdMakeScopeName would use the
resource partition name instead of "machine-" if it was specified thus
creating invalid scope paths.
This makes libvirt drop cgroups for a VM that uses custom resource
partition upon reconnecting since the detected scope name would not
match the expected name generated by virSystemdMakeScopeName.
The error is exposed by the following log entry:
debug : virCgroupValidateMachineGroup:302 : Name 'machine-qemu\x2dtestvm.scope' for controller 'cpu' does not match 'testvm', 'testvm.libvirt-qemu' or 'machine-test-qemu\x2dtestvm.scope'

Some of the possible CPUs in a system might not be present, eg. they

The formatdomain.html description for <disk> device 'lun' indicates that

So far the argument has not much meaning and was practically ignored.
This is not good since when doing memory hotplug, the size of desired
hugepage backing is passed in that argument. Taking closer look at the
tests I'm fixing reveals the bug. For instance, while the following is
in the test:
<memory model='dimm'>
<source>
<nodemask>1-3</nodemask>
<pagesize unit='KiB'>4096</pagesize>
</source>
<target>
<size unit='KiB'>524287</size>
<node>0</node>
</target>
<address type='dimm' slot='0' base='0x100000000'/>
</memory>
the generated commandline corresponding to this XML was:
-object memory-backend-ram,id=memdimm0,size=536870912,\
host-nodes=1-3,policy=bind
Have you noticed? Yes, memory-backend-ram! Nothing can be further away
from the right answer. The hugepage backing is requested in the XML
and we happily ignore it. This is just not right. It's
memory-backend-file which should have been used:
-object memory-backend-file,id=memdimm0,prealloc=yes,\
mem-path=/dev/hugepages4M/libvirt/qemu,size=536870912,\
host-nodes=1-3,policy=bind
The problem is, that @pagesize passed to qemuBuildMemoryBackendStr
(where this part of commandline is built) was ignored. The hugepage to
back memory was searched only and only by NUMA nodes pinning. This
works only for regular guest NUMA nodes.
Then, I'm changing the hugepages size in the test XMLs too. This is
simply because in the test suite we create dummy mount points just for
2M and 1G hugepages. And in the test 4M was requested. I'm sticking to
2M, but 1G should just work too.

Yajl 2 has a nice feature that it can be configured whether to

valid JSON object was parsed. But we target RHEL 6 yajl 1.0.7,

Commit ceb496e5 fails on RHEL 6, with yajl 1.0.7, because that
version of yajl returns yajl_status_insufficient_data when the
parser is waiting for the rest of a token (this enum value was
dropped in yajl 2, so we have to wrap it). It also exposes a
problem where older yajl silently ignores trailing garbage after
a successful parse, so this patch works around that by changing
the testsuite. Another more invasive patch can add tighter
semantics to json parsing, but this is sufficient for a minimal
clean backport.
While touching this, fix up our error message cleanup. Yajl
documents that error messages produced by yajl_get_error()
MUST be cleaned with yajl_free_error(); this is certainly
true if we were to pass non-NULL allocator callbacks during
yajl_alloc(), but probably harmless in our usage of passing
NULL. But better safe than sorry.

Defining a domain with a SCSI disk attached via a hostdev
tag and a source address unit value longer than two digits
causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest
error: XML document failed to validate against schema:
Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content
The virt-xml-validate tool fails with a similar error:
# virt-xml-validate lmb_guest.xml
Relax-NG validity error : Extra element devices in interleave
lmb_guest.xml:17: element devices: Relax-NG validity error :
Element domain failed to validate content
lmb_guest.xml fails to validate
The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

</hostdev>
...trimmed...
Since the reference unit and target fields are used in
several places in the XML schema, create a separate one
specific for SCSI Logical Units that will permit the
greater length. This permits both the validation utility
and the virsh edit command to succeed when a hostdev
tag is included.

virSocketAddrGetRange() has been updated to take the network address
and prefix, and now checks that both the start and end of the range
are within that network, thus validating that the entire range of
addresses is in the network. For IPv4, it also checks that ranges to
not start with the "network address" of the subnet, nor end with the
broadcast address of the subnet (this check doesn't apply to IPv6,
since IPv6 doesn't have a broadcast or network address)
Negative tests have been added to the network update and socket tests
to verify that bad ranges properly generate an error.
This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=985653
This was revealed when I made a cut-paste mistake in an upgrade to
virSocketAddrGetRange(), leading to failure to check for the end
address being outside of the defined network, but a negative test case
that should have caught the error instead returned success.
The problem was that testRange in sockettest.c was written so that
when it expected a failure, even an "unexpected success" would be
considered as an "expected failure" because of the way the check in
testRange was done. testRange had this:
if (gotsize < 0 || gotsize != size) {
return pass ? -1 : 0;
} else {
return pass ? 0 : -1;
}
but all the tests that expected a failure give "-1" as the expected
size. So in a case where we expect a failure, we would have pass ==
false and size == -1. If virSocketAddrGetRange() was incorrectly
*successful* (returned some positive number), then "gotsize != size"
would be, e.g. "276 != -1", so we would take the if clause and, since
pass == false, we would return 0 (success i.e. expected failure).
The solution is that in the case where we expect failure, we should
just ignore size - virSocketAddrGetRange() must return -1 in order for
us to report "expected failure == success".

can't be configured, so report an error if an address has been
provided in the XML.

The XML parser sets a default <mode> if none is explicitly passed in.
This is then used at pool/vol creation time, and unconditionally reported
in the XML.
The problem with this approach is that it's impossible for other code
to determine if the user explicitly requested a storage mode. There
are some cases where we want to make this distinction, but we currently
can't.
Handle <mode> parsing like we handle <owner>/<group>: if no value is
passed in, set it to -1, and adjust the internal consumers to handle
it.
As of netcf-0.2.8, netcf supports configuring multipl IPv4 addresses,
as well as simultaneously configuring dhcp and static IPv4 addresses,
on a single interface. This patch updates libvirt's interface.rng to
allow such configurations.

Due to a kernel commit (b4b8f770e), cpuinfo format has changed on
ARMs. Firstly, 'Processor: ...' may not be reported, it's
replaced by 'model name: ...'. Secondly, the "Processor" string
may occur in CPU name, e.g. 'ARMv7 Processor rev 5 (v7l)'.
Therefore, we must firstly look for 'model name' and then for
'Processor' if not found.
Moreover, lines in the cpuinfo file are shuffled, so we better
not manipulate the pointer to start of internal buffer as we may
lost some info.

Implementation is pretty straight-forward. Of course, not all qemus
out there supports the device, so new capability is introduced and

Like usb-serial, the pci-serial device allows a serial device to be
attached to PCI bus. An example XML looks like this:
<serial type='dev'>
<source path='/dev/ttyS2'/>
<target type='pci-serial' port='0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</serial>

After parsing the memory device XML the function would not restore the
XML parser context causing invalid XPath starting point for the rest of
the elements. This is a regression since 3e4230d2.
The test case addition uses the <idmap> element that is currently unused
by qemu, but parsed after the memory device definition and formatted
always.

From xl.cfg950 man page:
spiceagent_mouse=BOOLEAN
Whether SPICE agent is used for client mouse mode. The default is
true (1) (turn on)
spicevdagent=BOOLEAN
Enables spice vdagent. The Spice vdagent is an optional component for
enhancing user experience and performing guest-oriented management
tasks. Its features includes: client mouse mode (no need to grab
mouse by client, no mouse lag), automatic adjustment of screen
resolution, copy and paste (text and image) between client and domU.
It also requires vdagent service installed on domU o.s. to work.
The default is 0.
spice_clipboard_sharing=BOOLEAN
Enables Spice clipboard sharing (copy/paste). It requires spicevdagent
enabled. The default is false (0).
So if spiceagent_mouse is enabled (client mouse mode) or
spice_clipboard_sharing is enabled, spicevdagent must be enabled.
Along with this change, s/spicedvagent/spicevdagent, set
spiceagent_mouse correctly, and add a test for these spice
features.

The logic related to spicedisable_ticketing and spicepasswd was
inverted. As per man xl.cfg(5), 'spicedisable_ticketing = 1'
means no passwd is required. On the other hand, a passwd is
required if 'spicedisable_ticketing = 0'. Fix the logic and
produce and error if 'spicedisable_ticketing = 0' but spicepasswd
is not provided. Also fix the spice cfg test file.

We have previously effectively ignored all <controller type='ide'>
elements in a domain definition.
On the i440fx-based machinetypes there is an IDE controller that is
included in the chipset and can't be removed (which is the ide
controller with index='0'>), so it makes sense to ignore that one
controller. However, if an i440fx domain definition has a 2nd
controller, nothing catches this error (unless you also have a disk
attached to it, in which case qemu will complain that you're trying to
use the ide controller named "ide1", which doesn't exist), and if any
other type of domain has even a single controller defined, it will be
incorrectly ignored.
Ignoring a bogus controller definition isn't such a big problem, as
long as an error is logged when any disk is attached to that
non-existent controller. But in the case of q35-based machinetypes,
the hardcoded id ("alias" in libvirt terms) of its builtin SATA
controller is "ide", which happens to be the same id as the builtin
IDE controller on i440fx machinetypes. So libvirt creates a
commandline believing that it is connecting the disk to the builtin
(but actually nonexistent) IDE controller, qemu thinks that libvirt
wanted that disk connected to the builtin SATA controller, and
everybody is happy.
Until you try to connect a 2nd disk to the IDE controller. Then qemu
will complain that you're trying to set unit=1 on a controller that
requires unit=0 (SATA controllers are organized differently than IDE
controllers).
After this patch, if a domain has an IDE controller defined for a
machinetype that has no IDE controllers, libvirt will log an error
about the controller itself as it is building the qemu commandline
(rather than a (possible) error from qemu about disks attached to that
controller). This is done by adding IDE to the list of controller
types that are handled in the loop that creates controller command
strings in qemuBuildCommandline() (previously it would *always* skip
IDE controllers). Then qemuBuildControllerDevStr() is modified to log
an appropriate error in the case of IDE controllers.
In the future, if we add support for extra IDE controllers (piix3-ide
and/or piix4-ide) we can just add it into the IDE case in
qemuBuildControllerDevStr(). For now, nobody seems anxious to add
extra support for an aging and very slow controller, when there are so
many better options available.

Back in 2013, commit 877bc089 added in some tests that made sure no
error was generated on a domain definition that had an automatically
added usb controller if that domain didn't have a PCI bus to attach
the usb controller to. This was done because, at that time, libvirt
was automatically adding a usb controller to *any* domain definition
that didn't have one. Along with permitting the controller, two
s390-specific tests were added to ensure this behavior was maintained
- one with <controller type='usb' model='none'/> and another (called
"s390-piix-controllers") that had both usb and ide controllers, but
nothing attached to them.
Then in February of this year, commit 09ab9dcc eliminated the annoying
auto-adding of a usb device for s390 and s390x machines, stating:
"Since s390 does not support usb the default creation of a usb
controller for a domain should not occur."
Although, as verified here, the s390 doesn't support usb, and usb
controllers aren't currently added to s390 domain definitions
automatically, there are likely still some domain definitions in the
wild that have a usb controller (which was added *by libvirt*, not by
the user), so we will keep the tests verifying that behavior for
now. But this patch changes the names of the tests to reflect that
they don't actually contain a valid s390 config; this way future
developers won't propagate the incorrect idea that an s390 virtual
machine can have a USB (or IDE) bus.
In the case of the IDE controller, though, libvirt has never
automatically added an IDE controller unless a user added an IDE disk
(which itself would have caused an error), and we specifically *do*
want to begin generating an error when someone tries to add an IDE
controller to a domain that can't support one. For that reason, while
renaming the sz390-piix-controllers patch, this patch removes the
<controller type='ide'...> from it (otherwise the upcoming patch would
break make check)
This makes sure that that the commandlines generated for devices and
controller devices are all using the alias that has been set in the
controller's object as the id of the controller, rather than
hardcoding a printf (or worse, encoding exceptions to the standard
${controller}${index} into the logic)
Since this "fixes" the controller name used for the sata controller,
the commandline arg for the sata controller in the sata test case had
to be adjusted to be "sata0" instead of "ahci0". All other tests
remain unchanged, verifying that the patch causes no other functional
change.
Because the function that finds a controller alias based on a device
def requires a pointer to the full domainDef in order to get the list
of controllers, the arglist of a few functions had to have this added.
gcc5 reports an error like this:
bhyvexml2argvtest.c: In function 'testCompareXMLToArgvFiles':

cc1: all warnings being treated as errors
Fix by dropping this variable.
My commit 747761a79 (v1.2.15 only) dropped this bit of logic when filling
in a default arch in the XML:
- /* First try to find one matching host arch */
- for (i = 0; i < caps->nguests; i++) {
- if (caps->guests[i]->ostype == ostype) {
- for (j = 0; j < caps->guests[i]->arch.ndomains; j++) {
- if (caps->guests[i]->arch.domains[j]->type == domain &&
- caps->guests[i]->arch.id == caps->host.arch)
- return caps->guests[i]->arch.id;
- }
- }
- }
That attempt to match host.arch is important, otherwise we end up
defaulting to i686 on x86_64 host for KVM, which is not intended.
Duplicate it in the centralized CapsLookup function.
Additionally add some testcases that would have caught this.

My commit 7b9de914 added some aarch64 CPU test cases. I wanted to test
two different code paths but inadvertently added two of the same test
cases.
The second code path (using <cpu><model>host</model</cpu>) isn't easily
exercised via the qemu tests anyways, I'll need to look elsewhere.
Regardless, remove the redundant tests for now
The only version that's supported in QEMU is version 2, currently.
Fortunately, it is enabled by aarch64 automatically, so there's
nothing for us that needs to be put onto command line.
