Some of the tests that are not a part of qemuBuildCommandLine were not
executed in the test suite. We can now reuse qemuProcessStartValidate to
integrate these tests.
Most of the qemuargv2xml tests are parsing old style qemu command
lines (with -disk, -serial, etc), and it gets its input from
qemuxml2argv output.
But since we've raise the minimum supported qemu version to 0.12.0,
which supports -device, once that changes propagates through libvirt
the vast majority of qemuxml2argv output is _not_ going to be using
old style qemu options.
In preparation for this, switch qemuargv2xml to use its own copies
of input and output, so it's not tied to qemuxml2argv results.
This is just a straight copy of the current tests.
I've noticed couple of warning in dmesg while debugging
something:
[ 9683.973754] HTB: quantum of class 10001 is big. Consider r2q change.
[ 9683.976460] HTB: quantum of class 10002 is big. Consider r2q change.
I've read the HTB documentation and linux kernel code to find out
what's wrong. Basically we need to pass another argument
"quantum" to our tc cmd line because the default computed by HTB
does not always work in which case the warning message is printed
out.

So, systemd-machined has this philosophy that machine names are like
hostnames and hence should follow the same rules. But we always allowed
international characters in domain names. Thus we need to modify the
machine name we are passing to systemd.
In order to change some machine names that we will be passing to systemd,
we also need to call TerminateMachine at the end of a lifetime of a
domain. Even for domains that were started with older libvirt. That
can be achieved thanks to virSystemdGetMachineNameByPID(). And because
we can change machine names, we can get rid of the inconsistent and
pointless escaping of domain names when creating machine names.
So this patch modifies the naming in the following way. It creates the
name as <drivername>-<id>-<name> where invalid hostname characters are
stripped out of the name and if the resulting name is longer, it
truncates it to 64 characters. That way we can start domains we
couldn't start before. Well, at least on systemd.
To make it work all together, the machineName (which is needed only with
systemd) is saved in domain's private data. That way the generation is
moved to the driver and we don't need to pass various unnecessary
arguments to cgroup functions.
The only thing this complicates a bit is the scope generation when
validating a cgroup where we must check both old and new naming, so a
slight modification was needed there.

The name is confusing, and there are just two uses: one is a test case,
and the other will be removed as part of an upcoming refactoring of
the hostdev code.
The current code was a little bit odd. At first we've removed all
possible implicit input devices from domain definition to add them later
back if there was any graphics device defined while parsing XML
description. That's not all, while formating domain definition to XML
description we at first ignore any input devices with bus different to
USB and VIRTIO and few lines later we add implicit input devices to XML.
This seems to me as a lot of code for nothing. This patch may look
to be more complicated than original approach, but this is a preferred
way to modify/add driver specific stuff only in those drivers and not
deal with them in common parsing/formating functions.
The update is to add those implicit input devices into config XML to
follow the real HW configuration visible by guest OS.
There was also inconsistence between our behavior and QEMU's in the way,
that in QEMU there is no way how to disable those implicit input devices
for x86 architecture and they are available always, even without graphics
device. This applies also to XEN hypervisor. VZ driver already does its
part by putting correct implicit devices into live XML.

A future patch will refactor the storage of the pinning information in a
way where the ordering will be lost. Order them numerically to avoid
changing the tests later.
Make bhyveload respect boot order as specified by os.boot section of the
domain XML or by "boot order" for specific devices. As bhyve does not
support a real boot order specification right now, it's just about
choosing a single device to boot from.
... and consolidate the cmdline/extra/root parsing to facilitate doing
so.
The logic is the same as xl's parse_cmdline from the current xen.git master
branch (e6f0e099d2c17de47fd86e817b1998db903cab61).
On the formatting side switch to producing cmdline= instead of extra=.
Update a few tests and add serveral more.
- test-cmdline is added to test the exclusive use of cmdline.
- test-fullvirt-direct-kernel-boot.cfg is updated due to the switch
on the formatting side and now tests the exclusive use of cmdline=.
- Tests are added for both paravirt and fullvirt where the .cfg uses
extra= and (paravirt only) root=. These are format (xl->xml) only
since the inverse will generate cmdline= hence is not a round trip
(which was already true if using root=, which used to generate
extra= on the way back).
- Tests are added for both paravirt and fullvirt where the .cfg
declares cmdline= as well as bogus extra= and (paravirt only) root=
entries which should be ignored. Again these are format only tests
since the inverse won't include the bogus lines.
The last two bullets here required splitting the DO_TEST macro into
two halves, as is done in the xmconfigtest.c case.
In order to introduce a use of VIR_WARN for logging I had to add

Add a new storage pool source device attribute 'part_separator=[yes|no]'
in order to allow a 'disk' storage pool using a device mapper multipath
device to not add the "p" partition separator to the generated device
name when libvirt_parthelper is run.
This will allow libvirt to find device mapper multipath devices which were
configured in /etc/multipath.conf to use 'user_friendly_names' or custom
'alias' names for the LUN.
In the commit aea47e48c4 we have fixed a single pointer within
driver structure. Since all callers pass statically allocated
driver on stack other pointers within driver may contain random
values too. Before touching it lets overwrite it with zeroes and

Autodeflate can be enabled/disabled for memballon device
of model 'virtio'.
xml:
<devices>
<memballoon model='virtio' autodeflate='on'/>
</devices>
qemu:
qemu -device virtio-balloon-pci,...,deflate-on-oom=on
Autodeflate cannot be enabled/disabled for running domain.
Use virDomainDefAddUSBController() to add an EHCI1+UHCI1+UHCI2+UHCI3
controller set to newly defined Q35 domains that don't have any USB
controllers defined.
The real Q35 machine puts the first USB controller set (EHCI+(UHCIx4))
on bus 0 slot 0x1D, and the 2nd USB controller set on bus 0 slot 0x1A,
so let's attempt to make the virtual machine match that for
controllers with auto-assigned addresses when possible.
Three test cases were added to assure that the proper addresses are
assigned - one with a single set of unaddressed USB controllers, one
with 3 (to grab both preferred slots plus one more), and one with the
order of the controller definitions reordered, to assure that the
auto-assignment isn't mixed up by order.
If the q35 specific disable s3/s4 setting isn't supported, fallback to
specifying the PIIX setting, which is the previous behavior. It doesn't
have any effect, but qemu will just warn about it rather than error:
qemu-system-x86_64: Warning: global PIIX4_PM.disable_s3=1 not used
qemu-system-x86_64: Warning: global PIIX4_PM.disable_s4=1 not used
Since it doesn't error, I don't think we should either, since there
may be configs in the wild that already have q35 + disable_s3/4 (via
virt-manager)
The condition was checking for UHCI (and OHCI for ppc64) availability so
that it can specify the proper device instead of legacy usb. However,
for ppc64, we don't need to check both OHCI and UHCI, but only OHCI as
that is the legacy default. The condition is so big that it was just a
matter of time when someone will make a mistake there, so let's use more
lines so that it is visible what the condition checks for.
This fixes usage of -device instead of -usb for ppc64 that supports
pci-usb-ohci and does not support piix3-usb-uhci.

Future changes will make some of these tests dependent on specific
QEMUCaps flags, so wire up the basic handling. Flags will be added
in future patches.
For the standard active/inactive XML testing, if we leave the file loading
up to the generic XML2XML infrastructure, we get the benefit of
VIR_TEST_REGENERATE_OUTPUT, at the price of a few more disk reads. Seems
worth it.
Since test files are formatted predictably nowadays, we can make
VIR_TEST_REGENERATE_OUTPUT handle most cases for us with a simple
replacement. test-wrap-argv.pl is still canon, but this bit makes
it easier to confirm test output changes during active development.
