7e73137495 qemu: command: Enforce setting XDG variables for system QEMU
For session mode, only XDG_CACHE_HOME is set, because we want to remain
integrating with services in user session, but for system mode, this
would have become reading/writing to '/' which carries the obvious issue
with permissions (also, '/' is the wrong location in 99.9% cases anyway).

68ade25372 qemu: Enable firmware autoselection
https://bugzilla.redhat.com/show_bug.cgi?id=1564270

Now that everything is prepared for qemu driver we can enable
parser feature to allow users define such domains.

At the same time, introduce bunch of tests to test the feature.

186bb479d0 qemu: Allow creating ppc64 guests with graphics and no USB mouse
The existing behavior for ppc64 guests is to always add a USB
keyboard and mouse combo if graphics are present; unfortunately,
this means any attempt to use a USB tablet will cause both pointing
devices to show up in the guest, which in turn will result in poor
user experience.

We can't just stop adding the USB mouse or start adding a USB tablet
instead, because existing applications and users might rely on the
current behavior; however, we can avoid adding the USB mouse if a USB
tablet is already present, thus allowing users and applications to
create guests that contain a single pointing device.

4d7ea75e1e tests: Add simple guests with graphics to qemuxml2argv
These are similar to the existing simple headless guests, but
also include a graphical output and some input devices.

Input files were generated by running

  $ virt-install \
    --name guest --os-variant fedora29 \
    --vcpus 4 --memory 4096 --disk size=5 \
    --graphics vnc \

448a094717 qemu: Support scsi controller model=virtio-{non-}transitional
Add <controller type='scsi' model handling for virtio transitional
devices. Ex:

  <controller type='scsi' model='virtio-transitional'/>

* "virtio-transitional" maps to qemu "virtio-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-scsi-non-transitional"

The naming here doesn't match the pre-existing model=virtio-scsi.
The prescence of '-scsi' there seems kind of redundant as we have
type='scsi' already, so I decided to follow the pattern of other
patches and use virtio-transitional etc.

qemu vhost-scsi devices map to XML roughly like:

    <hostdev mode='subsystem' type='scsi_host'>

To support vhost-scsi-pci-{non-}traditional in qemu, we
need to to extend the SCSI Host hostdev XML to handle
model= value. This matches the XML model= format used
for mediated devices. This is just the domain_conf bits
and some XML test cases.

Use of virtio-X naming here does not match the hostdev
protocol=vhost nor does it match the qemu vhost-X device
naming, however it's more consistent with all other
model= names in this area, and also matches the
inconsistency of <vsock> devices which use model=virtio
but map to vhost-vsock on the qemu commandline

25d05051b3 conf: Add <disk model='virtio-{non-}transitional'/>
<disk> devices lack the model= attribute which is used by
most other device types. bus= mostly acts as one, but it
serves other purposes too like determing what target=
prefix to use, and for matching against controller type=

Extending bus= to handle additional virtio transitional
devices will complicate apps lives, and it isn't a clean
mapping anyways. So let's bite the bullet and add a new
<disk model=X/> attribute, and wire up common handling
for virtio and virtio-{non-}transitional

6db0d03383 qemu: command: Don't skip 'readonly' and throttling info for empty drive
In commit f80eae8c2a I was too agresive in removing properties of
-drive for empty drives. It turns out that qemu actually persists the
state of 'readonly' and the throttling information even for the empty
drive.

Removing 'readonly' thus made qemu open any subsequent images added via
the 'change' command as RW which was forbidden by selinux thanks to the
restrictive sVirt label for readonly media.

Fix this by formating the property again and bump the tests and leave a
note detailing why the rest of the properties needs to be skipped.

f80eae8c2a qemu: command: Don't format image properties for empty -drive
If a -drive has no image, using image properties makes qemu whine that
they should not be used.

This patch stops formating cache/readonly/... for empty drives
for the pre-blockdev syntax. Unfortunately those parameters can't be
added later when inserting media, but on the other hand qemu will start
with an empty drive.

Since we already were able to start a VM with such config previously due
to qemu ignoring them I've opted just to skip formatting them.
Additionally with -blockdev support it will work as expected as the
image properties will be formatted when adding the image itself which is
not possible without it.

c658764dec qemu: Don't use -mem-prealloc among with .prealloc=yes
https://bugzilla.redhat.com/show_bug.cgi?id=1624223

There are two ways to request memory preallocation on cmd line:
-mem-prealloc and .prealloc attribute for a memory-backend-file.
However, as it turns out it's not safe to use both at the same
time. If -mem-prealloc is used then qemu will fully allocate the
memory (this is done by actually touching every page that has
been allocated). Then, if .prealloc=yes is specified,
mbind(flags = MPOL_MF_STRICT | MPOL_MF_MOVE) is called which:

a) has to (possibly) move the memory to a different NUMA node,
b) can have no effect when hugepages are in play (thus ignoring user
request to place memory on desired NUMA nodes).

Prefer -mem-prealloc as it is more backward compatible
compared to switching to "-numa node,memdev=  + -object
memory-backend-file".

24b74d187c qemu: add memfd source type
Add a new memoryBacking source type "memfd", supported by QEMU (when
the capability is available).

A memfd is a specialized anonymous memory kind. As such, an anonymous
source type could be automatically using a memfd. However, there are
some complications when migrating from different memory backends in
qemu (mainly due to the internal object naming at this point, but
there could be more). For now, it is simpler and safer to simply
introduce a new source type "memfd". Eventually, the "anonymous" type
could learn to use memfd transparently in a separate change.

The main benefits are that it doesn't need to create filesystem files,
and it also enforces sealing, providing a bit more safety.

7ea7342996 conf: correct false boot order error during domain parse
virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.

Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.

To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.

614193fac6 conf: Fix check for chardev source path
Attempting to use a chardev definition like

  <serial type='unix'>
    <target type='isa-serial'/>

correctly results in an error being reported, since the source
path - a required piece of information - is missing; however,
the very similar

  <serial type='unix'>
    <target type='pci-serial'/>
  </serial>

was happily accepted by libvirt, only to result in libvirtd
crashing as soon as the guest was started.

The issue was caused by checking the chardev's targetType
against whitelisted values from virDomainChrChannelTargetType
without first checking the chardev's deviceType to make sure
it is actually a channel, for which the check makes sense,
rather than a different type of chardev.

The only reason this wasn't spotted earlier is that the
whitelisted values just so happen to correspond to USB and
PCI serial devices and Xen and UML consoles respectively,
all of which are fairly uncommon.

fe67e3e28e qemu: Validate memory access during validate domain config
Commit 6534b3c4 tried to raise an error when there is no numa
nodes by setting access='shared' in the domain config, but added
a helper called from qemuDomainDeviceDefValidate instead of a
helper called from qemuDomainDefValidate for XML:

  <memoryBacking>
    <hugepages/>
    <access mode='shared'/>
  </memoryBacking>

Since there are no memory devices in the test XML, there would
be no validation failure, but the test added was still failing.
Investigating that it turns out that unnecessary XML elements
were causing the failure (no need for <video>, <graphics>,
<pm>, usb controller model "piix3-uhci", disk attribute for
"discard='unmap'", <serial>, <console>, <channel> and a
memballoon model). Removing all those before moving the method
caused the test to succeed.

So this patch moves the validation to the right place and
removes all the unnecessary XML pieces that were causing
a false validation failure.

0fa11dc0c9 tests: qemuxml2argv: Drop some unused args files
aarch64-acpi-nouefi and hostdev-scsi-boot are unused. Noticed when
checking whether '-nodefconfig' is still used by libvirt.

Unused since their introduction in commit deb38c4 and bab6ee6
respectively.

9a28d3fd92 conf: Allow formatting and parsing of 'index' for disk source image
Similarly to backing store indexes which will become stable eventually
we need also to be able to format and store in the status XML for later
use the index for the top level of the backing chain.

Add XML formatter, parser, schema and docs.
