ca437d0603 qemu: Refuse partitions in disk targets
The way in which the qemu driver generates aliases for disks involves
ignoring the partition number part of a target dev name.  This means that
all partitions of a block device and the device itself all end up with the
same alias.  If multiple such disks are specified in XML, the resulting
name clash makes qemu invocation fail.

Since attaching partitions to qemu VMs doesn't seem to make much sense
anyway, disallow partitions in target specifications altogether.

      qemu: add qemuDomainVideoPrivate

Since the test suite does not invoke qemuExtDevicesStart(), no
vhost_user_fd will be present when generating test XML. To deal
with this we can must a fake FD number. While the current XML
is using FD == 0, we pick a very interesting number that's unlikely
to be a real FD, so that we're more likely to see any mistakes
closing the invalid FD.

7cd0911e1a qemu: support unmanaged target tap dev for <interface type='ethernet'>
If managed='no', then the tap device must already exist, and setting
of MAC address and online status (IFF_UP) is skipped.

NB: we still set IFF_VNET_HDR and IFF_MULTI_QUEUE as appropriate,
because those bits must be properly set in the TUNSETIFF we use to set
the tap device name of the handle we've opened - if IFF_VNET_HDR has
not been set and we set it the request will be honored even when
running libvirtd unprivileged; if IFF_MULTI_QUEUE is requested to be
different than how it was created, that will result in an error from
the kernel. This means that you don't need to pay attention to
IFF_VNET_HDR when creating the tap devices, but you *do* need to set
IFF_MULTI_QUEUE if you're going to use multiple queues for your tap
device.

NB2: /dev/vhost-net normally has permissions 600, so it can't be
opened by an unprivileged process. This would normally cause a warning
message when using a virtio net device from an unprivileged
libvirtd. I've found that setting the permissions for /dev/vhost-net
permits unprivileged libvirtd to use vhost-net for virtio devices, but
have no idea what sort of security implications that has. I haven't
changed libvrit's code to avoid *attempting* to open /dev/vhost-net -
if you are concerned about the security of opening up permissions of
/dev/vhost-net (probably a good idea at least until we ask someone who
knows about the code) then add <driver name='qemu'/> to the interface
definition and you'll avoid the warning message.

Note that virNetDevTapCreate() is the correct function to call in the
case of an existing device, because the same ioctl() that creates a
new tap device will also open an existing tap device.

77f72a8615 conf: new "managed" attribute for target dev of <interface type='ethernet'>
Although <interface type='ethernet'> has always been able to use an
existing tap device, this is just a coincidence due to the fact that
the same ioctl is used to create a new tap device or get a handle to
an existing device.

Even then, once we have the handle to the device, we still insist on
doing extra setup to it (setting the MAC address and IFF_UP).  That
*might* be okay if libvirtd is running as a privileged process, but if
libvirtd is running as an unprivileged user, those attempted
modifications to the tap device will fail (yes, even if the tap is set
to be owned by the user running libvirtd). We could avoid this if we
knew that the device already existed, but as stated above, an existing
device and new device are both accessed in the same manner, and
anyway, we need to preserve existing behavior for those who are
already using pre-existing devices with privileged libvirtd (and
allowing/expecting libvirt to configure the pre-existing device).

In order to cleanly support the idea of using a pre-existing and
pre-configured tap device, this patch introduces a new optional
attribute "managed" for the interface <target> element. This
attribute is only valid for <interface type='ethernet'> (since all
other interface types have mandatory config that doesn't apply in the
case where we expect the tap device to be setup before we
get it). The syntax would look something like this:

   <interface type='ethernet'>
      <target dev='mytap0' managed='no'/>
      ...
   </interface>

This patch just adds managed to the grammar and parser for <target>,
but has no functionality behind it.

(NB: when managed='no' (the default when not specified is 'yes'), the
target dev is always a name explicitly provided, so we don't
auto-remove it from the config just because it starts with "vnet"
(VIR_NET_GENERATED_TAP_PREFIX); this makes it possible to use the
same pattern of names that libvirt itself uses when it automatically
creates the tap devices.)

9f90a4bfb4 qemu: maintain user alias for video type 'none'
After parsing a video device with a model type of
VIR_DOMAIN_VIDEO_TYPE_NONE, all device info is cleared (see
virDomainDefPostParseVideo()) in order to avoid formatting any
auto-generated values for the XML. Subsequently, however, an alias is
generated for the video device (e.g. 'video0'), which results in an
alias property being formatted in the XML output anyway. This creates
confusion if the user has explicitly provided an alias for the video
device since the alias will change.

To avoid this, don't clear the user-defined alias for video devices of
type "none".

d19c21429f virpci: Allow greater PCI domain value in virPCIDeviceAddressIsValid
There is no restriction on maximum value of PCI domain. In fact,
Linux kernel uses plain atomic inc when assigning PCI domains:

drivers/pci/pci.c:static int pci_get_new_domain_nr(void)
drivers/pci/pci.c-{
drivers/pci/pci.c-      return atomic_inc_return(&__domain_nr);
drivers/pci/pci.c-}

Of course, this function is called only if kernel was compiled
without PCI domain support or ACPI did not provide PCI domain.

However, QEMU still has the same restriction as us: in
set_pci_host_devaddr() QEMU checks if domain isn't greater than
0xffff. But one can argue that that's a QEMU limitation. We still
want to be able to cope with other hypervisors that don't have
this limitation (possibly).

2c4c347c4b qemu: block: Use 'auto-read-only' instead of 'read-only' for backing chain
To allow using -blockdev with blockjobs QEMU needs to reopen files in
read-write mode when modifying the backing chain. To achieve this we
need to use 'auto-read-only' for the backing files rather than the
normal 'read-only' property. That way qemu knows that the files need to
be reopened.

Note that the format drivers (e.g. qcow2) are still opened with the
read-only property enabled when being a member of the backing chain
since they are supposed to be immutable unless a block job is started.

QEMU v4.0 (since commit 23dece19da4) allows also dynamic behaviour for
auto-read-only which allows us to use sVirt as we only grant write
permissions to files when doing a blockjob.

7711a7346a qemu: Relax os.loader->type check when validating domain
When validating a domain among all the checks there are two that
concern VIR_DOMAIN_LOADER_TYPE_PFLASH specifically. The first
check ensures that on x86 ACPI is enabled when UEFI is requested,
the second ensures that UEFI is used when ACPI is requested on
aarch64. However, check for UEFI is done by plain comparison of
def->os.loader->type which is insufficient because we have
def->os.firmware too.

NB, this wouldn't be a problem for active domain, because on
startup process def->os.loader->type gets filled by
qemuFirmwareEnableFeatures(), but that's not the case for
inactive domains.

The command line is once again along the lines of

  $ virt-install \
    --name guest --os-variant fedora29 \
    --vcpus 4 --memory 4096 --disk size=5 \
    --graphics (none|vnc) \
    --print-xml

with some minor tweaks performed afterwards.

This removes a number of inconsistencies between the files,
and makes it so the only differences are actually relevant
either to the architecture and machine type at hand, or to
having graphics rather than being headless.

e13e64f49a tests: Normalize quotes for *-graphics
Right now *-headless and *-graphics tests are using different
quoting styles, which results in the diff between them being
basically useless, whereas we would like it to be possible to
compare these files directly and easily spot the differences.

Convert all *-graphics tests to single quotes, which is the
style libvirt itself uses when formatting XML: this is a fact
that will come in handy later.

Use the DO_TEST_CAPS_LATEST/VER infrastructure to run a more modern
version of this and also fork it to a pre-blockdev version so that we
can check the qemu namespace capability tweaking.

c6da5913d9 qemu: Add support for controling qemu capabilities via the qemu XML namespace
Similarly how we allow adding arbitrary command line arguments and
environment variables this patch introduces the ability to control
libvirt's perception of the qemu process by tweaking the capability bits
for testing purposes.

The idea is to allow developers and users either test a new feature by
enabling it early or disabling it to see whether it introduced
regressions.

This feature is not meant for production use though, so users should
handle it with care.

5030a7450b qemu_command: Use canonical names of CPU features
When building QEMU command line, we should use the preferred spelling of
each CPU feature without relying on compatibility aliases (which may be
removed at some point).

The "unavailable-features" CPU property is used as a witness for the
correct names of the features in our translation table.
