'virsh attach-disk' uses stat() to determine if the 'source' is a
regular file. If stat fails though it assumes that the file is block.
Since it's way more common to have regular files and the detection does
not work at all when accessing a remote host, modify the default to
assume type='file' by default.

The ESP SCSI controllers (NCR53C90, DC390, AM53C974) have the same
requirement as the LSI Logic controller for each disk to be set via
the scsi-id=NNN property, not the lun=NNN property.
Switching the code to use an enum will force authors to pay attention
to this difference when adding future SCSI controllers.

The NCR53C90 is the built-in SCSI controller on all sparc machine types,
but not sparc64. Note that it has the fixed alias "scsi", which differs
from our normal naming convention of "scsi0".
The DC390 and AM53C974 are PCI SCSI controllers that can be added to any
PCI machine.
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
Probing for the NCR53C90 controller is a little unusual. The
qom-list-types QMP command returns a list of all types known to
the QEMU binary. It does not distinguish devices which are user
creatable from those which are built-in.
Any QEMU target that supports PCI will have the DC390 / AM53C974
devices because they are PCI based. Due to code dependencies
in QEMU though, existence of these two devices will also pull in
the NCR53C90 device (called just 'esp' in QEMU). The NCR53C90 is
not user-creatable and can only be used when built-in to the
machine type.
This is only the case on sparc machines, and certain mips64 and
m68k machines. IOW, we don't rely on qom-list-types as a guide
for existence of NCR53C90, as it shouldn't really exist in most
QEMU binaries.

The sparc machines have little in common with sparc64 machines.
No sparc machine type includes a PCI bus, so we should not be adding one
to the XML. This further means that we should not be adding a memory
balloon device, nor USB controller as these are both PCI based.

We're no longer generating a UUID during installation, so we
clearly don't need to strip it afterwards; and since the network
driver is perfectly capable of generating a UUID if necessary, we
don't need to do that at %post time either.

We are generating a fresh UUID and storing it in the XML for the
default network, but this is unnecessary because the network
driver will automatically generate one if it's missing from the
XML; the fact that we only do this if the uuidgen command happens
to be available on the build machine is further proof that we can
safely skip this step.
This patch is best viewed with 'git show -w'.

While we generally expect libvirt objects to be defined using the
appropriate APIs, there are cases where it's reasonable for an
external entity, usually a package manager, to drop a valid
configuration file under /etc/libvirt and have libvirt take over
from there: notably, this is exactly how the default network is
handled.
For the most part, whether the configuration is saved back to disk
after being parsed by libvirt doesn't matter, because we'll end up
with the same values anyway, but an obvious exception to this is
data that gets randomly generated when not present, namely MAC
address and UUID.
Historically, both were handled by our build system, but commit
a47ae7c004 moved handling of the former inside libvirt proper;
this commit extends such behavior to the latter as well.
Proper error handling for the virNetworkSaveConfig() call, which
was missing until now, is introduced in the process.

The way our domain capabilities work currently, is that we have
virDomainCapsEnum struct which contains 'unsigned int values'
member which serves as a bitmask. More complicated structs are
composed from this struct, giving us whole virDomainCaps
eventually.
Whenever we want to report that a certain value is supported, the
'1 << value' bit is set in the corresponding unsigned int member.
This works as long as the resulting value after bitshift does not
overflow unsigned int. There is a check inside
virDomainCapsEnumSet() which ensures exactly this, but no caller
really checks whether virDomainCapsEnumSet() succeeded. Also,
checking at runtime is a bit too late.
Fortunately, we know the largest value we want to store in each
member, because each enum of ours ends with _LAST member.
Therefore, we can check at build time whether an overflow can
occur.

Using virtCgroupNewSelf() is not correct with cgroups v2 because the
the virt-host-validate process is executed from from the same cgroup
context as the terminal and usually not all controllers are enabled
by default.
To do a proper check we need to use the root cgroup to see what
controllers are actually available. Libvirt or systemd ensures that
all controllers are available for VMs as well.
This still doesn't solve the devices controller with cgroups v2 where
there is no controller as it was replaced by eBPF. Currently libvirt
tries to query eBPF programs which usually works only for root as
regular users will get permission denied for that operation.
