c1c4d0d5a5 tests: qemuxml2xml: assign device addresses
We use the PreFormat callback for this. Many test cases need to be extended
to pass in proper qemuCaps flags so AssignAddresses doesn't throw errors.

One test case (pcie-root-port-too-many) is dropped, since it was meant
only for checking an error condition in qemuxml2argv, and one we add in
AssignAddresses it errors here too.

Long term I think AssignAddresses should be handled in qemu's PostParse
callback, but that's not entirely straightforward. Handling it here
means we can get the test suite churn over with.

e9394d699c tests: qemuxml2argv: remove some QEMU_CAPS_DEVICE problem cases
When we unconditionally enable QEMU_CAPS_DEVICE, these tests need
some massaging, so do it ahead of time to not mix it in with the
big test refresh.

- minimal-s390 is not a real world working config, so drop it
- disk-usb was testing for an old code path that will be removed.
  instead use it to test lack of USB disk support, and rename it
  to disk-usb-nosupport. Switch xml2xml to use disk-usb-device for
  input.
- cputune-numatune was needlessly using q35, switch it to an older
  machine type

d093d623e3 tests: qemuxml2xml: Always use different output file
Most qemuxml2xml tests expect that the input XML is unchanged after
parsing. This is unlike 99% of new qemu configs in the wild, which after
initial parsing end up with stable PCI device addresses. The xml2xml bit
doesn't currently hit that code path though, so most XML testing indeed
does not change.

Future patches will add that PCI address bits, which means most test cases
will have different output. So let's do away with the hardcoded same vs
different test split, and always track a separate output file. Tests can
still have same input and output, it just necessitates 2 separate XML files.

e117bf642b tests: qemuargv2xml: separate from qemuxml2argv data
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.

065054daa7 virnetdevbandwidth: Compute quantum value
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.

c3bd0019c0 systemd: Modernize machine naming
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.

36785c7e77 device: cleanup input device 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.

daeace5c5d libxl: Support cmdline= in xl config files
... 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
virerror.h and VIR_LOG_INIT.

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.

7140807917 qemu: Don't bother user with libvirt-internal paths
If user defines a virtio channel with UNIX socket backend and doesn't
care about the path for the socket (e.g. qemu-agent channel), we still
generate it into the persistent XML.  Moreover when then user renames
the domain, due to its persistent socket path saved into the per-domain
directory, it will not start.  So let's forget about old generated paths
and also stop putting them into the persistent definition.

d7db33bfe9 qemu: Specify format= iff disk source is not empty
Just recently, qemu forbade specifying format for sourceless
disks (qemu commit 39c4ae941ed992a3bb5). It kind of makes sense.
If there's no file to open, why specify its format. Anyway, I
have a domain like this:

    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <target dev='hda' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

and obviously I am unable to start it. Therefore, a fix on our
side is needed too.

6d9cdd2a57 pci: Introduce virPCIStubDriver enumeration
This replaces the virPCIKnownStubs string array that was used
internally for stub driver validation.

Advantages:

  * possible values are well-defined
  * typos in driver names will be detected at compile time
  * avoids having several copies of the same string around
  * no error checking required when setting / getting value

The names used mirror those in the
virDomainHostdevSubsysPCIBackendType enumeration.

5b74103b0b Xen: support maxvcpus in xm and xl config
From: Ian Campbell <ian.campbell@citrix.com>

xend prior to 4.0 understands vcpus as maxvcpus and vcpu_avail
as a bit map of which cpus are online (default is all).

xend from 4.0 onwards understands maxvcpus as maxvcpus and
vcpus as the number which are online (from 0..N-1). The
upstream commit (68a94cf528e6 "xm: Add maxvcpus support")
claims that if maxvcpus is omitted then the old behaviour
(i.e. obeying vcpu_avail) is retained, but AFAICT it was not,
in this case vcpu==maxcpus==online cpus. This is good for us
because handling anything else would be fiddly.

This patch changes parsing of the virDomainDef maxvcpus and vcpus
entries to use the corresponding 'maxvcpus' and 'vcpus' settings
from xm and xl config. It also drops use of the old Xen 3.x
'vcpu_avail' setting.

The change also removes the maxvcpus limit of MAX_VIRT_VCPUS (since
maxvcpus is simply a count, not a bit mask), which is particularly
crucial on ARM where MAX_VIRT_CPUS == 1 (since all guests are
expected to support vcpu placement, and therefore only the boot
vcpu's info lives in the shared info page).

Existing tests adjusted accordingly, and new tests added for the
'maxvcpus' setting.
