1a324c2f88 qemu: newer -numa parameter capability probing
When qemu switched to using OptsVisitor for -numa parameter, it did
two things in the same patch.  One of them is that the numa parameter
is now visible in "query-command-line-options", the second one is that
it enabled using disjoint cpu ranges for -numa specification.  This
will be used in later patch.

f3be5f0c50 Add support for timestamping QEMU logs
QEMU commit 5e2ac51 added a boolean '-msg timestamp=[on|off]'
option, which can enable timestamps on errors:
$ qemu-system-x86_64 -msg timestamp=on zghhdorf
2014-04-09T13:25:46.779484Z qemu-system-x86_64: -msg timestamp=on: could
not open disk image zghhdorf: Could not open 'zghhdorf': No such file or
directory

Enable this timestamp if the QEMU binary supports it.

Add a 'log_timestamp' option to qemu.conf for disabling this behavior.

17133e3702 qemu: add host-pci-multidomain capability
Quite a long time ago, (apparently between qemu 0.12 and 0.13) qemu
quietly began supporting the optional specification of a domain in the
host-side address of all pci passthrough commands (by simply
prepending it to the bus:slot.function format, as
"dddd:bb:ss.f"). Since machines with multiple PCI domains are very
rare, this never came up in practice, so libvirt was never updated to
support it.

This patch takes the first step to supporting specification of a non-0
domain in the host-side address of PCI devices being assigned to a
domain, by adding a capability bit to indicate support
"QEMU_CAPS_HOST_PCI_MULTIDOMAIN", and detect it. Since this support
was added in a version prior to the minimum version required for
QMP-style capabilities detection, the capability is always enabled for
any qemu that uses QMP for capabilities detection. For older qemus,
the only clue that a domain can be specified in the host pci address
is the presence of the string "[seg:]" in the help string for
-pcidevice. (Ironically, libvirt will not be modified to support
specification of domain for -pcidevice, since any qemu new enough for
us to care about also supports "-device pci-assign" or "-device
vfio-pci", which are greatly preferred).

d27e6bc40f qemu: introduce spiceport chardev backend
Add a new backend for any character device.  This backend uses channel
in spice connection.  This channel is similar to spicevmc, but
all-purpose in contrast to spicevmc.

Apart from spicevmc, spiceport-backed chardev will not be formatted
into the command-line if there is no spice to use (with test for that
as well).  For this I moved the def->graphics counting to the start
of the function so its results can be used in rest of the code even in
the future.

19bbc81276 spice: detect if qemu can disable file transfer
spice-server offers an API to disable file transfer messages
on the agent channel between the client and the guest.
This is supported in qemu through the disable-agent-file-xfer option.

This patch detects if QEMU supports this option, and add
a capability if does.

15275f2edb qemu: check for reboot-timeout on monitor
The support for <boot rebootTimeout="12345"/> was added before we were
checking for qemu command line options in QMP, so we haven't properly
adapted virQEMUCaps when using it and thus we report unsupported
option with new enough qemu.

line of qemu.  Clients can then couple the <panic> device and the

96fddee322 qemu: add "-boot strict" to commandline whenever possible
This resolves:

  https://bugzilla.redhat.com/show_bug.cgi?id=888635

(which was already closed as CANTFIX because the qemu "-boot strict"
commandline option wasn't available at the time).

Problem: you couldn't have a domain that used PXE to boot, but also
had an un-bootable disk device *even if that disk wasn't listed in the
boot order*, because if PXE timed out (e.g. due to the bridge
forwarding delay), the BIOS would move on to the next target, which
would be the unbootable disk device (again - even though it wasn't
given a boot order), and get stuck at a "BOOT DISK FAILURE, PRESS ANY
KEY" message until a user intervened.

The solution available since sometime around QEMU 1.5, is to add
"-boot strict=on" to *every* qemu command. When this is done, if any
devices have a boot order specified, then QEMU will *only* attempt to
boot from those devices that have an explicit boot order, ignoring the
rest.

Since qemu-kvm 1.1 [1] (since 1.3. in upstream QEMU [2])
'-no-kvm-pit-reinjection' has been deprecated.
Use -global kvm-pit.lost_tick_policy=discard instead.
