Allow an arbitrary timezone with QEMU by setting the $TZ environment
variable when launching QEMU
* src/qemu/qemu_conf.c: Set TZ environment variable if a timezone
is requested
* tests/qemuxml2argvtest.c: Add test case for timezones
* tests/qemuxml2argvdata/qemuxml2argv-clock-france.xml,
tests/qemuxml2argvdata/qemuxml2argv-clock-france.args: Data
for timezone tests
This allows QEMU guests to be started with an arbitrary clock
offset
The test case can't actually be enabled, since QEMU argv expects
an absolute timestring, and this will obviously change every
time the test runs :-( Hopefully QEMU will allow a relative
time offset in the future.
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Use the -rtc arg
if available to support variable clock offset mode
* tests/qemuhelptest.c: Add QEMUD_CMD_FLAG_RTC for qemu 0.12.1
* qemuxml2argvdata/qemuxml2argv-clock-variable.args,
qemuxml2argvdata/qemuxml2argv-clock-variable.xml,
qemuxml2argvtest.c: Test case, except we can't actually enable
it yet.
Support virtio-serial controller and virtio channel in QEMU backend.
Will output
the following for virtio-serial controller:
-device
virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x4,max_ports=16,vectors=4
and the following for a virtio channel:
-chardev pty,id=channel0 \
-device
virtserialport,bus=virtio-serial0.0,chardev=channel0,name=org.linux-kvm.port.0
* src/qemu/qemu_conf.c: Add argument output for virtio
* tests/qemuxml2argvtest.c
tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args: Add test for
QEMU command line generation
Use the ATTRIBUTE_NONNULL annotation to mark some virConnectPtr
args as mandatory non-null so the compiler can warn of mistakes
* src/conf/domain_event.h: All virConnectPtr args must be non-null
* src/qemu/qemu_conf.h: qemudBuildCommandLine and
qemudNetworkIfaceConnect() must be given non-null connection
* tests/qemuxml2argvtest.c: Provide a non-null (dummy) connection to
qemudBuildCommandLine()
The QEMU flags are commonly stored as a signed or unsigned int,
allowing only 31 flags. This limit is rather close, so to aid
future patches, change it to a 64-bit int
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c,
tests/qemuargv2xmltest.c, tests/qemuhelptest.c, tests/qemuxml2argvtest.c:
Use 'unsigned long long' for QEMU flags
The QEMU 0.12.x tree has the -netdev command line argument, but not
corresponding monitor command. We can't enable the former, without
the latter since it will break hotplug/unplug.
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Disable -netdev usage
until 0.13 at earliest
* tests/qemuxml2argvtest.c: Add test for -netdev syntax
* tests/qemuxml2argvdata/qemuxml2argv-net-virtio-netdev.args,
tests/qemuxml2argvdata/qemuxml2argv-net-virtio-netdev.xml: Test
data files for -netdev syntax
The current QEMU code allocates PCI addresses incrementally starting
at 4. This is not satisfactory because the user may have given some
addresses in their XML config, which need to be skipped over when
allocating addresses to remaining devices.
It is thus neccessary to maintain a list of already allocated PCI
addresses and then only allocate ones that remain unused. This is
also required for domain device hotplug to work properly later.
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
list of existing PCI addresses, and allocating new addresses.
Refactor address assignment to use this code
* src/qemu/qemu_driver.c: Pull PCI address assignment up into the
qemuStartVMDaemon() method, as a prelude to moving it into the
'define' method. Update list of allocated addresses when connecting
to a running VM at daemon startup.
* tests/qemuxml2argvtest.c, tests/qemuargv2xmltest.c,
tests/qemuxml2xmltest.c: Remove USB product test since all
passthrough is done based on address
* tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.args,
tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.xml: Kil
unused data files
The test expected all environment variables copied in qemudBuildCommandLine
to have known values. So all of them have to be either set to a known value
or be unset. SDL_VIDEODRIVER and QEMU_AUDIO_DRV are not handled at all but
should be handled. Unset both, otherwise the test will fail if they are set
in the testing environment.
* src/qemu/qemu_conf.c: add a comment about copied environment variables
and qemuxml2argvtest
* tests/qemuxml2argvtest.c: unset SDL_VIDEODRIVER and QEMU_AUDIO_DRV
QEMU always configures a VGA card. If no video card is included in
the libvirt XML, it is neccessary to explicitly turn off the default
using -vga none
* src/qemu/qemu_conf.c: Pass -vga none if no video card is configured
* tests/qemuargv2xmltest.c, tests/qemuxml2argvtest.c: Test for
handling -vga none.
* tests/qemuxml2argvdata/qemuxml2argv-nographics-vga.args,
tests/qemuxml2argvdata/qemuxml2argv-nographics-vga.xml: Test
data files
The old syntax was
-usbdevice host:PRODUCT:VENDOR
Or
-usbdevice host:BUS.DEV
The new syntax is
-device usb-host,product=PRODUCT,vendor=VENDOR
Or
-device usb-host,hostbus=BUS,hostaddr=DEV
The previous syntax was severely limited in its options
-usbdevice disk:/home/berrange/output.img
The new syntax is the same as for other disk types
-drive file=/home/berrange/output.img,if=none,id=usb-1,index=1
-device usb-storage,drive=usb-1
Again, the index= arg is wrong here, and will be removed in a
later merge
The current syntax uses a pair of args
-net nic,macaddr=52:54:00:56:6c:55,vlan=3,model=pcnet,name=pcnet.0
-net user,vlan=3,name=user.0
The new syntax does not need the vlan craziness anymore, and
so has a simplified pair of args
-netdev user,id=user.0
-device pcnet,netdev=user.0,id=pcnet.0,mac=52:54:00:56:6c:55,addr=<PCI SLOT>
The current syntax for audio devices is a horrible multiplexed
arg
-soundhw sb16,pcspk,ac97
The new syntax is
-device sb16,id=sound0
or
-device AC97,id=sound1,addr=<PCI SLOT>
NB, pcspk still uses the old -soundhw syntax
The current character device syntax uses either
-serial tty,path=/dev/ttyS2
Or
-chardev tty,id=serial0,path=/dev/ttyS2 -serial chardev:serial0
With the new -device support, we now prefer
-chardev file,id=serial0,path=/tmp/serial.log -device isa-serial,chardev=serial0
This patch changes the existing -chardev syntax to use this new
scheme, and fallbacks to the old plain -serial syntax for old
QEMU.
The monitor device changes to
-chardev socket,id=monitor,path=/tmp/test-monitor,server,nowait -mon chardev=monitor
In addition, this patch adds --nodefaults, which kills off the
default serial, parallel, vga and nic devices. THis avoids the
need for us to explicitly turn each off
Change -monitor, -serial and -parallel output to use -chardev if it is
available.
* src/qemu/qemu_conf.c: Update qemudBuildCommandLine to use -chardev where
available.
* tests/qemuxml2argvtest.c tests/qemuxml2argvdata/: Add -chardev equivalents
for all current serial and parallel tests.

* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
impl of QMP protocol
* src/Makefile.am: Add src/qemu/qemu_monitor_json.{c,h}
Introduce a new type="dir" mode for <disks> that allows use of
QEMU's virtual FAT block device driver. eg
<disk type='dir' device='floppy'>
<source dir='/tmp/test'/>
<target dev='fda' bus='fdc'/>
<readonly/>
</disk>
gets turned into
-drive file=fat:floppy:/tmp/test,if=floppy,index=0
Only read-only disks are supported with virtual FAT mode

-net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0
* src/qemu/qemu_conf.c: Add argument output for channel
* tests/qemuxml2(argv|xml)test.c: Add test for <channel> domain syntax
Latest upstream QEMU can be built with Xen support, which introduces
a -xen-domid argument. This was mistakenly detected as -domid due
to old Xenner support. Adapt to cope with both syntax. Also only
set domid if the virt type is xen, or the guest type is xen
* src/qemu_conf.c, src/qemu_conf.h: Detect new -xen-domid flag in
preference to -domid.
* tests/qemuxml2argvdata/qemuxml2argv-bootloader.args,
tests/qemuxml2argvdata/qemuxml2argv-input-xen.args: Add missing

tests/qemuxml2argvtest.c: add a test using /usr/bin/kvm and make
sure that 'pc' machine type doesn't get canonicalized using the
aliases in the guest machine type list
* tests/testutilsqemu.c: make 'pc' an alias for qemu-system-x86_64
* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases1.*,
tests/qemuxml2argvtest.c: add a test which uses qemu-system-x86_64
and make sure the machine type is canonicalized.
This doesn't have any affect on the current tests because we don't have
any machine aliases in the current test data.
* src/qemu_conf.h, src/qemu_driver.c: expose qemudCanonicalizeMachine()
for the tests
* tests/qemuxml2argvtest.c: canonicalize the machine type

PCI device assignment is only supported in KVM's fork of qemu, so we
should really detect its availability and give a nice error if its
not supported.
* src/qemu_conf.[ch]: introduce QEMUD_CMD_FLAG_PCIDEVICE indicating
that the -pcidevice command line option is available

to VMs started by older versions of libvirtd.
* src/domain_conf.c: handle formatting and parsing unix monitors
* src/qemu_driver.c: add qemudOpenMonitorUnix(), remove the monitor
pty path searching from qemudFindCharDevicePTYs(), switch

* tests/qemuxml2argvdata/qemuxml2argv-*.args: update test data
There are no functional changes in this patch apart from adding the
monitor type to the state XML.
The patch mostly consists of switching to use virDomainChrDef every
where to describe the monitor.
* src/domain_conf.h: replace monitorpath with monitor_chr
* src/domain_conf.c: handle parsing the monitor type and initializing
monitor chr
* src/qemu_conf.[ch]: make qemudBuildCommandLine take a
virDomainChrDefPtr and use that to build the -monitor parameter

handling code. In particular, if you had a section of XML like:
<disk type='file' device='cdrom'>
<target dev='hdc' bus='ide'/>
<readonly/>
</disk>
This used to work with older libvirt, but now fails. This is because we are
actually passing the literal string (null) to the qemu command-line, which qemu
barfs on. This patch fixes it up by making it blank, which allows qemu to
continue on it's merry way.
