85453c4247 Add support for attaching network/bridge NICs in QEMU driver
In order to hotplug a network/bridge backed NIC, we need to first create
the tap file descriptor, add the tap interface to the bridge and then
pass the file descriptor to the qemu process using the 'getfd' monitor
command.

Once the tapfd has been accepted, we create the network backend using
host_net_add, supplying the name assigned to the tapfd. If this fails,
we need to close the tapfd in qemu using the 'closefd' monitor command.

If the version of qemu does not support the getfd/closefd monitor
commands we detect "unknown command" in the getfd reply and fail the
attach operation.

* src/qemu_driver.c: add support for tapfd based hotplug in
  qemudDomainAttachNetDevice()

1daaebfa0c Add SCM_RIGHTS support to QEMU monitor code
Add qemudMonitorCommandWithFd() which allows a file descriptor to be
sent to qemu over a unix monitor socket using SCM_RIGHTS. See the
unix(7) and cmsg(3) man pages.

* src/qemu_conf.c: add a scm_fd param to qemudMonitorCommandExtra(),
  add qemudMonitorCommandWithFd(), implement SCM_RIGHTS support in
  qemudMonitorSendUnix()

7d9576edcb Use sendmsg() on QEMU monitor socket
Switch from using write() to using sendmsg() on QEMU's monitor socket
so that we can add support for SCM_RIGHTS.

* src/qemu_driver.c: add sendmsg() based qemudMonitorSendUnix() and use
  it when the monitor fd is a unix socket
2009-07-27 15:31:51 +01:00

9de2972c30 Factor qemudMonitorSend() out of qemudMonitorCommandExtra()
Add a little helper function to write the monitor command followed by
carriage return in a single write.

This doesn't make any real difference, but allows us to more easily
switch to using sendmsg() when using the monitor over a unix socket.

* src/qemu_conf.c: split qemudMonitorSend() out

be44cabd7f Clean up error handling in qemudDomainAttachNetDevice()
In subsequent patches we're going to have a file descriptor to close
too, so centralize the error handling cleanups to make things easier.

  error handling cleanups together

32db8dd75b Make qemuBuildHostNetStr() take tapfd as a string
With hotplug, we're going to want to pass a tapfd name rather than an
actual file descriptor, so prepare the way by passing a string tapfd to
qemuBuildHostNetStr().

* src/qemu_conf.h: qemuBuildHostNetStr() takes a string tapfd now

* src/qemu_conf.c: pass qemuBuildHostNetStr() a string rather than an
  actual file descriptor

* src/qemu_driver.c: update qemudDomainAttachNetDevice() for change

707302b2cf Only probe qemu for machine types when binary changes
By probing for qemu machine types, we increased the time of a
GetCapabilities call from 100us to a whopping 60ms.

This patch takes the approach of only probing for machine types
when the mtime of the emulator binary changed since the last time
the capabilities were generated.

* src/capabilities.h: cache the emulator binary mtime

* src/qemu_conf.c: add qemudGetOldMachines() to copy the machine
  types from the old caps struct if the mtime for the binary hasn't
  changed

* src/qemu_conf.h, src/qemu_driver.c: pass the old caps pointer to
  qemudCapsInit()

c14c6b083e Probe QEMU directly for machine aliases if not found in capabilties
Not all possible emulators are actually in the capabilities, so if we
don't find the supplied emulator we should probe it directly for machine
types.

* src/qemu_driver.c: add qemudCanonicalizeMachineDirect() to directly
  probe an emulator for the canonical machine type

be291b330a Canonicalize qemu machine types
In qemu-0.11 there is a 'pc-0.10' machine type which allows you to run
guests with a machine which is compatible with the pc machine in
qemu-0.10 - e.g. using the original PCI class for virtio-blk and
virtio-console and disabling MSI support in virtio-net. The idea here
is that we don't want to suprise guests by changing the hardware when
qemu is updated.

I've just posted some patches for qemu-0.11 which allows libvirt to
canonicalize the 'pc' machine alias to the latest machine version.

This patches makes us use that so that when a guest is configured to
use the 'pc' machine type, we resolve that to 'pc-0.11' machine and
save that in the guest XML.

* src/qemu_conf.c: add qemudCanonicalizeMachine() to canonicalize
  the machine type according to the machine aliases in capabilities

* src/qemu_driver.c: parse aliases in qemudParseMachineTypesStr()

38fd207e53 Add virCapsGuestMachine structure
A subsequent commit will add a "canonical" field to this structure,
this patch basically just prepares the way for that.

The new type is added, along with virCapabilitiesAlloc/FreeMachines()
helpers and a whole bunch of code to make the transition.

One quirk is that virCapabilitiesAddGuestDomain() and
virCapabilitiesAddGuest() take ownership of the machine list rather
than duping it. This makes sense to avoid needless copying.

* src/capabilities.h: add the virCapsGuestMachine struct and use it
  in virCapsGuestDomainInfo, add prototypes for new functions and
  update the AddGuest() prototypes

* src/capabilities.c: add code for allocating and freeing the new
  type, change the machines parameter to AddGuest() etc.

* src/libvirt_private.syms: export the new helpers

* src/qemu_conf.c: update all the machine type code to use the new
  struct

* src/xen_internal.c: ditto

* tests/testutilsqemu.c: ditto

d412487eb7 Probe for QEMU machine types
Currently we hardcode the QEMU machine types. We should really just
parse the output of 'qemu -M ?' so the lists don't get out of sync.

xenner doesn't support '-M ?', so we still need to hardcode that.

The horrible (const char *const *) is removed in a subsequent patch.

* src/qemu_conf.c: kill the arch_info*machines tables, retain the
  hardcoded xenner machine type, add qemudProbeMachineTypes() to
  run and parse 'qemu -M ?' and use it in qemudCapsInitGuest()

13f3d40cbf Don't allow NULL paths for BlockStats and InterfaceStats
Do the check in libvirt.c, to save drivers from the burden. This changes
behavior slightly in the qemu driver: we no longer explictly error if
passed an empty string. An error will still be thrown when the device
lookup fails.
