Subject: [PATCH] Detect newer qemu-kvm versions
The KVM version string can be one of the following:
- qemu-kvm-x.y.z in stable releases
- kvm-XX for kvm versions up to kvm-85
- qemu-kvm-devel-XX for kvm version kvm-86 and later
There are only a few of places where we need to detect
differences between KVM versions based on 0.9.1:
1) VNET_HDR introduced in kvm-74
2) -incoming tcp introduced in kvm-79
3) -incoming exec introduced in kvm-80
4) -incoming stdio in all earlier kvm versions
With qemu-kvm-0.10.x, we can now assume that (1) is available
if it's a KVM release, (2) and (3) is always available and
(4) is never available.
So, from now on we should only need to check the qemu version
number and the "is_kvm" flag for detecting feature availability.
We only need the KVM version number for older releases.

Subject: [PATCH] Don't log monitor output to domain log file.
It's logged via the logging system already. Prefix monitor debug output with vm
name.

Subject: [PATCH] Don't unnecessarily try to change a file context
As pointed out by Tim Waugh here:
https://bugzilla.redhat.com/507555
We shouldn't bother trying to set the context of a file if it already
matches what we want.
(Fixed to use STREQ() and not use tabs, as pointed out by danpb)

Subject: [PATCH] Re-factor qemu version parsing
This patch is purely re-factoring without any functional changes
to make way for the next patch.
The main thing achieved by the refactoring is that we now have
easier access to the parenthesised string that KVM folks seem
to delight in changing.

Subject: [PATCH] Fix qemu driver's interpretation of <hostdev managed='yes'/>
This change:
Tue Mar 3 08:55:13 GMT 2009 Daniel P. Berrange <berrange@redhat.com>
Don't try to detach & reset PCI devices while running test
suite for XML-> ARGV conversion.
* src/qemu_driver.c: Add qemuPrepareHostDevices() helper to
detach and reset PCI devices.
* src/qemu_conf.c: Don't detach & reset PCI devices while
building the command line argv
accidentally did this:
- if (hostdev->managed) {
+ if (!hostdev->managed) {
Which results in managed='yes' not causing the device to be
detached when the guest is starting.

Subject: [PATCH] Maintain a list of active PCI hostdevs and use it in pciResetDevice()
https://bugzilla.redhat.com/499678
First we add a pciDeviceList type and add a qemuGetPciHostDeviceList()
function to build a list from a domain definition. Use this in
prepare/re-attach to simplify things and eliminate the multiple
pciGetDevice() calls.
Then, as we start/shutdown guests we can add or delete devices as
appropriate from a list of active devices.
Finally, in pciReset(), we can use this to determine whether its safe to
reset a device as a side effect of resetting another device.

Subject: [PATCH] Allow PM reset on multi-function PCI devices
https://bugzilla.redhat.com/515689
It turns out that a PCI Power Management reset only affects individual
functions, and not the whole device.
The PCI Power Management spec talks about resetting the 'device' rather
than the 'function', but Intel's Dexuan Cui informs me that it is
actually a per-function reset.
Also, Yu Zhao has added pci_pm_reset() to the kernel, and it doesn't
reject multi-function devices, so it must be true! :-)
(A side issue is that we could defer the PM reset to the kernel if we
could detect that the kernel has PM reset support, but barring version
number checks we don't have a way to detect that support)
* src/pci.c: remove the pciDeviceContainsOtherFunctions() check from
pciTryPowerManagementReset() and prefer PM reset over bus reset
where both are available
Cc: Cui, Dexuan <dexuan.cui@intel.com>
Cc: Yu Zhao <yu.zhao@intel.com>

Subject: [PATCH] Allow control over QEMU audio backend
When using VNC for graphics + keyboard + mouse, we shouldn't
then use the host OS for audio. Audio should go back over
VNC.
When using SDL for graphics, we should use the host OS for
audio since that's where the display is. We need to allow
certain QEMU env variables to be passed through to guest
too to allow choice of QEMU audio backend.
* qemud/libvirtd.sysconf: Mention QEMU/SDL audio env vars
* src/qemu_conf.c: Passthrough QEMU/SDL audio env for SDL display,
disable host audio for VNC display

Subject: [PATCH] Run 'cont' on successful migration finish.
https://bugzilla.redhat.com/516187
As of qemu 0.10.6, qemu now honors the -S flag on incoming migration.
That means that when the migration completes, we have to issue a
'cont' command to get the VM running again. We do it unconditionally
since it won't hurt on older qemu.

Subject: [PATCH] Improve PCI host device reset error message
https://bugzilla.redhat.com/499678
Currently, if we are unable to reset a PCI device we return a fairly
generic 'No PCI reset capability available' error message.
Fix that by returning an error from the individual reset messages and
using that error to construct the higher level error mesage.
* src/pci.c: set errors in pciTryPowerManagementReset() and
pciTrySecondaryBusReset() on failure; use those error messages
in pciResetDevice(), or explain that no reset support is available
(cherry picked from commit ebea34185612c3b96d7d3bbd8b7c2ce6c9f4fe6f)

Subject: [PATCH] Create /var/log/libvirt/{lxc,uml} dirs
Otherwise logrotate barfs:
error: error accessing /var/log/libvirt/uml: No such file or directory
error: libvirtd:1 glob failed for /var/log/libvirt/uml/*.log
error: found error in /var/log/libvirt/qemu/*.log /var/log/libvirt/uml/*.log /var/log/libvirt/lxc/*.log , skipping
* qemud/Makefile.am: always create /var/log/libvirt/{lxc,uml} when
installing the logrotate conf; not ideal, but easier than making
the logrotate conf depend on which drivers are enabled

Subject: [PATCH] Reset and re-attach PCI host devices on guest shutdown
https://bugzilla.redhat.com/499561
When the guest shuts down, we should attempt to restore all PCI host
devices to a sane state.
In the case of managed hostdevs, we should reset and re-attach the
devices. In the case of unmanaged hostdevs, we should just reset them.
Note, KVM will already reset assigned devices when the guest shuts
down using whatever means it can, so we are only doing it to cover the
cases the kernel can't handle.
* src/qemu_driver.c: add qemuDomainReAttachHostDevices() and call
it from qemudShutdownVMDaemon()
(cherry picked from commit 4035152a8767e72fd4e26a91cb4d5afa75b72e61)
