Subject: [PATCH] chown kernel/initrd before spawning qemu
If we're running qemu unprivileged, we need to chown any supplied kernel
or initrd before spawning it.
* src/qemu_driver.c: rename qemuDomainSetDiskOwnership() to
qemuDomainSetFileOwnership(), pass it a path string instead of a disk
definition and use it for chowning the kernel/initrd in
qemuDomainSetAllDeviceOwnership()
(cherry picked from commit c42b39784534930791d1feb3de859d85a7848168)

Subject: [PATCH] Handle kernels with no ipv6 support
If the ipv6 kernel module is not loaded, then we get this when starting
a virtual network:
libvir: Network Config error :
cannot enable /proc/sys/net/ipv6/conf/virbr0/disable_ipv6:
No such file or directory
If disable_ipv6 is not present, we should just merrily continue on our
way.
* src/network_driver.c: make networkDisableIPV6() not fail if the kernel
has no ipv6 support

Subject: [PATCH] Make LXC / UML drivers robust against NUMA topology brokenness
Some kernel versions expose broken NUMA topology for some machines.
This causes the LXC/UML drivers to fail to start. QEMU driver was
already fixed for this problem
* src/lxc_conf.c: Log and ignore failure to populate NUMA info
* src/uml_conf.c: Log and ignore failure to populate NUMA info
* src/capabilities.c: Reset nnumaCell to 0 after freeing

From 332979bb680d833529ab9cecac6828c6ce54d731 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add host PCI device hotplug support
Attaching a host PCI device to a qemu guest is done with a
straightforward 'pci_add pci_addr auto host host=XX:XX.X' command.
Like with NIC and disk hotplug, we need to retain the guest PCI address
assigned by qemu so that we can use it for hot-unplug.
Identifying a device for detach is done using the host PCI address.
Managed mode is handled by detaching/resetting the device before
attaching it to the guest and re-attaching it after detaching it from
the guest.

Subject: [PATCH] Cosmetic change to 'virsh nodedev-list --tree' output
Maybe it's just me, but I try to select an item from the tree using
double-click and get annoyed when "+-" gets included in the selection.
* src/virsh.c: add a space between "+-" and the node device name
in 'virsh nodedev-list --tree'
(cherry picked from commit 097c818bf00b3777778ffc32fea3a6ed1e741e2b)

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] 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] 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()
