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 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)
(cherry picked from commit add254feeaa830dd5af1118c141cb140bf55b5a7)

Subject: [PATCH] qemu -drive takes format= not fmt=
Seems like a simple typo - it has been "format=" since the flag
was introduced, but we added it as "fmt=".

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.
(cherry picked from commit 1d6c713b18741f1a0e3d0ccd094275a11aef138c)

daemon: Export SDL audio environment variables
/etc/sysconfig/libvirtd has a few environment variables for configuring
libvirt SDL audio. The libvirtd process doesn't see these, however, because
they are never exported. Let's export the variables after sourcing the
sysconfig script.
There is another problem here that the commented out values in the
sysconfig script are not neccessarily the actual defaults, we are qemus
mercy here. Not sure how to solve that.

qemu: Allow using regular audio backends with VNC
Currently all host audio backends are disabled if a VM is using VNC, in
favor of the QEMU VNC audio extension. Unfortunately no released VNC
client supports this extension, so users have no way of getting audio
to work if using VNC.
Add a new config option in qemu.conf which allows changing libvirt's
behavior, but keep the default intact.
v2: Fix doc typos, change name to vnc_allow_host_audio

Fix CDROM media change for QEMU when using -device syntax
Disk devices in QEMU have two parts, the guest device and the host
backend driver. Historically these two parts have had the same
"unique" name. With the switch to using -device though, they now
have separate names. Thus when changing CDROM media, for guests
using -device syntax, we need to prepend the QEMU_DRIVE_HOST_PREFIX
constant
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add helper function
qemuDeviceDriveHostAlias() for building a host backend alias
* src/qemu/qemu_driver.c: Use qemuDeviceDriveHostAlias() to determine
the host backend alias for performing eject/change commands in the
monitor

Subject: [PATCH] Use fsync() at the end of file allocation instead of O_DSYNC
Instead of opening storage file with O_DSYNC, make sure data are written
to a disk only before we claim allocation has finished.

Trivial virsh.pod additions --all for "list" command and similar
This is just a trivial patch to virsh.pod (from git master). It adds the
following pieces to the virsh man page:
+ Shows the --inactive and --all optional parameters for the list
command.
Closes Bugzilla #575512, reported by Renich Bon Ciric
https://bugzilla.redhat.com/show_bug.cgi?id=575512
+ Corrects the existing description of the list command, to now say
that only running domains are listed if no domains are specified.
The man page up until this point has said all domains are listed if
no domains are specified, which is incorrect.
+ Adds the "shut off" state to the list of states for the list
command.
+ Adds a missing =back around line 755, that pod2man was complaining
was missing.

network: bridge: Don't start network if it collides with host routing
Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=235961
If using the default virtual network, an easy way to lose guest network
connectivity is to install libvirt inside the VM. The autostarted
default network inside the guest collides with host virtual network
routing. This is a long standing issue that has caused users quite a
bit of pain and confusion.
On network startup, parse /proc/net/route and compare the requested
IP+netmask against host routing destinations: if any matches are found,
refuse to start the network.
v2: Drop sscanf, fix a comment typo, comment that function could use
libnl instead of /proc
v3: Consider route netmask. Compare binary data rather than convert to
string.
v4: Return to using sscanf, drop inet functions in favor of virSocket,
parsing safety checks. Don't make parse failures fatal, in case
expected format changes.
v5: Try and continue if we receive unexpected. Delimit parsed lines to
prevent scanning past newline

commit e984019688509605966c03cd77f4591d2cc222d3
Author: Cole Robinson <crobinso@redhat.com>
Date: Fri Apr 30 18:14:35 2010 +0200
domain: Fix PCI address decimal parsing regression
<hostdev> address parsing previously attempted to detect the number
base: currently it is hardcoded to base 16, which can break PCI
assignment via virt-manager. Revert to the previous behavior.
* src/conf/domain_conf.c: virDomainDevicePCIAddressParseXML, switch to
virStrToLong_ui(bus, NULL, 0, ...) to autodetect base

commit 83be64034a0b530c904ceb4fd1ed1c10b5cdf4bf

qemu: Report cmdline output if VM dies early
qemuReadLogOutput early VM death detection is racy and won't always work.
Startup then errors when connecting to the VM monitor. This won't report
the emulator cmdline output which is typically the most useful diagnostic.
Check if the VM has died at the very end of the monitor connection step,
and if so, report the cmdline output.

* Moved case of DEVTYPE == "wlan" up as it's definitive that we have a network interface.
* Made comment more detailed about the wired case to explain better
how it differentiates between wired network interfaces and USB

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.

From d79f35fbd4eaf610972621b042993d00f3247d5c Mon Sep 17 00:00:00 2001
From: Mark McLoughlin <markmc@redhat.com>
Date: Fri, 14 Aug 2009 08:31:11 +0100
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>
(cherry picked from commit 64a6682b93a2a8aa38067a43979c9eaf993d2b41)

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] 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()
