On Fedore 14, virt-manager spews a bunch of warnings to the console:

/usr/lib64/python2.7/site-packages/libvirt.py:1781: PendingDeprecationWarning: The CObject type is marked Pending Deprecation in Python 2.7.  Please use capsule objects instead.

Have libvirt use the capsule API if available. I've verified this compiles
fine on older python (2.6 in RHEL6 which doesn't have capsules), and
virt-manager seems to function fine.

Make it easy to change debugging if being used by a client program.

After the remote driver runs an event callback, it unconditionally disables the
loop timer, thinking it just flushed every queued event. This doesn't work
correctly though if an event is queued while a callback is running.

The events actually aren't being lost, it's just that the event loop didn't
think there was anything that needed to be dispatched. So all those 'lost
events' should actually get re-triggered if you manually kick the loop by
generating a new event (like creating a new guest).

The solution is to disable the dispatch timer _before_ we invoke any event
callbacks. Events queued while a callback is running will properly reenable the
timer.

The current security driver usage requires horrible code like

    if (driver->securityDriver &&
        driver->securityDriver->domainSetSecurityHostdevLabel &&
        driver->securityDriver->domainSetSecurityHostdevLabel(driver->securityDriver,
                                                              vm, hostdev) < 0)

This pair of checks for NULL clutters up the code, making the driver
calls 2 lines longer than they really need to be. The goal of the
patchset is to change the calling convention to simply

  if (virSecurityManagerSetHostdevLabel(driver->securityDriver,
                                        vm, hostdev) < 0)

The first check for 'driver->securityDriver' being NULL is removed
by introducing a 'no op' security driver that will always be present
if no real driver is enabled. This guarentees driver->securityDriver
!= NULL.

The second check for 'driver->securityDriver->domainSetSecurityHostdevLabel'
being non-NULL is hidden in a new abstraction called virSecurityManager.
This separates the driver callbacks, from main internal API. The addition
of a virSecurityManager object, that is separate from the virSecurityDriver
struct also allows for security drivers to carry state / configuration
information directly. Thus the DAC/Stack drivers from src/qemu which
used to pull config from 'struct qemud_driver' can now be moved into
the 'src/security' directory and store their config directly.

* src/libvirt.c: Add missing debug for security APIs

If invalid type is specified, e.g.
<serial type='foo'>
    <target port='0'/>
</serial>

We replace 'foo' with "null" type implicitly, without reporting an
error message to tell the user, and "start" or "edit" the domain
will be success.

It's not good to guess what the user wants, This patch is to fix
the problem.

* src/conf/domain_conf.c

Setting unix_sock_group to something else than default "root" in
/etc/libvirt/libvirtd.conf prevents system libvirtd from dumping core on
crash. This is because we used setgid(unix_sock_group) before binding to
/var/run/libvirt/libvirt-sock* and setgid() back to original group.
However, if a process changes its effective or filesystem group ID, it
will be forbidden from leaving core dumps unless fs.suid_dumpable sysctl
is set to something else then 0 (and it is 0 by default).

Changing socket's group ownership after bind works better. And we can do
so without introducing a race condition since we loosen access rights by
changing the group from root to something else.

and keep it enabled by default. This allows downstreams to turn it off
via:

./configure --disable-maintainer-mode

I added a host definition to a network definition:

<network>

  <bridge name='virbr1' stp='on' delay='0' />

      <host mac='23:74:00:03:42:02' name='somevm' ip='192.168.180.10' />
    </dhcp>
  </ip>
</network>

But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get
added to the dnsmasq command. The patch below fixes it for me.

The warning is bogus since strtok_r doesn't use the value when it's
first called and initializes it for the following calls.

When dynamic_ownership=0, saved images must be owned by the same uid
as is used to run the qemu process, otherwise restore won't work. To
accomplish this, qemuSecurityDACRestoreSavedStateLabel() needs to
simply return when it's called.

This fix is in response to:

Although the upper-layer code protected against it, it was possible to
call iptablesForwardMasquerade() with an IPv6 address and have it
attempt to add a rule to the MASQUERADE chain of ip6tables (which
doesn't exist).

This patch changes that function to check the protocol of the given
address, generate an error log if it's not IPv4 (AF_INET), and finally
hardcodes all the family parameters sent down to lower-level functions.

This is partially in response to

  https://bugzilla.redhat.com/show_bug.cgi?id=653300

The crash in that report was coincidentally fixed when we switched
from using inet_pton() to using virSocketParseAddr(), but the absence
of an ip address in a dhcp static host definition was still silently
ignored (and that entry discarded from the saved XML). This patch
turns that into a logged failure; likewise if the entry has neither a
mac address nor a name attribute (the entry is useless without at
least one of those, plus an ip address).

Since the network name is now pulled into this function in order for
those error logs to be more informative, the other error messages in
the function have also been changed to take advantage.

Also added explicit links to the subscription and
archive pages for the user and developer mailing
lists.

While doing some testing with Qemu and creating huge logfiles I encountered the case where the VM could not start anymore due to the lseek() to the end of the Qemu VM's log file failing. The patch below fixes the problem by replacing the previously used 'int' with 'off_t'.

To reproduce this error, you could do the following:

dd if=/dev/zero of=/var/log/libvirt/qemu/<name of VM>.log bs=1024 count=$((1024*2048))

and you should get an error like this:

error: Failed to start domain <name of VM>
error: Unable to seek to -2147482651 in /var/log/libvirt/qemu/<name of VM>.log: Success

The udev driver does not update a PCI device with its SR-IOV capabilities,
when applicable, the way the hal driver does.  As a result, dumping the
device's XML will not include the relevant physical or virtual function

As pointed out in https://bugzilla.redhat.com/show_bug.cgi?id=659855#c9,
commit c3568ec2 introduced a regression where we no longer close any
fd's beyond FD_SETSIZE.

* src/util/util.c (__virExec): Continue to close fd's beyond
keepfd range.
Reported by Stefan Praszalowicz.

The original version of these functions would modify the address sent
in, meaning that the caller would usually need to copy the address
first. This change makes the original a const, and puts the resulting
masked address into a new arg (which could point to the same
virSocketAddr as the original, if the caller really wants to modify
it).

This also makes the API consistent with virSocketAddrBroadcast[ByPrefix].

Previously we used ioctl() to set the IP address and netmask of the
bridges used for virtual networks, and apparently the SIOCSIFNETMASK
ioctl implicitly set the broadcast address for the interface. The new
method of using the "ip" command requires broadcast address to be
explicitly specified though.

These functions work only for IPv4, becasue IPv6 doesn't have the same
concept of "broadcast address" as IPv4. They merely OR the inverse of
the netmask with the given host address, thus turning on all the host
bits.

Also include some whitespace changes. No functional change included.

Add vboxArrayGetWithUintArg to handle new signature variations. Also
refactor vboxArrayGet* implementation to use a common helper function.

Deal with the incompatible changes in the VirtualBox 4.0 API. This
includes major changes in virtual machine and storage medium lookup,
in RDP server property handling, in session/lock handling and other
minor areas.

VirtualBox 4.0 also dropped the old event API and replaced it with a
completely new one. This is not fixed yet and will be addressed in
another patch. Therefore, currently the domain events are supported
for VirtualBox 3.x only.

Based on initial work from Jean-Baptiste Rouault.

VIR_ERR_INVALID_DOMAIN is meant for invalid domain pointers.
VIR_ERR_NO_DOMAIN is meant for non-existing domains.

On Windows IID's are represented as GUID by value, instead of nsID
by reference on non-Windows platforms.

Patch the vbox_CAPI_v2_2.h header to deal with this difference.

Rewrite vboxIID abstraction that deals with the different IID
representations. Add support for the GUID representation. Also unify
the four context dependent free functions for vboxIIDs

  vboxIIDUnalloc, vboxIIDFree, vboxIIDUtf8Free, vboxIIDUtf16Free

into vboxIIDUnalloc that is now safe to be called (even multiple
times) on a vboxIID independent of the source and context of the
vboxIID.

The new vboxIID is designed to be used as a stack allocated variable.
It has a value member that represents the actual IID value.

When I build libvirt without libvirtd, I receive some errors:
cp: cannot stat `/home/wency/rpmbuild/BUILDROOT/libvirt-0.8.6-1.el6.x86_64/etc/libvirt/qemu/networks/default.xml': No such file or directory

My build step:
# ./autogen.sh --without-libvirtd
# make dist
# rpmbuild --nodeps --define "_sourcedir `pwd`" --define "_without_libvirtd 1" -ba libvirt.spec

The reason is we disable network when we do not build libvirt daemon in configure.ac.
After fixing this bug, I build libvirt without libvirtd, I receive other errors:
