Update test suite accordingly.

VirtualBox uses megabyte, libvirt uses kilobyte.

Add VM name/UUID in log for domain related APIs.
Format: "dom=%p, (VM: name=%s, uuid=%s), param0=%s, param1=%s

VIR_DOMAIN_DEBUG0)

I added a host definition to a network definition:

<network>
  <name>Lokal</name>
  <uuid>2074f379-b82c-423f-9ada-305d8088daaa</uuid>
  <bridge name='virbr1' stp='on' delay='0' />
  <ip address='192.168.180.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.180.128' end='192.168.180.254' />
      <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

With this patch, the XML is correct:

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:

A number of the libvirt APIs require the use of cgroups. This is not
enabled by default on a RHEL6 install. After discussion with cgroups
team, it was decided that upon installation of the libvirt RPM, we
should automatically turn on the cgroups service. This will activate a
default configuration that turns on all cgroups controllers libvirt
requires for full operation.

This patch fixes https://bugzilla.redhat.com/show_bug.cgi?id=664406

If qemu is run as a different uid, it has been unable to access mode
0660 files that are owned by a different user, but with a group that
the qemu is a member of (aside from the one group listed in the passwd
file), because initgroups() is not being called prior to the
exec. initgroups will change the group membership of the process (and
its children) to match the new uid.

To make this happen, the setregid()/setreuid() code in
qemuSecurityDACSetProcessLabel has been replaced with a call to
virSetUIDGID(), which does both of those, plus calls initgroups.

Similar, but not identical, code in qemudOpenAsUID() has been replaced
with virSetUIDGID(). This not only consolidates the functionality to a
single location, but also potentially fixes some as-yet unreported
bugs.

virSetUIDGID() sets both the real and effective group and user of the
process, and additionally calls initgroups() to assure that the
process joins all the auxiliary groups that the given uid is a member
of.

There are cases when we want log an error message, and possibly free
some memory as part of the cleanup, while still preserving errno for a
caller, but the functions that log errors, and virFree (VIR_FREE) make
system calls that will clear errno. This patch preserves errno during
those most basic functions (corresponding to virReportSystemError(),
virReportOOMError(), networkReportError(), etc, as well as
virStrError()). It does *not preserve errno across calls to higher
level items such as virDispatchError(), as it's assumed the caller is
all finished with any need for errno by the time it dispatches the
error.

Running an instance of the router advertisement daemon (radvd) allows
guests using the virtual network to automatically acquire an IPv6
address and default route. Note that acquiring an address only works
for networks with a prefix length of exactly 64 - radvd is still run
in other circumstances, and still advertises routes, but autoconf will
not work because it requires exactly 64 bits of address info from the
network prefix.

This patch avoids a race condition with the pidfile by manually
daemonizing radvd rather than allowing it to daemonize itself, then
creating our own pidfile (in addition to radvd's own file, which is
unnecessary, but there is no way to tell radvd to not create it). This
is accomplished by exec'ing it with "--debug 1" in the commandline,
and using virCommand's features to fork, create a pidfile, and detach
from the newly forked process.

At this point everything is already in place to make IPv6 happen, we just
need to add a few rules, remove some checks for IPv4-only, and document
the changes to the XML on the website.

All of the iptables functions eventually call down to a single
bottom-level function, and fortunately, ip6tables syntax (for all the
args that we use) is identical to iptables format (except the
addresses), so all we need to do is:

1) Get an address family down to the lowest level function in each
   case, either implied through an address, or explicitly when no
   address is in the parameter list, and

2) At the lowest level, just decide whether to call "iptables" or
   "ip6tables" based on the family.

The location of the ip6tables binary is determined at build time by
autoconf. If a particular target system happens to not have ip6tables
installed, any attempts to run it will generate an error, but that
won't happen unless someone tries to define an IPv6 address for a
network. This is identical behavior to IPv4 addresses and iptables.

This patch reorganizes the code in bridge_driver.c to account for the
concept of a single network with multiple IP addresses, without adding
in the extra variable of IPv6. A small bit of code has been
temporarily added that checks all given addresses to verify they are
IPv4 - this will be removed when full IPv6 support is turned on.
