VirtualDisks are .vmdk file based. Other files in a datastore
like .iso or .flp files don't have a UUID attached, fall back
to the path as key for them.

This patch adds support for ethernet interface type to OpenVZ domains
as stated in this previous message: http://www.redhat.com/archives/libvir-
list/2010-July/msg00658.html

* src/vbox/vbox_tmpl.c (vboxAttachDrives): Capture return value.

Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:

  "[datastore] directory/file"

was split into this before:

  datastoreName = "datastore"
  directoryName = "directory"
  fileName = "file"

Now it's split into this:

  datastoreName = "datastore"
  directoryName = "directory"
  directoryAndFileName = "directory/file"

This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.

Update the tests accordingly.

* src/vbox/vbox_tmpl.c (vboxDomainDefineXML): Split...
(vboxSetBootDeviceOrder, vboxAttachDrives, vboxAttachSound)
(vboxAttachNetwork, vboxAttachSerial, vboxAttachParallel)
(vboxAttachVideo, vboxAttachDisplay, vboxAttachUSB): ...into new
helper functions.

* src/lxc/veth.h (vethCreate): Change prototype.
* src/lxc/veth.c (vethCreate): Always malloc veth2, and allocate
veth1 if needed.
(getFreeVethName): Adjust signature, and use virAsprintf.
* src/lxc/lxc_driver.c (lxcSetupInterfaces): Adjust caller.

Distinguish between strings as parameters (const char *)
and strings as return values (char **).

* src/openvz/openvz_conf.c (openvzLocateConfFile): Alter
signature.
(openvzGetVPSUUID, openvzSetDefinedUUID)
(openvzWriteVPSConfigParam, openvzReadVPSConfigParam)
(openvzCopyDefaultConfig): Adjust callers.

* src/openvz/openvz_conf.c: Whitespace fixes.
* src/openvz/openvz_driver.c: Likewise.

* src/conf/network_conf.c (virNetworkAllocateBridge): Avoid
limited buffer from snprintf.

For privileged UML connections (uml:///system), we shouldn't use root's
home dir, but rather somewhere in /var/run/libvirt/uml-guest.

uml_dir overrides user-mode-linux's default of ~/.uml. This is needed
for a couple of different reasons:

libvirt expects this to default to virGetUserDirectory(geteuid()) +
'/.uml'. However, user-mode-linux actually uses the HOME environment
variable to determine where to look for the uml sockets, but if running
libvirtd under sudo (which I routinely do during development), $HOME is
pointing at my user's homedir, while my euid is 0, so libvirt looks in
/root.

Also (and this was my actual motivation for this patch), if HOME isn't
set at all, user-mode-linux utterly fails. Looking at the code, it seems
it's meant to emit a warning, but alas, it doesn't for some reason.
If running libvirtd from upstart, HOME is not set, so any system using
upstart will need this change.

Xen4.0 includes a new blktap2 implementation, which is specified
with 'tap2' prefix.  AFAICT it's configuration syntax is identical
to blktap, with exception of 'tap2' vs 'tap' prefix.  This patch
takes the simple approach of accepting and generating sexp
containing 'tap2' prefix.

Take care of escaping '"' and '|' (the escape character).

Add tests for this.

virHexToBin will be used in the .vmx handling code.

When creating a new domain from XML, the check for an existing
domain name should compare the return of the function to a valid
LPAR ID (!= -1) and not to error (== -1).

The check was altered in 8c48743b
and got too strict, I've no clue how that snuck in. This check
makes every try to open a connection using the ESX driver fail
with an invalid argument error.

Revert the change to the check and add a comment to prevent future
mistakes with this check.

This allows to list existing volumes and to retrieve information
about them.

UML supports hot plugging and unplugging of various devices. This patch
exposes this functionality for disks.

Other drivers will need this same functionality, so move it to up to
conf/domain_conf.c and give it a more general name.

When finding a sparse NUMA topology, libnuma will return ENOENT
the first time it is invoked. On subsequent invocations it
will return success, but with an all-1's CPU mask. Check for
this, to avoid polluting the capabilities XML with 4096 bogus
CPUs

* src/nodeinfo.c: Check for all-1s CPU mask

Enabling debug doesn't show the capabilities XML for a connection.
Add an extra debug statement for the return value

* src/libvirt.c: Enable debug logging of capabilities XML

Like the comment suggested, we just open the file and pass the file
descriptor to uml. The input "stream" is set to "null", since I couldn't
find any useful way to actually use a file for input for a chardev and
this also mimics what e.g. QEmu does internally.

Instead of using one big traversal spec for lookup use a set of
more fine grained traversal specs that are selected based on the
actual needs of the lookup.

This gives up to 20% speedup for certain operations like domain
listing due to less HTTP(S) traffic.

* src/xenapi/xenapi_driver.c (xenapiDomainGetInfo): Avoid using
XEN_VM_POWER_STATE_UNKNOWN, which disappeared in newer xenapi.
* src/xenapi/xenapi_utils.c (mapPowerState): Likewise.

Previously QEMU enabled KQEMU by default and had -no-kqemu.
0.11.x switched to requiring -enable-kqemu. 0.12.x dropped
kqemu entirely. This patch adds support for -enable-kqemu
so 0.11.x works. It replaces a huge set of if() with a
switch() to make the code a bit more readable.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Support
  -enable-kqemu

With the previous storage pool UUID source not all storage pools
had a proper UUID, especially GSX storage pools. The mount path
is unique per host and cannot change during the lifetime of the
datastore. Therefore, it's MD5 sum can be used as UUID.

Use gnulib's crypto/md5 module to generate the MD5 sum.

Xen supports on_crash actions coredump-{destroy,restart}.  libvirt
cannot parse config returned by xend that contains either of these
actions

xen52 # xm li -l test | grep on_crash
    (on_crash coredump-restart)
xen52 # virsh dumpxml test
error: internal error unknown lifecycle type coredump-restart

This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.

We already filled the PCI address structure when we checked whether it's
free or not, so let's just use the structure here instead of filling it
again.

I wrote a patch to add support for listing the Vendor and Model of a
storage pool in the storage pool XML.  This would allow vendor
extensions of specific devices.  The patch includes a test for the new
attributes as well.
