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

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

snprintf is currently implicitly picked up by getaddrinfo, but we
might as well make it explicit so that mingw doesn't break if
getaddrinfo changes to drop the dependency.

func doesn't matter for gcc compilation, but may help other compilers
cope with our use of __func__.

* bootstrap.conf (gnulib_modules): Add snprintf and func.

Virsh shouldn't check for driver support but rather let the backend handled this.
After removing the check, I can successfully attach file-based images to a qemu
VM with attach-disk.

% virsh attach-disk vm2 /images/test02.img vdc --driver qemu --type disk --subdriver raw
Disk attached successfully

This command generates the following XML:

<disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/images/test02.img'/>
      <target dev='vdc' bus='virtio'/>
      <alias name='virtio-disk2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>

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.

xml2sexpr and sexpr2xml tests for blktap2

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.

Since libvirt-guests init script and its configuration do not require
libvirtd to be running/installed, it was a bad idea to put them into
daemon directory. libvirt.spec even includes these files in
libvirt-client subpackage, which may result in build failure for
client-only builds when the whole daemon directory is just skipped.

When building libvirt RPM without macvtap, with_libnl would be
undefined.

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

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

Enabling debug doesn't show the capabilities XML for a connection.

When failing to serialize the normal RPC reply, try harder to
send a error message back to the client, instead of immediately
closing the connection.

When libvirtd fails to serialize a message to XDR the client
connection is terminated immediately. To enable this to be
diagnosed, log the message which caused the problem on the
server

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.

RHEL-5 Xen doesn't support the old style vnc configuration. In sexpr, we
can't really check it with rhel5-api turned on. However, for XM
configuration files it's sufficient to use cfg version 1 instead of 2.

This caused unnecessary make check failures when libvirt is configured
--with-rhel5-api

The most common cause of errors with rhel5-api turn on was missing
"(type ioemu)" in sexpr or its equivalent in XM configuration file. This
happens because the presence of that part in sexpr (or cfg) depends on
xen version the host is running. Let's avoid it by explicitly specifying
interface model which ensures "type ioemu" will always be emitted.

This patch adds

    <model type='e1000'/>

withing the interface element in all affected xml files. And

    (model 'e1000')

to all corresponding sexpr files with similar fix to cfg files. Such
configuration works regardless on Xen version.

If linuxNodeInfoCPUPopulate() fails, the test would just print "FAILED"
which is not very informative. It's better to print the real error.

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

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
