e65667c0c6 Ensure system identity includes process start time
The polkit access driver will want to use the process start
time field. This was already set for network identities, but
not for the system identity.

7ab7c9a2e9 VMX: Add a VMWare Fusion 5 configuration for tests
A user was having an issue with this specific VMWare Fusion config and
he gave me permission to add it as part of our test suite to further
expand our VMX test coverage. Unfortunately our VMX parser and
generator does not support many features contained within and just
silently ignores fields it does not understand so they had to
be removed out in the xml2vmx test. The original unmodified version
exists in the vmx2xml test.

834aebcc2f VMX: Add support for 'auto detect' fileNames
VMWare Fusion 5 can set the CD-ROM's device name to be 'auto detect' when
using the physical drive via 'cdrom-raw' device type. VMWare will then
connect to first available host CD-ROM to the virtual machine upon start
up according to VMWare documentation. If no device is available, it
appears that the device will remain disconnected.

To better model this a CD-ROM that is marked as "auto detect" when in
the off state would be modeled as the following with this patch:
  <disk type='block' device='lun'>
    <source startupPolicy='optional'/>
    <target dev='hda' bus='ide'/>
    <address type='drive' controller='0' bus='0' target='0' unit='0'/>
  </disk>

Once the domain transitions to the powered on state, libvirt can
populate the remaining source data with what is connected, if anything.
However future power cycles, the domain may not always start with that
device attached.

4b5652d0dc Allow <source> for type=block to have no dev
Currently the XML parser already allows the following syntax:
  <disk type='block' device='cdrom'>
    <source startupPolicy='optional'/>
    <target dev='hda' bus='ide'/>
    <address type='drive' controller='0' bus='0' target='0' unit='0'/>
  </disk>

But it if the dev value is NULL then it would not have the leading
"<source ", resulting in invalid XML.

caf6589233 build: skip ld_preload tests on non-Linux systems
A cross build to mingw fails with:

  CC       virsystemdtest-virsystemdtest.o
../../tests/virsystemdtest.c: In function 'testCreateNoSystemd':
../../tests/virsystemdtest.c:97:9: error: implicit declaration of function 'unsetenv' [-Werror=implicit-function-declaration]

../../tests/virsystemdtest.c:97:9: error: nested extern declaration of 'unsetenv' [-Werror=nested-externs]

We could cop out and pull in the gnulib unsetenv module.  But when
you stop and think about it, this test requires LD_PRELOAD to work,
and systemd is a Linux-only concept anyways, both of which mean
the test could never work on mingw in the first place.  Simpler is
to just fix the test to behave like our other LD_PRELOAD tests.

0e1f012c1d build: hoist system-specific checks before library checks
Commit f92c7e3 fixed a regression for native builds, but introduced
a regression for cross-compilation builds; in particular,
./autobuild.sh on a Fedora system with mingw cross-compiler fails
with:

checking for qemu-kvm... /usr/bin/qemu-kvm
checking for yajl_parse_complete in -lyajl... no
checking for yajl_tree_parse in -lyajl... no
configure: error: You must install the libyajl library & headers to compile libvirt

Since we default $with_qemu to 'yes' rather than 'check', and then
flip that default based on platform-specific checks, those platform
specifics need to come prior to any library checks that depend on
the value of $with_qemu.

* configure.ac: Ensure system defaults are sane before checking
for things that make decisions based on system default.

716c7bb1dd build: fix VPATH build of remote driver
Commit 073e1575 tried to set things up so that 1) generated files
to be shipped in the tarball always live in srcdir, and 2) we have
no files in SOURCES that depend on any other files with a literal
$(srcdir) in the name, because that situation can cause confusing
results for the make expansion of $@ depending on whether the file
is found locally or via VPATH.  But all my testing for that patch
was done incrementally, where all the protocol.[ch] files had
already been generated prior to the patch and were up-to-date in
the srcdir, and thus I missed one case where $@ causes grief in a
VPATH build from a fresh checkout:

We have a pattern rule for generating remote_protocol.[ch], and
what's more, the rule for protocol.c depends on protocol.h AND
on the protocol.x file.  The pattern for protocol.c is only
satisfied via the VPATH lookup for protocol.x, and if protocol.h
doesn't yet exist, the VPATH rule kicks in and we end up with a
dependency on a file with $(srcdir) in the name.  Based on make's
rules for $@, this resulted in make building remote_protocol.h
into srcdir (where we want it), then remote_protocol.c into
builddir (oops, not so good for the tarball), and also causes
the build to fail (the compiler can't find the .h if it lives
in a different directory than the .c):

  CC       remote/libvirt_driver_remote_la-remote_protocol.lo
remote/remote_protocol.c:7:29: fatal error: remote_protocol.h: No such file or directory
 #include "remote_protocol.h"
                             ^
compilation terminated.

As before, the fix is to hard-code the output file to go into
srcdir in spite of $@; but since this is in a pattern rule, we
are forced to use $@ in the recipe, so the patch is a bit
trickier than what was done in commit 073e1575.

* src/Makefile.am (%protocol.c, %protocol.h): Force output to srcdir.

1b7bfa65e3 qemu: Use "migratable" XML definition when doing external checkpoints
In the original implementation of external checkpoints I've mistakenly
used the live definition to be stored in the save image. The normal
approach is to use the "migratable" definition. This was discovered when
commit 07966f6a8b changed the behavior to
use a converted XML from the user to do the compatibility check to fix
problem when using the regular machine saving.

As the previous patch added a compatibility layer, we can now change the
type of the XML in the image.

59898a88ce qemu: Fix checking of ABI stability when restoring external checkpoints
External checkpoints have a bug in the implementation where they use the
normal definition instead of the "migratable" one. This causes errors
when the snapshot is being reverted using the workaround method via
qemuDomainRestoreFlags() with a custom XML. This issue was introduced
when commit 07966f6a8b changed the code to
compare "migratable" XMLs from the user as we should have used
migratable in the image too.

This patch adds a compatibility layer, so that fixing the snapshot code
won't make existing snapshots fail to load.
