Even if this doesn't have any practical use for actually creating
instances, it can be used for very fast burnin and testing just the
add/start/stop/remove functionality.

This has also revealed a bug in export/import related to diskless
instances, so it's educational value is proved.

Currently the fake hypervisor has hardcoded ‘/var/run’ as a base
directory for its store. This patch adds a constant RUN_DIR that is used
for both the fake hypervisor and for BDEV_CACHE_DIR.

The script (which is geared towards Debian) is actually not fully

In revision 459 I added a bug in the make dist rule in the sense that
the archive will include *all* of test/data directory, including the
.svn directory if it exists.

This patch fixes that problem and adds a distcheck hook that tests for
such errors in the future (files/directories matching the .svn and .git
patterns).

It also fixes a typo in the NEWS file.

Even though burnin was born just to do that test it now contains a lot more
things one might try, so it makes sense to make instance start/stop optional
too.

This creates a burnin that at the bare minimum tests instance create and
remove, if all the --no options are specified, but usually does a lot more.

Instances get exported to a remote node, then removed and imported back to
their original nodes. This should be an idempotent option from the instance
point of view, and help making sure ImportExport is kept up to date.

It will also help making burnin take a lot longer, which is nice to take a nap.
"...but I'm doing a cluster burnin...". Unfortunately this subfeature is a bit
jeopardized by the fact that the new code can be skipped with the
--no-importexport option, but nobody needs to know that, do they?

Some new paramenters of the CreateInstance opcode are optional (namely
kernel_path, initrd_path and hvm_boot_order) but their absence makes the code
crash. Fix this by initializing them to a default value if they're not present.

Mac is now a mandatory option for OpCreateInstance. Add it when we call this
opcode at import time too. This is a quick fix for the code, but probably more
work needs to be done to integrate mac addresses with the import/export

This patch modifes the ‘gnt-instance’ instance manpage with the new

This patch changes the hypervisor to use the new kernel and initrd
instance attributes. They kernel is handled as expected (use the custom

order to keep compatibility with previous behaviour:
  - if customized and not found, raise an error
  - if default and not found, do not use one
