This patch adds a relaxng nwfilter schema along with a test that
verifies all the test output XML against the schema. The input XMLs
contain a lot of intentional out-of-range values that make them fail the
schema verification, so I am not verifying against those.
With Eric Blake's suggestions applied.
The following rule for direction 'in'
<rule direction='in' action='drop'>
<mac srcmacaddr='1:2:3:4:5:6'/>
</rule>
drops all traffic from the given mac address.
The following rule for direction 'out'
<rule direction='out' action='drop'>
<mac dstmacaddr='1:2:3:4:5:6'/>
</rule>
drops all traffic to the given mac address.
The following rule in direction 'inout'
<rule direction='inout' action='drop'>
<mac srcmacaddr='1:2:3:4:5:6'/>
</rule>
now drops all traffic from and to the given MAC address.
So far it would have dropped traffic from the given MAC address
and outgoing traffic with the given source MAC address, which is not useful
since the packets will always have the VM's MAC address as source
MAC address. The attached patch fixes this.
This is the last bug I currently know of and want to fix.
Document several missing commands. There's more work that could be
done, but incremental improvements is better than no patch at all.
* tools/virsh.pod (autostart, connect): Improve grammar.
(create): Improve example.
(domjobabort, domjobinfo, domxml-from-native, domxml-to-native):
Document.
(storage pool commands): New section.
When hitting failures in virsh, a common idiom is
to jump to a cleanup label, free some resources, and
then return a FALSE error code to vshCommandRun.
In theory, vshCommandRun is then supposed to print
out the last error. The problem is that many of
the cleanup paths have library calls to free resources,
and all of those library calls clear out the last error.
This is leading to situations where no error is being
reported at all.
This patch remedies the situation somewhat by
printing out the errors inside the command methods
themselves when we know it will go through a cleanup
path that will lose the error.

When starting up qemu VNC autoport guests, we were
only looking through ports 5900 to 6000, meaning we
were limited to 100 total clients. Increase that
limit to 65535 (the last available port), so we can
have up to 59635 VNC autoport guests.

While playing around with def/newDef with the qemu code,
I noticed that newDef was *always* getting set to a value,
even when I didn't redefine the domain. I think the problem
is the virDomainLoadConfig is always doing virDomainAssignDef
regardless of whether the domain already exists in the hashtable.
In turn, virDomainAssignDef is assigning the definition (which
is actually a duplicate) to newDef. Fix this so that newDef stays
NULL until we actually have a new def.

values. Rather use the strspn() function. Along with this cleanup the
initialization function for the code that used the regular expression
can also be removed.
The images are saved in /var/lib/libvirt/qemu/save/
and named $domainname.save . The directory is created appropriately
at daemon startup. When a domain is started while a saved image is
available, libvirt will try to load this saved image, and start the
domain as usual in case of failure. In any case the saved image is
discarded once the domain is created.
* src/qemu/qemu_conf.h: adds an extra save path to the driver config
* src/qemu/qemu_driver.c: implement the 3 new operations and handling
of the image directory
* src/remote/remote_protocol.x src/remote/remote_protocol.h
src/remote/remote_protocol.c src/remote/remote_driver.c: add the entry
points in the remote driver
* daemon/remote.c daemon/remote_dispatch_args.h
daemon/remote_dispatch_prototypes.h daemon/remote_dispatch_table.h:
and implement the daemon counterpart
virDomainManagedSave() is to be run on a running domain. Once the call
complete, as in virDomainSave() the domain is stopped upon completion,
but there is no restore counterpart as any order to start the domain
from the API would load the state from the managed file, similary if
the domain is autostarted when libvirtd starts.
Once a domain has restarted his managed save image is destroyed,
basically managed save image can only exist for a stopped domain,
for a running domain that would be by definition outdated data.
* include/libvirt/libvirt.h.in src/libvirt.c src/libvirt_public.syms:
adds the new entry points virDomainManagedSave(),
virDomainHasManagedSaveImage() and virDomainManagedSaveRemove()

make -s <-- expecting auto-bootstrap here, doesn't happen
Use git diff to expose whether the submodule has untracked changes,
which are typical on an incremental pull if .gnulib was updated but
the user did not manually run 'git submodule update'.
After this patch is applied, I encountered a new problem when
following the reproducing pattern. Basically, the change to .gnulib
between libvirt's commit 96e5a2d4 and this patch introduced a change
to sys_ioctl.in.h, but gnulib (intentionally) does not make the
replacement headers depend on Makefile changes. Therefore, I ended up
with the generated replacement header being broken:
gnulib/lib/sys/ioctl.h complained about a use of @. But that seems
like something that should be fixed upstream in gnulib's bootstrap
script (that is, when doing a gnulib update, all files created from
.in.h file should probably be deleted). Without the benefit of that
proposed gnulib fix, I worked around the problem by manually removing
the stale gnulib/lib/sys/ioctl.h.
* autogen.sh (t): Also run bootstrap if the gnulib submodule needs
to be updated.
* cfg.mk (_autogen): Likewise.
