There's no sense in advertising cpuselection capability when host CPU
is not properly detected and advertised in host capabilities.

When qemu libvirt driver doesn't support guest CPU selection with given
qemu binary, guests requiring specific CPU should fail to start instead
of being silently supplied with a default CPU.

* src/qemu/qemu_driver.c (qemuDomainSnapshotLoad): Remove dead store
into "snap", as well as its declaration.

git grep found 12 of the former but 100 of the latter in src/.

* src/remote/remote_driver.c (initialise_gnutls): Rename...
(initialize_gnutls): ...to this.
(doRemoteOpen): Adjust caller.
* src/xen/xen_driver.c (xenUnifiedOpen): Adjust output string.
* src/util/network.c: Adjust comments.
Suggested by Matthias Bolte.

* src/conf/domain_event.c (virDomainEventGraphicsNewFromDom):
Return NULL when handling out-of-memory error, rather than
falling through with ev=NULL and then assigning to ev->member.
(virDomainEventGraphicsNewFromObj): Likewise.

The attached patch fixes a problem due to the mac match in iptables only
supporting --mac-source and no --mac-destination, thus it not being
symmetric. Therefore a rule like this one

<rule action='drop' direction='out'>
  <all match='no' srcmacaddr='$MAC'/>
</rule>

should only have the MAC match on traffic leaving the VM and not test
for the same source MAC address on traffic that the VM receives.

* src/qemu/qemu_driver.c (qemudStartVMDaemon): Initialize "logfile"
to ensure that we don't use it uninitialized -- thus closing an
arbitrary file descriptor -- in the cleanup block.

* tests/virt-aa-helper-test: test augmented with hostdev and sdl display
  checks

* examples/apparmor/libvirt-qemu examples/apparmor/usr.sbin.libvirtd
  examples/apparmor/usr.lib.libvirt.virt-aa-helper: Update the examples

* src/security/virt-aa-helper.c: add support for SDL devices and 3
  code cleanups

* src/security/virt-aa-helper.c: adjust virt-aa-helper to handle pci
  devices. Update valid_path() to have an override array to check against,
  and add "/sys/devices/pci" to it. Then rename file_iterate_cb() to
  file_iterate_hostdev_cb() and create file_iterate_pci_cb() based on it

adjust virt-aa-helper to handle backing store
* src/security/virt-aa-helper.c: look for backing store metadata
  for disk definitions.

To avoid an error when hitting the <seclabel...> definition
* src/security/virt-aa-helper.c: add VIR_DOMAIN_XML_INACTIVE flag
  to virDomainDefParseString

Don't exit with error if the user unloaded the profile outside of
 libvirt
* src/security/virt-aa-helper.c: check the exit error from apparmor_parser
  before exiting with a failure

The calls to virExec() in security_apparmor.c when
invoking virt-aa-helper use VIR_EXEC_CLEAR_CAPS. When compiled without
libcap-ng, this is not a problem (it's effectively a no-op) but with
libcap-ng this causes MAC_ADMIN to be cleared. MAC_ADMIN is needed by
virt-aa-helper to manipulate apparmor profiles and without it VMs will
not start[1]. This patch calls virExec with the default VIR_EXEC_NONE
instead.
* src/security/security_apparmor.c: fallback to VIR_EXEC_NONE flags for
  virExec of virt_aa_helper

Tested by running 'git submodule foreach git pull origin master' and
'git add .gnulib', then seeing that 'make clean' skips autogen
although 'make' properly runs it.

* cfg.mk (_clean_requested): New check, to speed up 'make clean'
even if gnulib submodule is outdated.
Suggested by Daniel P. Berrange.

Fixing the regular expressions for variables where the first letter must be a $.

Also rename ReportError to macvtapError.

* src/util/virterror.c (virErrorMsg): Insert missing "break;"

Also define ESX_ERROR and ESX_VI_ERROR in a central place, instead of
defining them in each source file.

Add ESX_ERROR and ESX_VI_ERROR to the msg_gen_function list in cfg.mk.

Update po/POTFILES.in accordingly.

Add vboxError to the msg_gen_function list in cfg.mk.

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.

This patch fixes some compilation issues for the RHEL5 build. I am also removing the IPV6 constant where it appears in the wrong place.

This only affects builds without NUMA support.

Also remove unused enum values OPENVZ_WARN and OPENVZ_ERR.
