Ensure we don't introduce any more lousy integer parsing in new

Note that we also need to enable sc_prohibit_atoi_atof (see cfg.mk

entails scrubbing I'm not ready to do at the moment.

https://bugzilla.redhat.com/show_bug.cgi?id=617711 reported that
even with my recent patched to allow <memory unit='G'>1</memory>,
people can still get away with trying <memory>1G</memory> and
silently get <memory unit='KiB'>1</memory> instead.  While
virt-xml-validate catches the error, our C parser did not.

DBus connection. The HAL device code further requires that
the DBus connection is integrated with the event loop and
provides such glue logic itself.

The forthcoming FirewallD integration also requires a
dbus connection with event loop integration. Thus we need
to pull the current event loop glue out of the HAL driver.

Thus we create src/util/virdbus.{c,h} files. This contains
just one method virDBusGetSystemBus() which obtains a handle
to the single shared system bus instance, with event glue
automagically setup.

Fix the support for trusted DHCP server in the ebtables code's
hard-coded function applying DHCP only filtering rules:
Rather than using a char * use the more flexible
virNWFilterVarValuePtr that contains the trusted DHCP server(s)

Since all callers so far provided NULL as parameter, no changes
are necessary in any other code.

For threading support, add atomic add and sub operations working on

Implement function to remove all entries of a hash table.

Currently upon a migration a callback is created when a 802.1qbg link
is set to PREASSOCIATE, this should not happen because this is a no-op
on most switches, and does not lead to an ASSOCIATE state.  This patch
only creates callbacks when CREATE or RESTORE is requested.  Migration
and libvirtd restart scenarios are already handled elsewhere.

I'm tired of shell-scripting to wait for completion of a block pull,
when virsh can be taught to do the same.  I couldn't quite reuse
vshWatchJob, as this is not a case of a long-running command where
a second thread must be used to probe job status (at least, not unless
I make virsh start doing blocking waits for an event to fire), but it
served as inspiration for my simpler single-threaded loop.  There is
up to a half-second delay between sending SIGINT and the job being
aborted, but I didn't think it worth the complexity of a second thread
and use of poll() just to minimize that delay.

* tools/virsh.c (cmdBlockPull): Add new options to wait for
completion.
(blockJobImpl): Add argument.
(cmdBlockJob): Adjust caller.
* tools/virsh.pod (blockjob): Document new mode.

Most of our errors complaining about an inability to support a

* tools/virsh.c: Fix some spacing issues, {} usage, long lines,

Passing a NULL pointer to IMachine::delete virtualbox API
causes VBoxSVC to raise an assertion. This patch passes
an empty array instead.

<filesystemtgt> is redundant, as every group uses it; <address>
shouldn't be in <filesystemtgt> in case of the meaning could be
"filesystemtarget"; The elements <address>, <alias>, <target>,
... should be interleaved.

So that a domain xml which doesn't have "placement" specified, but
"cpuset" is specified, could be parsed. And in this case, the
"placement" mode will be set as "static".

Since now we have fixed domain UUID for test driver, defining
a domain with different name but same UUID doesn't work any
more. This patch delete the UUID from the dumped XML so that
it could be generated.

The objects (domain, pool, network, etc) for testing are defined/
started each time when opening a connect to test driver, and thus
the UUID for the objects will be generated each time, with different
values. e.g.

% for i in {1..3}; do ./tools/virsh --connect \
  test:///default dumpxml test | grep uuid; done
  <uuid>a1b6ee1f-97de-f0ee-617a-0cdb74947df5</uuid>
  <uuid>ee68d7d2-3eb9-593e-2769-797ce1f4c4aa</uuid>
  <uuid>fecb1d3a-918a-8412-e534-76192cf32b18</uuid>

It's the potential bug which can cause operations like below to fail:

$ virsh -c test:///default dumpxml test > test.xml

[ Some modificatons, though it's not supported, but it should work ]

$ virsh -c test:///default define test.xml

This patch set fixed UUID for objects which support it. (domain,
pool, network).

A "ide-drive" device can be either a hard disk or a CD-ROM,
if there is ",media=cdrom" specified for the backend, it's
a CD-ROM, otherwise it's a hard disk.

Upstream qemu splitted "ide-drive" into "ide-hd" and "ide-cd"
since commit 1f56e32, and ",media=cdrom" is not required for
ide-cd anymore. "ide-drive" is still supported for backwards
compatibility, but no doubt we should go foward.

A "scsi-disk" device can be either a hard disk or a CD-ROM,
if there is ",media=cdrom" specified for the backend, it's
a CD-ROM, otherwise it's a hard disk.

But upstream qemu splitted "scsi-disk" into "scsi-hd" and
"scsi-cd" since commit b443ae, and ",media=cdrom" is not
required for scsi-cd anymore. "scsi-disk" is still supported
for backwards compatibility, but no doubt we should go
foward.

If console[0] is an alias for serial[0], do not enforce the former to
have a PTY source type. This breaks serial consoles on stdio and makes
no sense.

When using the xm/xend stack to manage instances there is a bug
that causes the emulated interfaces to be unusable when the vif
config contains type=ioemu.

The current code already has a special quirk to not use this
keyword if no specific model is given for the emulated NIC
(defaulting to rtl8139).
Essentially it works because regardless of the type argument,i
the Xen stack always creates emulated and paravirt interfaces and
lets the guest decide which one to use. So neither xl nor xm stack
actually require the type keyword for emulated NICs.

It should be 0.9.12 instead of 0.9.11

'omitted' was mispelt 'commited' twice. One of the sentences with
the typo was also missing an 'is' ('each VCPU *is* pinned to all...')
which I added in this commit while I was at it.

Currently, we have 3 boolean arguments we have to pass
to qemuProcessStart(). As libvirt grows it is harder and harder
to remember them and their position. Therefore we should
switch to flags instead.

It's vznet.conf not vznetctl.conf, see e.g.:

http://git.openvz.org/?p=vzctl;a=blob;f=bin/vznetcfg.in;h=e91f5c4a0744c1ea149e1b8c241b666052e10b12;hb=HEAD

lvcreate want's the parent pool's name, not the pool path
lvchange and lvremove want lv specified as $vgname/$lvname

This largely worked before because these commands strip off a
starting /dev. But https://bugzilla.redhat.com/show_bug.cgi?id=714986
is from a user using a 'nested VG' that was having problems.

I couldn't find any info on nested LVM and the reporter never responded,
but I reproduced with XML that specified a valid source name, and
set target path to a symlink.

As explained in previous patch, numad will balance the affinity
dynamically, so reflecting the cpuset from numad at the first
time doesn't make much case, and may just could cause confusion.

Instead of returning a CPUs list, numad returns NUMA node
list instead, this patch is to convert the node list to
cpumap before affinity setting. Otherwise, the domain
processes will be pinned only to CPU[$numa_cell_num],
which will cause significiant performance losses.

Also because numad will balance the affinity dynamically,
reflecting the cpuset from numad back doesn't make much
sense then, and it may just could produce confusion for
the users. Thus the better way is not to reflect it back
to XML. And in this case, it's better to ignore the cpuset
when parsing XML.

The codes to update the cpuset is removed in this patch
incidentally, and there will be a follow up patch to ignore
the manually specified "cpuset" if "placement" is "auto",
and document will be updated too.

since this isn't available on older kernels such as Debian Squeeze's
2.6.32. This make --with-macvtap=check work as expected.

The linux-2.6.32 kernel header does not yet define IFLA_VF_MAX and others,
which breaks compiling a new libvirt on old systems like Debian Squeeze.

(I also have to add --without-macvtap --disable-werror --without-virtualport to
 ./configure to get it to compile.)
