The way that our file locking works is that we open() the file we
want to lock and then use fcntl(fd, F_SETLKW, ...) to lock it.
The problem is, we are doing all of these as root which doesn't
work if the file lives on root squashed NFS, because if it does
then the open() fails. The way to resolve this is to make this a
non fatal error and leave callers deal with this (i.e. disable
remembering) - implemented in the previous commit.

There is duplicated code between virt drivers that needs to
be moved to avoid code repetition. In the case of duplicated
code between lxc_cgroup.c and qemu_cgroup.c a common place
would be utils/vircgroup.c. The problem is that this would
introduce /conf related definitions that shouldn't be imported
to vircgroup.c, which is supposed to be a place for utilitary
cgroups functions only. And syntax-check would forbid it anyway
due to cross-directory includes being used.
An alternative would be to overload domain_conf.c, which already
contains all the definitions required. But that file is already
crowded with XML handling code and we wouldn't do any favors to
it by putting more utilitary, non-XML parsing/formatting code
there.
In [1], Cole suggested a 'domain_cgroup' file to host common code
between lxc_cgroup and qemu_cgroup, and Daniel suggested a
'src/hypervisor' dir to host these type of files. This patch
introduces src/hypervisor/domain_cgroup.c and, to get started,
introduces a new virDomainCgroupSetupBlkio() function to host shared
code between virLXCCgroupSetupBlkioTune() and qemuSetupBlkioCgroup().

During the hypervisor-agnostic validation of network devices, verify

there is any <virtualport>, that it doesn't have any type associated
with it.
This needs to be done both for the parse-time validation and for
runtime validation (after a port has been acquired from any associated
network), because an interface with type='network' could have an
actual type at runtime of "hostdev" or "direct", neither of which
support isolated='true' (yet). Likewise, if an interface is
type='network', then at runtime a <virtualport> with a type that

Similar to the way that the <vlan>, <bandwidth>, and <virtualport>
elements and the trustGuestRxFilters attribute in a <network> (or in
the appropriate <portgroup> element of a <network> can be applied to a
port when it is allocated for a domain's network interface, this patch
checks for a configured value of <port isolated="yes|no"/> in
either the domain <interface> or in the network, setting isolatedPort
in the <networkport> to the first one it finds (the setting from the
domain's <interface> is preferred). This, in turn, is passed back to
the domain when a port is allocated, so that the domain will use that
setting.
(One difference from <vlan>, <bandwidth>, <virtualport>, and
trustGuestRxFilters, is that all of those can be set in a <portgroup>
so that they can be applied only to a subset of interfaces connected
to the network. This didn't really make sense for the isolated setting
due to the way that it's implemented in Linux - the BR_ISOLATED flag
will prevent traffic from passing between two ports that both have
BR_ISOLATED set, but traffic can still go between those ports and
other ports that *don't* have BR_ISOLATED. (It would be nice if all
traffic from a BR_ISOLATED port could be blocked except traffic going
to/from a designated egress port or ports, but instead the entire
feature is implemented as a single flag. Because of this, it's really
only useful if all the ports on a network are isolated, so setting it

Not only was the original error code destroyed in the case of
encountering an error during recovery from a failed attach to the
bridge (and then *that* error was destroyed by logging a *second*
error about the failure to recover - virNetDevBridgeAddPort() already
logs an error, so the one about failing to recover was redundant), but
if the recovery was successful, the function would then return success
to the caller even though it had failed.
