I've noticed that these APIs are missing @flags argument. Even
though we don't have a use for them, it's our policy that every
new API must have @flags.

They recently were extracted to a separate function. They don't belong
together though. Since -numa formatting is pretty compact, move it to
the main function and rename qemuBuildNumaCommandLine to
qemuBuildMemoryDeviceCommandLine.

When starting up a VM libvirtd asks numad to place the VM in case of
automatic nodeset. The nodeset would not be passed to the memory device
formatter and the user would get an error.

Commit 7068b56c introduced several hyperv features.  Not all hyperv
features are supported by old enough kernels and we shouldn't allow to
start a guest if kernel doesn't support any of the hyperv feature.

There is one exception, for backward compatibility we cannot error out
if one of the RELAXED, VAPIC or SPINLOCKS isn't supported, for the same
reason we ignore invtsc, to not break restoring saved domains with older
libvirt.

This check is there to allow restore saved domain with older libvirt
where we included invtsc by default for host-passthrough model.  Don't
skip the whole function, but only the part that checks for invtsc.

If the cpu cgroup is not found when validating an host for
LXC support, virt-host-validate will suggest to enable the
CONFIG_CGROUP_SCHED kconfig option.

The appropriate option is really CONFIG_CGROUP_CPU. The
QEMU checks already get that right, so no changes needed.

Remove disabling domain death events from libxlDomainStart error
path. The domain death event is already disabled in libxlDomainCleanup.
Signed-off-by: NJim Fehlig <jfehlig@suse.com>

libxlDomainStart allocates and reserves resources that were not
being released in error paths. libxlDomainCleanup already handles
the job of releasing resources, and libxlDomainStart should call
it when encountering a failure.

Change the error handling logic to call libxlDomainCleanup on
failure. This includes acquiring the lease sooner and allowing
it to be released in libxlDomainCleanup on failure, similar to
the way other resources are reclaimed. With the lease now
released in libxlDomainCleanup, the release_dom label can be
renamed to cleanup_dom to better reflect its changed semantics.

Create a bitmap of iothreads that have scheduler info set so that the
transformation algorithm does not have to iterate the empty bitmap many
times. By reusing self-expanding bitmaps the bitmap size does not need
to be pre-calculated.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1264008

In some cases it's impractical to use the regular APIs as the bitmap
size needs to be pre-declared. These new APIs allow to use bitmaps that
self expand.

The new code adds a property to the bitmap to track the allocation of
memory so that VIR_RESIZE_N can be used.

 * Sync stubbed functions with prototypes
 * Add missing ATTRIBUTE_UNUSED where needed

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1288000

Historically we've used 'unsigned long' and allowed wrapping of negative
numbers for bandwidth values. Add a helper that will simplify adding
support for scaled integers and support for byte granularity while
keeping the compatibility with the older approach.

Fix control flow and spacing issues.

It was too similar to the non-scaled alternative.

before:
error: Numeric value 'abc' for <size> option is malformed or out of range
after:
error: Scaled numeric value 'abc' for <size> option is malformed or out of range

Move the function to qemu_domain.c and export them for further use.

Now that there are only two elements in the enum, let's change it to a
bool and rename the function similarly to the one added in previous
commit.

Introduce qemuDomainDiskChainElementRevoke that revokes the access
rather than having a flag to do so.

The function has terrible semantics. Split it into two functions.

qemu won't ever add those functions directly to QMP. They will be
replaced with 'blockdev-add' and 'blockdev-del' eventually. At this time
there's no need to keep the stubs around.

Additionally the drive_del stub in JSON contained dead code in the
attempt to report errors. (VIR_ERR_OPERATION_UNSUPPORTED was never
reported). Since the text impl does have the same message it is reported
anyways.

Functions no longer required for attaching SCSI disks since
QEMU_CAPS_DEVICE is expected.

We've started to assume support for QEMU_CAPS_DEVICE. Doing so in the
SCSI disk hotplug code allows us to drop a lot of ugly legacy code.
