* src/conf/domain_conf.h: Add new member "target" to struct
_virDomainDeviceDriveAddress.
* src/conf/domain_conf.c: Parse and format "target"
* Lots of tests (.xml) in tests/domainsnapshotxml2xmlout,
tests/qemuxml2argvdata, tests/qemuxml2xmloutdata, and
tests/vmx2xmldata/ are modified for newly introduced
attribute "target" for address of "drive" type.
Some tools, such as virt-manager, prefers having the default USB
controller explicit in the XML document. This patch makes sure there
is one. With this patch, it is now possible to switch from USB1 to
USB2 from the release 0.9.1 of virt-manager.
Fix tests to pass with this change.
This adds per-device weights to <blkiotune>. Note that the
cgroups implementation only supports weights per block device,
and not per-file within the device; hence this option must be
global to the domain definition rather than tied to individual
<devices>/<disk> entries:
<domain ...>
<blkiotune>
<device>
<path>/path/to/block</path>
<weight>1000</weight>
</device>
</blkiotune>
..
This patch also adds a parameter --device-weights to virsh command
blkiotune for setting/getting blkiotune.weight_device for any
hypervisor that supports it. All <device> entries under
<blkiotune> are concatenated into a single string attribute under
virDomain{Get,Set}BlkioParameters, named "device_weight".
