365d1f5d56 diskbackend: Set relative path for media change
Via the virt-manager UI we aren't converting relative path to
absolute path, even though we do it internally when needed.

We were benefiting from this in the test suite in some ways, so we
need to adjust tests to strip out the dev dir on XML comparison

9e133de21a diskbackend: Restrict format->driver_type even more
We should only be returning a driver_type value for volumes that
report support_format(), meaning they support file type formats like
qcow2. Any other reported format should be ignored

Dropping the check for 'unknown' value changes one test case a bit,
but it hardcodes raw which is what libvirt gives us anyways, so it's
okay

2676640979 Disk pool volumes should be always attached as "raw" disks
Usually, when storage volume is attached as a disk and disk xml is filled with
default values, the "<driver type=...>" value is copied from volume's
"<format type=...>".  This makes sense for volumes of storage pool of type
"dir", where format types include "raw, qcow2...".

However, the same approach cannot be used for the storage pool of type "disk".
In that case, format types include "none, linux, fat16, fat32...". Such formats
cannot be used for disk's "<driver type=...>".

Therefore, when generating disk XML for volume of storage pool type "disk",
driver type should always be "raw".

5a7698c799 Fix selection of network volumes
When creating a new VM and selecting a volume from a network-based
storage pool such as rbd, the volume is not recognized as network-based
and is treated as a volume from a directory storage pool.

This patch adds a method to check if the volume's path points to a
network-based volume, then uses the method to avoid actions like
setting unix file permissions on the volume, which doesn't make
sense for a network-based volume.

6e6f59e7ab diskbackend: get a proper size of existing block device while cloning
We cannot use os.statvfs() if the clone disk is a block device because
it gets stats about filesystem which in this case is "devtmpfs" mounted
as "/dev".

As a workaround we can seek to the end of the block device to get
the actual size.
