Ensure that there are no leftover image files for the volume, e.g. from
an unsuccessful removal of a previous incarnation of this vid, or from
an messily restored pool filesystem backup. We don't want to preserve
any stale data (revisions) or metadata (size) in the new incarnation.
The size config parameter might be a string coming from XML.
The Volume base class handles the conversion to integer already.
FixesQubesOS/qubes-issues#5219.
This should allow importing a volume and changing the size at the
same time, without performing the resize operation on original
volume first.
The internal API has been renamed to internal.vm.volume.ImportBegin
to avoid confusion, and for symmetry with ImportEnd.
See QubesOS/qubes-issues#5239.

storage/reflink: fix comment
storage/reflink: bail out early on most FICLONE errnos
storage/reflink: pool.setup_check -> pool._setup_check
Don't fall back on 'cp' if the FICLONE ioctl gives an errno that's not
plausibly reflink specific, because in such a case any fallback could
theoretically mask real but intermittent system/storage errors.
Looking through ioctl_ficlone(2) and the kernel source, it should be
sufficient to do the fallback only on EBADF/EINVAL/EOPNOTSUPP/EXDEV.
(EISDIR/ETXTBSY don't apply to this storage driver, which will never
legitimately attempt to reflink a directory or an active - in the
storage domain - swap file.)
* origin/pr/303:
Update tests after adding /connected-ips
Also reload /connected-ips on firewall change / domain spawn
Also store /connected-ips6 for machines that have IPv6 addresses
Don't try to write to qubesdb of an offline VM
Maintain a list of connected machine IPs in qubesdb
Extension objects are singletons and normally do not require any special
cleanup. But in case of tests, we try to remove all the qubes objects
between tests and the cache in usb extension makes it hard.
Add a 'qubes-close' event that extensions can handle to remove extra
references stored in extension objects themselves.
Due to strangeness of KeyError (it overrrides __str__ method) in some
cases exceptions received superflous quotation marks when inheriting
from it.

* origin/pr/298:
tests/network: let xl devd bring the interfaces up
tests/network: improve error reporting
api/admin: implement *.property.GetAll methods
Avoid resetting clocksync service of just enabled clockvm
doc/tests: extend qubes-specific quirks in tests
tests: add include and exclude lists for extra tests loader
xl devd doesn't use startup notify, so when the service is started
(according to systemd) it may still be initializing interfaces. Add a
little sleep for that.
Allow getting all the VM properties with one call. This greatly improve
performance of an applications retrieving many/all of them (qvm-ls,
qubes manager etc)

One alternative would look like
import ctypes
sizeof_int = ctypes.sizeof(ctypes.c_int)
FICLONE = (1073741824 % 256**sizeof_int) | 37897 | (sizeof_int << 16)
but, even if the above really(?) is a 100% correct Python port of
$ echo FICLONE | cpp -include linux/fs.h | tail -n 1
it still seems more likely that the ctypes package is somehow buggy
somewhere than for Qubes storage to run on an exotic architecture with
non 32 bit ints (in the foreseeable future).
So just document the baked in assumption.
