Volume with save_on_stop=False and snap_on_start=False exists only when
VM is running and this is already handled under is_dirty() condition.
For non-running VMs, skip LVM resize step and only update internal size
attribute.
FixesQubesOS/qubes-issues#5645
When volume is resized, underlying LVM is adjusted if exists. For
persistent volumes it is enough, as generally the driver prefers
underlying LVM size than internal attribute. But volatile volume is
removed at vm shutdown, so that value is lost.
Fix it by updating Volume.size attribute too, to be updated in qubes.xml
later too.

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.)

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

xl devd doesn't use startup notify, so when the service is started

little sleep for that.

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.
The default (= text) mode for a loop device which contains a VM image
looked weird, even though it didn't make a difference here because the
dev_io object was never actually read from.
When setting global clockvm property, 'clocksync' service is
automatically added to the new value and then removed from the old one.
But if the new value is the same as the old one, the service gets
removed from the just set new value.
Check for this case explicitly.

'extra' tests run is getting ridiculously long. Allow splitting it into
several jobs. Since this appears as just one class from the test loader
perspective, implement it as environment variables:
- QUBES_TEST_EXTRA_INCLUDE - load just selected tests
- QUBES_TEST_EXTRA_EXCLUDE - skip selected tests (to select "the rest"
tests)

Only first 4 disks can be emulated as IDE disks by QEMU. Specifically,
CDROM must be one of those first 4 disks, otherwise it will be
ignored. This is especially important if one wants to boot the VM from
that CDROM.
Since xvdd normally is a kernel-related volume (boot image, modules) it
makes perfect sense to re-use it for CDROM. It is either set for kernel
volume (in which case, VM should boot from it and not the CDROM), or
(possibly bootable) CDROM.
This needs to be done in two places:
- BlockExtension for dynamic attach
- libvirt xen.xml - for before-boot attach
In theory the latter would be enough, but it would be quite confusing
that device will get different options depending on when it's attached
(in addition to whether the kernel is set - introduced here).
This all also means, xvdd not always is a "system disk". Adjust listing
connected disks accordingly.
- allow TestQubesDB to be populated with initial data
- support list() method
- allow to register pre-created VM instance (useful for AdminVM, which
don't accept setting qid)
Pool.volumes property is implemented in a base class, individual drivers
should provide list_volumes() method as a backend for that property.
Fix this in a LinuxKernel pool.
Similar to admin.vm.volume.List. There are still other
admin.pool.volume.* methods missing, but lets start with just this one.
Those with both pool name and volume id arguments may need some more
thoughts.
Don't realy on a volume configuration only, it's easy to miss updating
it. Specifically, import_volume() function didn't updated the size based
on the source volume.
The size that the actual VM sees is based on the
file size, and so is the filesystem inside. Outdated size property can
lead to a data loss if the user perform an action based on a incorrect
assumption - like extending size, which actually will shrink the volume.
FixesQubesOS/qubes-issues#4821
Handle this case specifically, as way too many users ignore the message
during installation and complain it doesn't work later.

admin.pool.UsageDetails reports the usage data, unlike
admin.pool.Info, which should report the config/unchangeable data.
At the moment admin.Pool.Info still reports usage, to maintain
compatibility, but once all relevant tools are updated,
it should just return configuration data.
Added usage_details method to Pool class
(returns a dictionary with detailed information
on pool usage) and LVM implementation that returns
metadata info.
