If kernel package ships default-kernelopts-common.txt file, use that
instead of hardcoded Linux-specific options.
For Linux kernel it may include xen_scrub_pages=0 option, but only if
initrd shipped with this kernel re-enable this option later.

Return meaningful value for kernels_dir if VM has no 'kernel' volume.
Right now it's mostly useful for tests, but could be also used for new
VM classes which doesn't have modules.img, but still use dom0-provided
kernel.
First of all, do not try to call those services in VMs not having qrexec
installed - for example Windows VMs without qubes tools.
Then, even if service call fails for any other reason, only log it but
do not prevent other services from being called. A single uncooperative
VM should generally be able only to hurt itself, not break other VMs
during suspend.

libxenvchan currently can't handle loopback connections. Since error
reporting on vchan connection setup is far from perfect, try to avoid
making such connections at all.

Since we have more reliable domain-shutdown event delivery (it si
guaranteed to be delivered before subsequent domain start, even if
libvirt fails to report it), it's better to move detach_network call to
domain-shutdown handler. This way, frontend domain will see immediately
that the backend is gone. Technically it already know that, but at least
Linux do not propagate that anywhere, keeping the interface up,
seemingly operational, leading to various timeouts.
Additionally, by avoiding attach_network call _just_ after
detach_network call, it avoids various race conditions (like calling
cleanup scripts after new device got already connected).
While libvirt itself still doesn't cleanup devices when the backend
domain is gone, this will emulate it within qubesd.

Pool setup/destroy may be a time consuming operation, allow them to be
asynchronous. Fortunately add_pool and remove_pool are used only through
Admin API, so the change does not require modification of other
components.
Boolean properties require specific setter to properly handle literal
"True" and "False" values. Previously it required all bool properties to
include 'setter=qubes.property.bool' in addition to 'type=bool'.
This fixes loading some boolean properties from qubes.xml. Specifically
at least include_in_backups on DispVM class lacked setter, which
resulted in property being reset to True automatically on qubesd
restart.

If default-kernelopts-pci.txt is present, it will override default
built-in kernelopts for the VMs with PCI device assigned.
Similarly if default-kernelopts-nopci.txt is present, it will override
default kernelopts for VMs without PCI devices.
For template-based VMs, kernelopts of the template takes precedence over
default-kernelopts-nopci.txt but not default-kernelopts-pci.txt.

The jinja templates are located in either /etc/qubes/templates or
/usr/share/qubes/templates. /usr/share/templates is not used and
/usr/share/qubes/template/ does not exist.
Fix the paths that are documented in
https://dev.qubes-os.org/projects/core-admin/en/latest/libvirt.html
If a specific DVM template is used for given DispVM, make new DispVMs
called from it use the same DVM template (unless explicitly overridden).
This prevent various isolation bypass cases, like using a chain of
DispVMs to access network.
Look for the first updateable template up in the template chain, instead
of going just one level up. Especially this applies to
DispVM -> AppVM -> TemplateVM case.
If DispVM reports available updates, 'updates-available'
flag should be set on relevant TemplateVM, not AppVM (*-dvm).
Include test for the new case.

Instead of checking if domain is still running/paused, try to kill it
anyway and ignore appropriate exception. Otherwise domain could die
before the check and killing.
some-vm-root is a valid VM name, and in that case it's volume can be
named some-vm-root-private. Do not let it confuse revision listing,
check for unexpected '-' in volume revision number.
The proper solution would be to use different separator, that is not
allowed in VM names. But that would require migration code that is
undesired in the middle of stable release life cycle.

* tests-20181223:
tests: drop expectedFailure from qubes_desktop_run test
tests: grub in HVM qubes
tests: update dom0_update for new updates available flag
tests: regression test LVM listing code
tests/extra: wrap ProcessWrapper.wait() to be asyncio-aware
tests: adjust backupcompat for new maxmem handling
This commit resolves a bug which causes strings such as "350MiB" to be
rejected by parse_size, due to the fact that parse_size changes the case
of letters in the input string ("350MiB") to uppercase ("350MIB"), but
fails to do the same for the elements of the units conversion table.
The correction is simple: Apply the same case change to the units
table elements before comparison.
The user of ExtraTestCase don't need to know anything about asyncio.
vm.run().wait() normally is a coroutine, but provide a wrapper that
handle asyncio.
This fixes FD leak in input proxy tests.
Since 4dc86310 "Use maxmem=0 to disable qmemman, add more automation to
it" meminfo-writer service is not accessible directly. maxmem property
is used to encode memory management instead.
- Two new methods: .features.check_with_adminvm() and
.check_with_template_and_adminvm(). Common code refactored.
- Two new AdminAPI calls to take advantage of the methods:
- admin.vm.feature.CheckWithAdminVM
- admin.vm.feature.CheckWithTemplateAndAdminVM
- Features manager moved to separate module in anticipation of features
on app object in R5.0. The attribute Features.vm renamed to
Features.subject.
- Documentation, tests.
