If unmount is going to fail, let it do so explicitly, instead of hiding
the failure now, and observing it later at rmdir.
And if it fails, lets report what process is using that mount point.
Xenial environment has much newer GTK/Glib. For those test to run, few
more changes are needed:
- relevant GTK packages installed
- X server running (otherwise GTK terminate the process on module
import...)
- enable system side packages in virtualenv set by travis
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.

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.
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.

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.

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.
First install test-pkg-1.0, then add test-pkg-1.1 to repo and check if
updates-available flag is set. Then install updates and check if the
flag is cleared.

The new property is meant for management stack (Salt) to set which DVM
template should be used to maintain given VM. Since the DispVM based on
it will be given ultimate control over target VM (qubes.VMShell
service), it should be trusted. The one pointed to by default_dispvm
not necessary is one.
The property defaults to the value from the template (if any), and then
to a global management_dispvm property. By default it is set to None.

Use maxmem=0 for disabling dynamic memory balance, instead of cryptic
service.meminfo-writer feature. Under the hood, meminfo-writer service
is also set based on maxmem property (directly in qubesdb, not
vm.features dict).
Having this as a property (not "feature"), allow to have sensible
handling of default value. Specifically, disable it automatically if
otherwise it would crash a VM. This is the case for:
- domain with PCI devices (PoD is not supported by Xen then)
- domain without balloon driver and/or meminfo-writer service
The check for the latter is heuristic (assume presence of 'qrexec' also
can indicate balloon driver support), but it is true for currently
supported systems.
This also allows more reliable control of libvirt config: do not set
memory != maxmem, unless qmemman is enabled.
memory != maxmem only makes sense if qmemman for given domain is
enabled. Besides wasting some domain resources for extra page tables
etc, for HVM domains this is harmful, because maxmem-memory difference
is made of Popupate-on-Demand pool, which - when depleted - will kill
the domain. This means domain without balloon driver will die as soon
as will try to use more than initial memory - but without balloon driver
it sees maxmem memory and doesn't know about the lower limit.

It makes a lot of sense to call long-running operations in that event
handler, including calling back into the VM. Allow that by using
fire_event_async, not just fire_event.
Also, document the event.
Commit 15cf593bc5 "tests/lvm: fix checking
lvm pool existence" attempted to fix handling '-' in pool name by using
/dev/VG/LV symlink. But those are not created for thin pools. Change
back to /dev/mapper, but include '-' mangling.

Try to collect more details about why the test failed. This will help
only if qvm-open-in-dvm exist early. On the other hand, if it hang, or
remote side fails to find the right editor (which results in GUI error
message), this change will not provide any more details.
First boot of whonix-ws based VM take extended period of time, because
a lot of files needs to be copied to private volume. This takes even
more time, when verbose logging through console is enabled. Extend the
timeout for that.
