Fix qubes-core.service ordering
The previous version did not ensure that the stopped/shutdown event was
handled before a new VM start. This can easily lead to problems like in
QubesOS/qubes-issues#3164.
This improved version now ensures that the stopped/shutdown events are
handled before a new VM start.
Additionally this version should be more robust against unreliable
events from libvirt. It handles missing, duplicated and delayed stopped
events.
Instead of one 'domain-shutdown' event there are now 'domain-stopped'
and 'domain-shutdown'. The later is generated after the former. This way
it's easy to run code after the VM is shutdown including the stop of
it's storage.
If there was some netvm set, unset it first (same as with ordinary set).
Otherwise it will try to attach new netvm without detaching the old one
first.
vm.create_qdb_entries can be called multiple times - for example when
changing VM IP. Move starting qdb watcher to start(). And just in case,
cleanup old watcher (if still exists) before starting new one.
This fixes one FD leak.
Catch exception there and log it. Otherwise asyncio complains about not
retrieved exception. There is no one else to handle this exception,
because shutdown event is triggered from libvirt, not any Admin API.
Allow to get domain class as a property, not using admin.vm.List call.
This makes it unnecessary to call admin.vm.List on the client side to
construct wrapper object.
There is intentionally no default template in terms of qubes.property
definition, to not cause problems when switching global default_template
property - like breaking some VMs, or forcing the user to shutdown all
of them for this. But this also means it shouldn't be allowed to reset
template to "default" value, because it will result in a VM without
template at all.
FixesQubesOS/qubes-issues#3115
If VM startup failed before starting anything (even in paused state),
there will be no further event, not even domain-shutdown. This makes it
hard for event-listening applications (like domains tray) to account
domain state. Fix this by emiting domain-start-failed event in every
case of failed startup after emiting domain-pre-start.

'dispvm_allowed' name was confusing, because it suggested being able to
spawn new DispVMs, not being a template for DispVM.
FixesQubesOS/qubes-issues#3047
Clone properties from DispVM template after setting base properties
(qid, name, uuid). This means we can use standard clone_properties()
function. Otherwise various setters may fail - for example
netvm setter require uuid property initialized (for VM lookup in VM
collection).
Also, make dispvm_allowed check more robust - include direct creation of
DispVM, and also check just before VM startup (if property was changed
in the meantime).
FixesQubesOS/qubes-issues#3057
This is useful to select default DispVM template for VMs started
directly by the user. This makes sense as long as AdminVM == GUIVM.
QubesOS/qubes-issues#2974
Add auto_cleanup property, which remove DispVM after its shutdown
- this is to unify DispVM handling - less places needing special
handling after DispVM shutdown.
New DispVM inherit all settings from respective AppVM. Move this from
classmethod `DispVM.from_appvm()`, to DispVM constructor. This unify
creating new DispVM with any other VM class.
Notable exception are attached devices - because only one running VM can
have a device attached, this would prevent second DispVM started from
the same AppVM. If one need DispVM with some device attached, one can
create DispVM with auto_cleanup=False. Such DispVM will still not have
persistent storage (as any other DispVM).
Tests included.

storage: move volume_config['source'] filling to one place
app: do not create 'default' storage pool
app: add missing setters for default_pool* global properties
Don't set 'source' volume in various places (each VM class constructor
etc), do it as part of volume initialization. And when it needs to be
re-calculated, call storage.init_volume again.
This code was duplicated, and as usual in such a case, those copies
were different - one have set 'size', the other one not.
QubesOS/qubes-issues#2256
Since we have app.default_pool* properties, create appropriately named
pool and let those properties choose the right pool. This also means we
don't need to specify pool name in default volume config anymore
