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.

This code is unused now. Theoretically this is_outdated implementation
should be moved to FileVolume, but since we don't have VM reference
there, it isn't possible to read appropriate xenstore entry. As we're
phasing out file pool, simply ignore it for now.

Those functions are coroutines anyway, so allow event handlers to be
too.
Some of this (`domain-create-on-disk`, `domain-remove-from-disk`) will
be useful for appmenus handling.
Always define those properties, always include them in volume config.
Also simplify overriding pool based on volume type defined by those:
override pool unless snap_on_start=True.

We've decided to make VM name immutable. This is especially important
for Admin API, where some parts (especially policy) are sticked to the
VM name.
Now, to rename the VM, one need to clone it under new name (thanks to
LVM, this is very quick action), then remove the old one.

* qubesos/pr/111:
vm: drop 'internal' property
qmemman: make sure to release lock
qmemman: fix meminfo parsing for python 3
devices: drop 'data' and 'frontend_domain' fields, rename 'devclass' to 'bus'
* qubesos/pr/110:
storage: use direct object references, not only identifiers
vm: fix volume_config
storage/lvm: prefix VM LVM volumes with 'vm-'
storage: fix VM rename
Reference objects, not their IDs - this way when object is modified, it
is visible everywhere where it is used. Main changes:
- volume.pool - Pool object
- volume.source - Volume object
Since volume have Pool object reference now, move volume related
functions into Volume class (from Pool class). This avoids horrible
`storage.get_pool(volume).something(volume)` construct.
One issue here is since volume.source reference a Volume object from a
different VM - VM's template, now VM load order is important. Since we
don't have control over it, initialize vm.storage when needed - possibly
while initializing storage of different VM. Since we don't have cycles
in AppVM-TemplateVM dependencies, it is safe.
Also, since this commit, volume.source (if defined) always points at
volume of the same name from VM's template. Using volumes with something
else as a source is no longer supported.
QubesOS/qubes-issues#2256
vm.kernel property have type 'str'. Putting None there makes a lot of
troubles: it gets encoded as 'None' in qubes.xml and then loaded back as
'None' string, not None value. Also it isn't possible to assign None
value to str property throgh Admin API.
kernel='' is equally good to specify "no kernel from dom0".
QubesOS/qubes-issues#2622
While libvirt handle locking itself, there is also Qubes-specific
startup part. Especially starting qrexec-daemon and waiting until
qrexec-agent connect to it. When someone will attempt to start VM the
second time (or simply assume it's already running) - qrexec will not be
connected yet and the operation will fail. Solve the problem by wrapping
the whole vm.start() function with a lock, including a check if VM is
running and waiting for qrexec.
Also, do not throw exception if VM is already running.
This way, after a call to vm.start(), VM will be started with qrexec
connected - regardless of who really started it.
Note that, it will not solve the situation when someone check if VM is
running manually, like:
if not vm.is_running():
yield from vm.start()
Such code should be changed to simply:
yield from vm.start()

And place them in /qubes-service/ QubesDB directory. This allows
extensions to easily store some data not exposed to VM, but also have
control what VM will see. And at the same time, it make it compatible
with existing services framework

When libvirt domain is not defined, it isn't running for sure.
This commit fixes the case when vm.is_running() appears anywhere in the
code used during libvirt xml building. In this case, it's mostly about
PCI device description for libvirt.
Do not initialize it only at qubes.xml load time, but re-read vm.kernel
property each time the path is constructed. While at it, add support for
vm.kernel set to 'None' - simply don't include modules.img (xvdd) then.
While at it, adjust implementation to specification: tags don't have
value, only one bit of information (present/not present).

This is required to get shutdown notification, when it wasn't initiated
by qubesd (for example 'poweroff' command inside of VM).
Libvirt event loop implementation must be registered before making
connection to libvirt, so move it to the beginning of main().
For now, only 'domain-shutdown' event is emited.
User session may not be started at all (for example no qubes packages
installed there), so don't block it in all the cases. Also this would
prevent running 'qubes.WaitForSession' service...
In practice, default value for 'gui' argument is False, so in most cases
user session will be ignored. Which doesn't matter in most cases -
especially for services called by qubesd.
Keep it uniform - QubesVM() object is responsible for handling
vm.dir_path, Storage() is responsible for handling disk volumes (which
may live in that directory
QubesOS/qubes-issues#2256
Allow specific pool implementation to provide asynchronous
implementation. vm.storage.* methods will detect if given implementation
is synchronous or asynchronous and will act accordingly.
Then it's up to pool implementation how asynchronous should be achieved.
Do not force it using threads (`run_in_executor()`). But pool
implementation is free to use threads, if consider it safe in a
particular case.
This commit does not touch any pool implementation - all of them are
still synchronous.

Management API gives access only to qubes.property. And this is
actually a good thing, so instead of extending it to access also
builtins.property, add a simple decorator to define read-only, stateless

qvm-ls tool (as all other tools) will be accessing properties through

0) All those methods are now awaitable rather than synchronous.
1) The base method is run_service(). The method run() was rewritten
using run_service('qubes.VMShell', input=...). There is no provision
for running plain commands.
2) Get rid of passio*= arguments. If you'd like to get another return
value, use another method. It's as simple as that.
See:
- run_service_for_stdio()
- run_for_stdio()
Also gone are wait= and localcmd= arguments. They are of no use
inside qubesd.
3) The qvm-run tool and tests are left behind for now and will be fixed
later. This is because they also need event loop, which is not
implemented yet.

Don't allow characters potentially interfering with qrexec. To be on the
safe side, allow only alphanumeric characters + very few selected
punctuations.
Split it into two functions: validate_name - context-less verification,
and actual _setter_name which perform additional verification in
context of actual VM.
Switch to qubes.exc.* exceptions where appropriate.
QubesDB daemon no longer remove socket created by new instance, so one
part of VM restart race condition is solved. The only remaining part is
to ensure that we really connect to the new instance, instead of talking
to the old one (soon to be terminated).

VM files may be already removed. Don't fail on this while removing a
VM, it's probably the reason why domain is being removed.
qvm-remove tool have its own guard for this, but it isn't enough - if
rmtree(dir_path) fails, storage.remove() would not be called, so
non-file storages would not be cleaned up.
This is also needed to correctly handle template reinstallation - where
VM directory is moved away to call create_on_disk again.

Just calling pool.init_volume isn't enough - a lot of code depends on

This helps hiding VM IP for anonymous VMs (Whonix) even when some
application leak it. VM will know only some fake IP, which should be set
to something as common as possible.
The feature is mostly implemented at (Proxy)VM side using NAT in
separate network namespace. Core here is only passing arguments to it.
It is designed the way that multiple VMs can use the same IP and still
do not interfere with each other. Even more: it is possible to address
each of them (using their "native" IP), even when multiple of them share
the same "fake" IP.
Original approach (marmarek/old-qubes-core-admin#2) used network script
arguments by appending them to script name, but libxl in Xen >= 4.6
fixed that side effect and it isn't possible anymore. So use QubesDB
instead.
From user POV, this adds 3 "features":
- net/fake-ip - IP address visible in the VM
- net/fake-gateway - default gateway in the VM
- net/fake-netmask - network mask
The feature is enabled if net/fake-ip is set (to some IP address) and is
different than VM native IP. All of those "features" can be set on
template, to affect all of VMs.
Firewall rules etc in (Proxy)VM should still be applied to VM "native"
IP.

core: start qubesdb as normal user, even when VM is started by root
On VM start, old qubesdb-daemon is terminated (if still running). In
practice it happen only at VM startart (shutdown and quickly start
again). But in that case, if the VM was started by root, such operation
would fail.
So when VM is started by root, make sure that qubesdb-daemon will be
running as normal user (the first user in group 'qubes' - there should
be only one).
