qubesd service is critical for Qubes usage, so even in case of critical
error crashing the whole service, make sure it is restarted.
Set delay to 1s (default 100ms), to allow other services to restart too,
if crash was caused by some other service (like libvirtd crash).
QubesOS/qubes-issues#2960
Since qubesd properly handle chained startup of sys-net->sys-firewall
etc, we don't need a separate service to start netvm explicitly earlier.
FixesQubesOS/qubes-issues#2533
This service currently does more harm (desync libvirt state with
reality) than good. Since we have qubesd, we may come back to
implementing it properly using libvirt events.
This all either have been migrated to core3, or is not needed anymore.
There is still qvm-tools directory with a few tools that needs to be
migrated, or installed as is.
This way it will work independently from where qrexec-policy tool will
be called (in most cases - from a system service, as root).
This is also very similar architecture to what we'll need when moving to
GUI domain - there GUI part will also be separated from policy
evaluation logic.
QubesOS/qubes-issues#910
Prior to this commit, the qubes-core.service inherited systemd's default
timeout value of 90 seconds. With slow hard disk drives, this caused the
dom0 shut-down sequence to proceed even if some VMs were still not fully
shut down at the time of dom0 shut down.
This commit aims to avoid this issue by setting the service stop timeout to
180 seconds.

Have dm-snapshot of dm-snapshot. The first layer is to "cache" changes
done by base volume holder (TemplateVM in case of root.img), the second
layer is to hold changes do by snapshot volume holder (AppVM in case of
root.img). In case of Linux VMs the second layer is normally done inside
of VM (original volume is exposed read-only). But this does not work for
non-Linux VMs, orr even Linux but without qubes-specific startup
scripts.
This is first part of the change - actual construction of two layers of
dm-snapshot, not plugged in to core scripts yet.

Otherwise qvm-create-default-dvm may fail to include it in
saved-cows.tar, which will lead to DispVM being not really disposable.
FixesQubesOS/qubes-issues#2200
This is no longer necessary since volatile.img is formated inside the
VM. This also fixes DispVM creation if the user sets a restrictive umask
for root. Maybe related to #2200.
The following list is bollocks. There were many, many more.

systemd-user-sessions.service is specicically for that, do not use hack
(plymouth-quit.service), which doesn't work when the service is
disabled.
FixesQubesOS/qubes-issues#1250
It may happen (especially when VM doesn't close cleanly and needs to be
killed) that qubesdb-daemon will not notice VM shutdown immediately.
Normally it would stop after 60s timeout, but speed it up in case of
system shutdown
QubesOS/qubes-issues#1425
This is part of fixing qvm-start.
qmemman was moved with minimal touching, mainly module names.
Moved function parsing human-readable sizes from core2. This function is
wrong, because it treats k/M/G as 1024-based, but leave it for now.
This is required to create VMs in process of building Live system, where
libvirt isn't running.
Additionally there is no udev in the build environment, so needs to
manually create /dev/loop*p* based on sysfs info.
When user logins, login script will try to connect all guid to all the
running VMs. If VMs are still booting at this stage, will never
automatically get its guid (until user tries to start some program
there). This can for example lead to lack of nm-applet icon.
When called from libvirt->libxl, there is libvirt lock taken on that
domain. Because of that, we can't access libvirt domain, so basically
any runtime information. Without that --offline-mode, script waited on
the lock and then was killed by libxl after a timeout - before actually
committing the changes.
