It takes few minutes to shutdown Qubes when some VMs were running. Additionally system is getting hot at that time (fans spin at 100%).

This problem was supposed to vanish in R3.0 (#903), but apparently it is still there.

One problem (fans at 100%) is because xenconsoled is stopped while some VMs are still running. But even when that is fixed, shutdown time isn't improved.
I guess it's about stopping uplink VMs (NetVMs, ProxyVMs) while still some VMs are connected there - which makes clean network detach impossible (from libvirt point of view).

Prevent stopping xenconsoled before shutting down all the VMs

Otherwise still running VMs will hang, consuming 100% CPU.

Kill remaining qubesdb-daemon instances after shutting down all the VMs
bae493d 
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

core: detach connected VMs when shutting down NetVM
83e73b4 
This is workaround for missing libxl/libvirt functionality: QubesOS/qubes-issues#1426

Also it should improve system shutdown time, as this is the situation
where all the VMs are shutting down simultaneously.

Fixes QubesOS/qubes-issues#1425

core: detach PCI devices before shutting down VM
2658c9a 
When VM is shutting down it doesn't disconnect PCI frontend (?), so when
VM is destroyed it ends up in timeouts in PCI backend shutdown (which
can't communicate with frontend at that stage). Prevent this by
detaching PCI devices while VM is still running.
