StandaloneVM have no template to get clean volatile.img. Normally it is copied
from template during VM creation, but it can happen that image would not extx
(e.g. after backup restore). So create it from scratch.
Stay with original approach (restoring from clean image of template) for other
cases as it is much simpler (and perhaps faster).
This is more accurate name. Also "qubes-setupdvm" is already used in
some places, so change service name instead of changing that places (at
least qubes-core.service).
Same purpose as sudo rule - the user already can do almost all
administrative tasks and access all VMs data, so do disable annoying
password prompt (eg at system shutdown), which do not add any real
security layer.
This reverts commit 4b44f977db.
This doesn't actually fix the problem, because in %post new qubes.py is already
installed and maxmem=memory is no longer true.
HVM should have meminfo-writer disabled by default (and now have). But existing
VMs have it already enabled so it must be fixed now. Generic HVM isn't capable
of dynamic memory management.
Previously it was forced to always have maxmem=memory but it wasn't fully
correct because someone could install Qubes agents/PV drivers including
meminfo-writer and xen-balloon even in HVM so it should be possible to turn it.
%setup macro must be present in %prep to set variables required by
find-debuginfo script. Symlink is to place sources in nice
/usr/src/debug/%{name}-%{version} subdir instead of plain /usr/src/debug/core
(which can be ambiguous).
Additionally all packages need to have _builddir pointing at top src dir (in
core-dom0 it was dom0 subdir). And to cheat make about current dir (to have
%{name}-%{version} included in path) chdir must be done by shell, not make - so
can't use make -C.
This libs are required by both dom0 and VM so it's better to have it
separately. Previously in VM it was separate package, but dom0 have them
embedded in qubes-core-dom0, but qubes-core-vm-libs package was used to build
qubes-gui-dom0. Now we do not build all packages for all distros (especially do
not build core-vm package for dom0 distro, so gui-dom0 build fails), so make it
explicit which package is needed by which system.
When device is ejected by some VM (state=6, effectively inactive), it should be
removed from xenstore to free slot for some another device. This should be done
by libxl toolstack, but not implemented in xen 4.1 - AFAIR done in xen 4.2.
