If /var/run is on tmpfs (which is the case in fc18), its subdirs must be
recreated at each reboot. As we already have script for similar things, just
extend it.
Also make /proc/xen/xenbus user-accessible for xenstore reads/writes.
Fedora 18 doesn't have /etc/sysconfig/clock. Instead have /etc/localtime
symlinked to real timezone (instead of hardlinked like before), so now it is
easy to get destination TZ name.
No longer individual QubesVm attributes hardcoded in QubesVmCollection
(qubes.xml load). Now it is integrated to QubesVm attributes machinery. Also
QubesVmCollection have no longer hardcoded supported VM types - this will
greatly improve code extension possibilities.
This commit doesn't cover QubesVmCollection.add_*vm methods (which are broken
for now because of missing "collection" argument to QubesVm constructor). This
will be done in next commit.
This will ensure that /rw/config/rc.local is called after applying default
iptables rules, so it can safely modify it without the risk to be overridden
later by default ones.
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.
In most cases after vchan close program terminates (or reexec itself to wait
for next connection), so cleanup isn't needed (not sure how about evtchn and
shared pages...).
But in case of stubdom it is needed to cleanup before waiting for new
connection - we can't reexec agent there.
