[libvirt] [PATCH v2 0/3] Define XDG variables for hypervisor domains

[Erik Skultety]

v1 here:
https://www.redhat.com/archives/libvir-list/2019-March/msg00323.html

since v1:
As per conversation with Dan P.B:
- dropped XDG setting (apart from XDG_CACHE_HOME - we need that)
  for session QEMU
- dropped setting HOME for session mode (HOME is passed from the session)
- dropped previous patch 2 and decomposed the original patch into 2 units

So for v2, this is what the settings will look like:

system QEMU:
HOME=/var/lib/libvirt/qemu/domain-5-f-live \
XDG_DATA_HOME=/var/lib/libvirt/qemu/domain-5-f-live/.local/share \
XDG_CACHE_HOME=/var/lib/libvirt/qemu/domain-5-f-live/.cache \
XDG_CONFIG_HOME=/var/lib/libvirt/qemu/domain-5-f-live/.config \

session QEMU:
XDG_CACHE_HOME=/home/eskultet/.config/libvirt/qemu/lib/domain-4-f-live/.cache \

NOTE: This version doesn't contain the test changes in order to bring down the
patch size, so this won't compile, if you want to try it, see my github with
full changeset:
