[Qemu-devel] [PATCH 1/2] guest-agent: keep persistent state on persistent storage

[Igor Mammedov]

GA was keepeing persistent state info in /var/run/qga.state
file. However it's lost after every reboot since /var/run
usually is located on tmpfs or cleaned on start-up.

Fix issue by keeping state file in /var/lib/qemu-ga/
directory, which is intended for keeping persistent
local state according to FHS.
