[libvirt] FYI; warning while compiling lxc_driver.c

[Chris Lalancette]

Just wanted to give a heads up that the LXC driver spits a warning when
compiling on i686; the exact warning is:

 gcc -DHAVE_CONFIG_H -I. -I.. -I../gnulib/lib -I../gnulib/lib -I../include
-I../include -I../qemud -I/usr/include/libxml2 -DBINDIR=\"/usr/libexec\"

lxc_driver.c: In function 'lxcGetSchedulerParameters':
lxc_driver.c:1211: warning: dereferencing type-punned pointer will break
strict-aliasing rules

Generally I would go and fix such things, but I didn't spend any time to look at
the code, and I don't have an LXC environment handy to test on, so I didn't want
to break anything.  I just thought I would point it out.
