Let XenD setup qemu logfiles none

Description Daniel Berrange 2008-02-27 13:30:25 EST
Description of problem:
The Xen qemu-dm process re-opens stderr and directs it to a logfile
/var/log/xen/qemu-dm-DOMID.log.

When libvirtd spawns QEMU guests though it expects to be able to capture
messages on stderr, and send them to its own logfile
/var/log/libvirt/qemu/{DOMNAME}.log

So, since Xen is capturing stderr already, when you launch qemu-dm via Xenner we
never get any log messages fed back to libvirt's logfile.

Xen's should qemu-dm should simply not capture the stderr. This functionality
should be moved into XenD itself, allowing calls of qemu-dm to deal with logs as
they see fit.
