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

When libvirtd spawns QEMU guests though it expects to be able to capture
messages on stderr, and send them to its own logfile

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.
