Re: [libvirt] [PATCH] qemu: include hostname in QEMU log files

Often when debugging bug reports one is given a copy of the file from /var/log/libvirt/qemu/$NAME.log along with other supporting files. In a number of cases I've been given sets of files which were from different machines. Including the hostname in the QEMU log file will help identify when the bug reporter is providing bad information. Signed-off-by: Daniel P.
