Hallo Chris,
I am writing in English, so that everybody can understand it.

If I do a:

gfp@Tuxedo ~$ ps -ef | grep virtlog

it comes up with:

gfp       5233  5218  0 19:45 pts/0    00:00:00 grep --color=auto 
virtlog (the word "virtlog" is in red colour)

root@Tuxedo ~# ps -ef | grep virtlog
root      5396  5392  0 19:55 pts/0    00:00:00 grep --color=auto 
virtlog (the word "virtlog" is in red colour)

I don't know if that means virtlogd is running?
