    in /etc/dhcpentries.txt we had:
    This sed matched unexpectetly "songlog-1" as well when "log-1" was processed, resulting
    missing dhcp entry for songlog-1.
    Also fixed other potenials problems relating to sed matching.

> We experienced an issue when a few VMs were started at a time, some of them and always
the same ones did not receive a IP from DHCP. 
> After a debuging, we identified the problem in this sed command in 
> ./systemvm/patches/debian/config/opt/cloud/bin/
> the VM which was not in /etc/dhcphosts.txt was named:
> songlog-1
> When another VM was started named "log-1" the "songlog-1" entry was removed unexpectedly.
