Description

VR advanced networking.

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/edithosts.sh

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.
