Run IOU on OpenSuse converted from VirtualBox to Parallels.

Was tryin' to run IOU on OpenSuse converted from VirtualBox to Parallels.
Lessons learned:
1. Uninstall VirtualBox Guest Additions first.
2. Uninstall VirtualBox Guest Additions first. Seriously.
3. Edit Grub config file to mount hard disk devices by name not by aliases (of any kind).
4. After failing step 1 - manually fix /etc/fstab (-90 secs).
5. After addind new NIC(s) in Parallels to VM - update Yast settings.
6. Fix /etc/ssh/sshd_config to not use DNS (-20 secs).
7. Get to know -N option for telnet client (-15 secs).

All thanks are going to Wireshark (and Google as usually).
