My bioinf team think of moving from ubuntu server 8.04 guest to 10.4. I 
have tried to run 10.4 but cannot start it. upstart patch and 
configuration given on VS website didn't work.  when I ps aux in guest I 
got continuous root (.....) init. so next step was to compile a newer 
kernel  so i've  decided  to check the  long support 2.6.32 line.  on 
this server 10.4 VS starts but when i ssh to ex. stats host in comand 
prompt  betasms (guest - 10.4) the same when I ssh to any other guest.

Yes i realized it is only vs with 10.4.
