[one-users] unsure ubuntu 12.04 64 bits server, and ttylinux VM instance not running

[Qiubo Su (David Su)]

dear opennebula community,

1) i have already installed the ubuntu 12.04 64 bits desktop OS. to convert
it to 64 bits server, i "apt-get install tasksel", and "taskel install
server" to make it as "Basic Ubuntu server". is it ok to convert desktop to
server in this way for setting up a OpenNebula Cloud system? moreover,
after convert the desktop OS to server one, run "uname -a" and got "Linux
quicksu-P5K-SE 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012
x86_64 x86_64 x86_64 GNU/Linux" returned, is the generic kernel is ok for
server?

2) have setted up a Cloud system with opennebula 3.6.0 under the above
so-called 64 bits ubuntu 12.04 server, and create a ttylinux VM instance,
this instance is started well and in runn STAT at the beginning, as shown
in below:

oneadmin at onevmhost:~$ onevm list
    ID USER      GROUP    NAME            STAT   UCPU    UMEM
HOST             TIME
     0  oneadmin oneadmin  ttylinux           runn    3          64M
onevmhost      0d 07h57

however, after reboot the host, the ttylinux VM instance is in unkn STAT,
as shown in below:

oneadmin at onevmhost:~$ onevm list
    ID USER      GROUP    NAME            STAT   UCPU    UMEM
HOST             TIME
     0  oneadmin oneadmin  ttylinux           unkn    3          64M
onevmhost      0d 07h57

i have tried to make the ttylinux VM instance running again, but
unsuccessful.

it is much appreciated if anyone can help with the above.

thanks,
david su
