[one-users] unable to start a VM

[Upendra Sharma]

Thanks Ruben,

I eventually debugged problem of ACPU being 0; but the VM is still not running

What was the problem with "onehost list"?
I
found out that my sudo on destination machines (obelix41 and obelix43)
required tty. So I disabled it (visudo and comment out requiretty) and
now the result is as shown below
onehost list
 HID NAME                      RVM   TCPU   FCPU   ACPU    TMEM    FMEM STAT
   0 obelix43                    0    800    799    800 4192256  130048   on
   1 obelix41                    0    800    799    800 4192256  130048   on
The Surprising thing is that although sudo was not working remotely there was no error reported in oned.log.
Anyways, that seems to be clean now .... but the problem still remains.

My VM is always on the STATUS of pending.

 onevm list
  ID     NAME STAT CPU     MEM        HOSTNAME        TIME
   3   TestVM pend   0       0                 00 00:10:13

I
do not know what is happening now. None of the logs report any error.
Is there is quick fix which you know  (the fact is that I do not know
ruby).
do you think that since this is a beta version so I have
unearthed some untested portion of code and I should switch to the
stable version, i.e. 1.0?

thanks,
-upendra
