[one-users] Error with TM_LVM

[Anoop L]

Hi Jaime,

Thanks for the reply. My VM ID is 86 but still ONE uses 0 as identifier for
LV. Even the working VM with ID  is using lv-one--0.

I have already tried removing LV manually. I guess issue is that ONE is
trying to create the LV of same name and some how VM ID is not appended to
the LV_NAME.

One more things is when second VM fails it deletes the lv-one--0. Also any
idea how can I force set a VM template that a swap space/disk to be created
on LV.

Some more information:

 onevm list
   ID     USER     NAME STAT CPU     MEM        HOSTNAME        TIME
   85 oneadmin centos55 runn   0      2G     ast-wks-348 00 02:00:16
   86 oneadmin centos55 fail   0      0K     ast-wks-348 00 00:00:42


onevm show 86 gives:

Any help would be appreciated.
