Hi,
oneimage list show the image name(the one I gave during the saveas ) and its
ID
oneimage show 32 ->
ID : 32
NAME : NewTTyimage
TYPE : OS
REGISTER TIME : 09/10 16:14:03
PUBLIC : No
PERSISTENT : No
SOURCE :
/srv/cloud/var/images/1848ed1a68e486136993479d37bea2cbfb43462c
STATE : disa
RUNNING_VMS : 0
The image path location has set to default location only . i.e
/srv/cloud/one/var/images , but I could not see any image after executing
the saveas and shutdown commands ,.
And also there are no errors in the log file .
why this cant save the VM ..?
Note: I use nfs for transferring the image . yes I'm running oneadmin has a
sudo user .
