So far so good, everything works as expected. What I want to do next is to update the debian image (apt-get update apt-get upgrade) and save it as a new image. Said and done. I first start the Debian VM, update it and then using onevm saveas I want to save the VM disk with ID 0 under a new name. # onevm saveas 5 0 debian-upd1 I mention that I ran the above command while the Debian VM was on. As far as I understand from documentation this is not a problem but the contents of the image are only created after the VM is shutdown gracefully (using onevm shutdown). So I did just that. # onevm shutdown 5 # onevm list ID USER GROUPNAME STAT CPU MEMHOSTNAME TIME 5 oneadmin oneadmin one-5shut 0 0K node02 00 00:09:18 I verify if the image is created using oneimage.

The Debian VM is gone, it is not listed anymore. onevm returns empty list. The Debian VM was the only one active. Is this normal behavior if you save the only disk the VM has?

It appears that with the new ONE_IMAGE MAD, this config value is gone, so we can't now add new images into the system as we had before. Right now we are using symlinks to fix this, but that's not a great solution. What is the appropriate upgrade in ONE 3 to match this functionality from ONE 2? Thanks, Rob -- Robert E.

Hi, Thanks for the reply ,. I have one doubt at the Export given in the installation doc . I.e *Export /srv/cloud to all the cluster nodes. For example, if you have all your physical nodes in a local network with address 192.168.0.0/24 you will need to add to your /etc/exports file a line like this: * * * *$ cat /etc/exports /srv/cloud 192.168.0.0/255.255.255.0(rw)* * * * In each cluster node create /srv/cloud and mount this directory from the front-end*. Here what does mounting exactly meant , is it required to mount /srv/cloud on to the host system from the from end system ..?

However, your first problem seems to be the fact that host02 cannot be resolved into an IP, or that it is not online. Check that your DNS are working so they can turn host02 into a valid IP address, otherwise add host02 translation to the /etc/hosts file or simply use the phisical node IP when running onehost create.
