Many thanks for trying it out.

Good news!

Have you set VM_DIR in $ONE_LOCATION/etc/oned.conf?

I haven't test the ssh scripts with the vmware server, and I'm afraid
that the DATASTORE path will be different (in ESX and ESXi they are
stored under /vmfs/volumes, and that's harcoded). I need to test it
under vmware server and probably make some changes. Meanwhile, if you
point me what is the path to the DATASTORE in your vmware server I may
be able to provide a quick patch.

OpenNebula doesn't offer VMware VM creation, you have to create it
manually using the VMware Infrastructure Client (VIC).

Assuming you have defined a network interface in your VM template
(otherwise OpenNebula will leave the NICs defined upon VM creation).
If so, take a look to the running VM with the VIC to see if any
network interface is defined.

My guess is that either there are none defined, or there is one
defined and assigned to eth1, in which case you will have to
reconfigure your ubuntu VM to configure that interface instead of
eth0.

Please do not hesitate to ask further doubts. VMware server and the
ssh scripts are the least tested configurations, but I am confident we
can get it working.
