[one-users] problems connecting to VM using ssh

[tedbs]

I see two issues:

 

1) Try listen="localhost" in GRAPHICS. The IP address you used is not a valid address.

 

2) The virtual machines are managed by OpenNebula on the front end. The virtual machines run on different computers, the hosts. virsh list on the front end shows nothing. Try it on the host where the virtual machine is running.

I just found that there are no domains in virsh list.
Due to this, even if VMs are running, I cannot suspend and restart them, or everything else, because virsh has not a domain to call.
Maybe if I manage to connect to VMs, this problem will be solved too.

Hi there
I'm a researcher from università di Perugia, triying to create a cloud to make some tests.

I'm having some troubles connecting to VM

I manage to create a virtual machine, its state is runn and through virtual machine manager that the resources from node are taken.
But, I cannot connect via ssh to VMs, neither run one of these (VMM says "graphical console not configured for guest").
so, I tried to put in VM templates this

GRAPHICS = [
  type="vnc", 
  listen="192.168.0.0", 
  port="5858"
  ]

in order to see if I can connect via vnc, but if I add this, VM deployment fails.

If I do not use Graphics, VM submission is OK, logs doesn't show everything bad, but I cannot reach VMs, even ping fails.
If I use Graphics, submission will fail. This is oned.log

Probably, submission fails because the front end cannot ssh the virtual machine, so the problem is: why I can't connect to VMs using ssh, or even ping?
I tried using both ttylinux.img and ubuntu 10.04.img as image files, but nothing changed.

Please, give me a tip!!

Cheers
