<br>
I have changed localhost in Graphics as you said and I managed to see ttylinux
with vnc, but still I cannot connect via ssh, and if I submit any other image,
then I got the same error. <br>
Funny, isn't it?<br>
<br>
Maybe I can't run any other VM because of Ubuntu 10.04 has a bug about kvm-pxe
package.<br>
<br>
https://bugs.launchpad.net/ubuntu/+source/etherboot/+bug/574524<br>

Anyway, I'm trying to submit this template<br>

on the same network where ttylinux runs.<br>
Something's worng in the template?</span></p>

Subject: problems connecting to VM using ssh<br>
Date: Fri, 4 Jun 2010 10:30:41 +0200<br>
<br>
Hi there<br>
I'm a researcher from università di Perugia, triying to create a cloud to make
some tests.<br>
<br>
I'm having some troubles connecting to VM<br>
<br>
I manage to create a virtual machine, its state is runn and through virtual
machine manager that the resources from node are taken.<br>
But, I cannot connect via ssh to VMs, neither run one of these (VMM says
"graphical console not configured for guest").<br>
so, I tried to put in VM templates this<br>
<br>
GRAPHICS = [<br>
type="vnc", <br>
listen="192.168.0.0", <br>
port="5858"<br>
]<br>
<br>
in order to see if I can connect via vnc, but if I add this, VM deployment
fails.<br>
<br>
If I do not use Graphics, VM submission is OK, logs doesn't show everything
bad, but I cannot reach VMs, even ping fails.<br>
If I use Graphics, submission will fail. This is oned.log<br>

<br>
<br>
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?<br>
I tried using both ttylinux.img and ubuntu 10.04.img as image files, but
nothing changed.<br>
<br>
Please, give me a tip!!<br>
<br>
Cheers <br>
