Interestly, I did an ifconfig in the VM and I see the the Broadcast
and the Netmask are incorrect.<br>
<br>
# ifconfig<br>

So it looks like a virtual network configuration issue somewhere but
I can't put my hand on it.<br>

<div bgcolor="#FFFFFF" text="#000000"> Hello,<br>
<br>
I am trying to get the test ttylinux VM going after a few
days of putting together bits of documentation to get a
better understanding of KVM. So far the VM is running and I
am able to ssh into it from the Control Server and the Host
but I am unable to ping it from any other external IP. <br>
<br>
I checked the relevant FAQ:

Yes, I am able to ping and ssh the VM from the Control
