[one-users] ttylinux via ssh not accessible any more after migrate / suspend -> resume

[Viktor Mauch]

hello javier,

one more time,

I'm now working with OpenNebula 2.0beta with the KVM Hypervisor (head 
node and cluster nodes are based on 10.04). I tried to play with the 
supported ttylinux image form the ONE website. Starting the machine and 
login via ssh is no problem. After Stop -> Resume the machine is still 
available via network.

But if I perform a migration of the the machine or suspend -> resume, 
the network conncetion is gone (ping / ssh find no aim). I looked via 
VNC into the VM, and everything looks ok, the eth0 device is still 
configured right, but also no possibility to ping something others 
outside the VM. Restarting of the network did not solve the problem. The 
log files are clear. All physical hosts are in the same switch.

Does anyone have an idee what goes wrong??
