Hi, thank you all for your answers.
Aaron, floating IP delegations from 192.168.22.0/24 and then translating to
public IP addresses is my backup plan if this won't work, but I really hope
that we can get it working :-)

no success.
What am I doing wrong here? I am in the phase of building a new

How do you guys back-up instance volumes, on what frequency, with a method
to suspend the instance, copy data and resume the instance?
Thanks!

there a way to change a
port ID of a running instance in nova? Since my instance is running and I
don't want to terminate it and boot it again. Or can I use this --nic

Hi,

some volume / partition changes?
In virsh I simply added a cdrom type device and it had a higher priority.

Don't any of you backup the data directly from the NFS? Will the image be
neccessarilly corrupt if I copy it via FTP while the instance is running?

What was the reason for abandoning the work? Is is related to the XtreemFS

Hi Giacomo,
sorry for a late reply.
It turned out that the major improvement was made through increasing
NFS packet size from 8k to 32k.
After that no more of those messages were shown and everything is
working just great :-)
Thank you everyone for your suggestions and ideas again.
