I created a Xen 4.1 DomU (hvmloader) and installed Endian 2.5.1 - all worked well, but slowly.

To improve performance, I switched to a PAE-Kernel:
>smart install kernel-PAE

I changed the Xen-Settings to pygrub and netfront-ethernet-interfaces, so the endian DomU is starting paravirtualized and working well (I think pretty much faster than before).

/etc/businfotab is nor showing:
# Generated by ethconfig
eth0    XEN-eth0
eth1    XEN-eth1
eth2    XEN-eth2

But since I switched to paravirt. no Network Informations are shown anymore - just "NaN".
The same procedure worked well with Endian 2.4.1 !

I've seen, that the daemon collectd is now (2.5.1) using netlink plugin instead of interface plugin - may be this is the reason for the different behaviour compared to 2.4.1, but I am not such familiar with this details.

Has somebody managed to run Endian 2.5.1 paravirtualized and keeping the Network Information Dashboard workin?

It would be nice to share the configuration.

Its really sad to see that noone has assisted with your question.  Unfortunately I'm no help, however I confirm that the latest 3.3.0 ISO version was working fine...until I did a command line efw-upgrade (which completed OK) then I got the Status Traffic graphs stopped working and the interface stats above show NAN.  Have rebooted. Have reloaded the upgrade.
