Hi,

I am running xen 2.0.7 on linux 2.6.xx (the suse10 rpms). 
After running eg. about twenty small test domU machines I can´t create any more
domU´s. xend-debug.log says it could not create the vif27.0 device and gets an
deferred error.

Testing a bit I found out "ifconfig" in dom0 refuses running! afaik the xen
network scripts rely on ifconfig and therefore must fail.

Is there a limit in linux or xen kernel about the number of network interfaces?
Or even a limit of domU instances xen can handle??

Thanks
Dirk
