Betreff: interface tun0 does not exist!

 

Hello,

I can not setup any guest’s becose of missing interfaces.

/var/log/xend-debug.log:

Link veth0 is missing.

This may be because you have reached the limit of the number of

interfaces that the loopback driver supports.  If the loopback driver is

a module, you may raise this limit by passing it as a parameter

(nloopbacks=<N>); if the driver is compiled statically into the kernel,

then you may set the parameter using loopback.nloopbacks=<N> on the

domain 0 kernel command line.

Hardware: HP DL380 G5, 16G memory, 4 nic’s from type bnx2, eth0 – eth3 are all there.

ifconfig –a prints eth0,eth1,eth2,eth3,lo

With kernel parameter “loopback.nloopbacks=128” i have the same problem.

Again with loopback.nloopbacks= …32,48,128,164,256… always no tun0 or xenbr0.

What can be wrong here ?

Many thanks for any help.

Thomas
