Betreff: [Fedora-xen] 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
