Xen devel - Oct 2006 - loop devices

Hi,

 

I have installed xen-unstable  change set 1150. I have 3 nics in my
system. 

My ifconfig  shows eth1, eth4 and eth5.

 

And a brctl show shows xenbr1 only.

 

When I try to create bridge 4

/etc/xen/scripts/network-bridge vifnum=4 start

 

Link veth4 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.

 

 

I tried increasing the loopback devices in the kernel boot command line
using netloop.nloopbacks=64

And also with max_loop=64, but neither worked.

 

Does anyone have any ideas of what could be wrong?

 

Thanks

- Padma

The former should work if the driver is built into your kernel. If it¹s not
I¹m not sure if module loading picks up options from the boot-time command
line. You might need to add a line to your modules.conf or to the line that
manually loads netloop.
