How to setup "public bridge" in KVM?

How to setup "public bridge" in KVM?

[Zhao Forrest]

Hi experts,

I tried to setup VM network by following the instructions at
http://kvm.qumranet.com/kvmwiki/Networking. In particular I tried to
setup "public bridge", so I need /usr/sbin/tunctl. However I could not
find tunctl on my RHEL5.1 system. I also searched tunctl on CD image
and by google, but didn't find a RPM package including
/usr/sbin/tunctl.

Could you advise on how to configure "public bridge" under RHEL5.1?

Thanks,
Forrest

I updated the wiki with instructions for creating a bridge using
standard /etc/sysconfig configuration.
Use
http://kvm.qumranet.com/kvmwiki/Networking#head-db463ce47b5869c6771a265fc7c1547920d9a74a
and solution #1

If you want to go with the public bridge option usermode linux tools has tunctl.
e.g., http://www.user-mode-linux.org/cvs/tools/tunctl/

Dor and David,
Thank you for the advice. Now my guest OS could communicate with the
external world :)

Thanks,
