I have a windows xp guest working using qemu-kvm with "-net nic -net user". I'm attempting to use bridging. I've created the br0 interface and modified my eth0 file. Bridging seems to be working. I'm able to access the machine from other places. When I try to start qemu-kvm with these options "-net nic,macaddr=11:22:33:44:55:66 -net tap" I get this error: warning: could not configure /dev/net/tun: no virtual network emulation Could not initialize device 'tap'
These errors are in /var/log/messages. setroubleshoot: SELinux is preventing qemu-kvm (qemu_t) "read write" to tun (virt_image_t). For complete SELinux messages. run sealert -l 2ca593ab-ec5f-407b-a6d5-291abc0b2e29

Any suggestions?

You follow the instructions here?

Strange. Do what it says and run 'sealert -l ...' to help figure out what's wrong.
Does e.g. 'restorecon /dev/net/tun' help?
Cheers, Mark.
