Thanks Dan! I was indeed missing some modules (I just switched to the 2.6.20 kernel series and didn't find a couple of the necessary switches in menuconfig). I'm still having problems with the networking.
If I try to start libvirt_qemud without have the bridge defined, I get this error:
smoyernew images # libvirt_qemud --system iptables: Invalid argument Failed to autostart network 'default': failed to add iptables rule to allow forwarding to 'virbr0' : Invalid argument
This indicates that iptables failed to add the stateful forwarding rules, eg this rule Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT all -- * virbr0 0.0.0.0/0 192.168.122.0/24 state RELATED,ESTABLISHED This says you're still missing some iptables kernel moodules. nf_conntrack_ipv4 nf_conntrack Are the relevant ones i believe.
If I create virbr0 and then start libvirt_qemud, I get this error:
smoyernew images # libvirt_qemud --system Failed to autostart network 'default': cannot create bridge 'virbr0' : File exists
Yep, manually creating virbr0 is a really bad idea & will ultimately not work, because you still need the iptables rules which were failing above.
