I installed a fresh R2.0 (after fighting R3.0 for 2 weeks now), and out of the box, everything worked fine (e.g. browsed using disp1 firefox).
Upgraded dom0 and the fedora template, reboot, and then no network from disp vm.
Checking further, I can confirm that netvm sees the internet (ping).
firewallvm sees netvm (10.137.1.1, as well as the dhcp address) and other vms (10.137.2.8), but not the internet nor my local router that runs the dhcpd.
other vm (10.137.2.8) see only firewallvm (10.137.1.5), but not netvm (10.137.1.1) nor the internet.
iptables --list in firewallvm looks OK (e.g. on chain FORWARD there is also ACCEPT for all ports from other vm to anywhere).
/proc/sys/net/ipv4/ip_forward is 1 both in netvm and firewallvm.
where should I look next?
