Hi
I have a openvpn network using *tap* interfaces. On the machines on the vpn network, I want to create VMs in such a way that they should all get on the vpn network.
-- I have tap0 as the openvpn interface
-- br0 as the bridge.
-- script to setup bridge and the add tap0
ifconfig tap0 0.0.0.0 promisc up
brctl addif br0 tap0
ifconfig br0 10.4.0.2 netmask 255.255.255.0 up
route add -net 10.4.0.0 netmask 255.255.255.0 br0
route add default gw 10.4.0.1 br0
-- I have turned firewall off.
-- I have the bridge script in place (which works when I bridge eth0)
Now when I create new VM, using the command line...
qemu-system-x86_64 -net nic,vlan=0,macaddr=00:16:3e:70:8f:33 -net tap,vlan=0 -hda /mnt/vm_data/test_xp.hda.disk.xm -m 256
The VM does not seem to get the IP address :( (may be dhcp request is failing)
---- brctl show ---
bridge name bridge id STP enabled interfaces
br0 8000.7e986235e99b no tap1
tap0
-- ifconfig

Has anyone done similar setup ? or can shed light on the issue?
Thanks

p.s. I do not want to install and config on all VMs if possible.
