Thread: Ubuntu server hosting virtual machines (dhcp range problem)

hello all,

configuring network consists of physical machine , 10 virtual machines. physical machine running ubuntu server (11.04) , using qemu/kvm/virt-manager run virtual machines.

here problem. need physical host assign ip addresses in specific range, using dhcp, virtual machines. don't want range defaults to. however, when set in virt-manager (under connection settings, , create new virtual network desired ip range) error says can’t start network configured because interface eth0 in use.

gives!? tried changing settings on default connection using ‘virsh net-edit default’ , got same error. exact error message in virt-manager “error starting network: internal error network in use interface eth0”. advice @ on how fix this, or workarounds helpful.

thank you!

so, turns out if set bridge in /etc/network/interfaces file don't error more. however, can't connect internet either. lol. thoughts?

bridge set btw:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
address 192.168.0.10
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0

(except ips)
