I read a lot of tutorials (or at least try to be) but none is able to explain well how to configure networks for xen host.
my Dom0 has two interfaces eth0
(real interfaces) and virbr0
(I guess was created by bridge-utils )
eth0 192.168.1.254 #is static
virbr0 192.168.122.1 #i dont know where is the conf
Tutorials only indicate:
Edit
/etc/xen/xend-config.sxp
and append this lines(network-script network-bridge) (vif-script vif-bridge)
setup
vif
in thedomU.cfg
file... vif = ['ip = 192.168.1.100'] # this is the ip i want ...
setup interface on Guest
/etc/network/interface
the guest is a Ubuntu amd 12.04 setup with debootstrap utilityauto eth0 iface eth0 inet static address 192.168.1.251 gateway 192.168.1.1 netmask 255.255.255.0
but i can't access to DomU network.
aditional info
$ brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.000000000000 yes
Ubuntu 12.04.1 LTS x86_64
CPU: Xeon 5150 @ 2.66Ghz (x2)
RAM: 20GB (Dom0 1024M)
Note: Xen was installated with sudo apt-get install xen-utils-4.1 xenwatch xen-tools xen-utils-common virtinst virt-viewer virt-manager bridge-utils
solution works only with xl toolstack
I configured my network as follows and seems to work well (apparently)
auto eth0 xenbr0
iface eth0 inet manual
iface xenbr0 inet static
bridge_ports eth0
bridge_stop on
bridge_maxwait 1
address 192.168.1.254
netmask 255.255.255.0
gateway 192.168.1.1
