[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] No connection in DomUs with network-route
Hi,
I would like to know if somebody can point me out how to configure
several DomUs in a private LAN (for example 192.168.100.0/24) and one
DomU with two interfaces (one - 192.168.100.0/24 and two - internet).
So far I have enabled in xend-config.sxp:
(network-script network-route)
(vif-script vif-route)
My config files have:
/mnt/VM/1.cfg:vif = ['ip=192.168.1.3']
/mnt/VM/2.cfg:vif = ['ip=192.168.1.4']
/mnt/VM/3.cfg:vif = ['ip=192.168.1.5']
