Yes, quest OS can be on the same subnet. Just configure it like you would any windows server. You should propably check where that ip came from. My guess would be that it's "windows zero conf" or something like that. Basicly windows assigns that ip if there is no static configuration or dhcp availeable. Try assigning some ip from 192.168.1.0/24 subnet manually and go from there.

I don't understand how you would be able to ping form wondows but not the other way, other than windows firewall preventing it.

The windows server is on DHCP and it got 192.168.122.187/24 i have no dhcp server setup(only router but that gives 192.168.1.0/24)

the windows server can ping the routers and devices on 192.168.1.0 but from my router i cant ping 192.168.122.0/24

when i mean "is there a way that the the guest OS belong to the same network? so they can be communicate easily?i mean for the guest Os to be on the same subnet.

thnx for helping.....

The IP you get? Where do you get it? From DHCP or from windows?

You do know that xen only gives mac address for the virtual ethernet adapter? You need to either configure IP-address manually or have dhcp enabled on the virtual machine for it to get/have ip address. Also you need to have dhcp server on the network for it (dhcp) to work.

I dont know what you mean by "is there a way that the the guest OS belong to the same network? so they can be communicate easily?" but you can assign any ip address to virtual host, xen doesn't mind. If routing works/they are on the same network, everything should work just as it would with non virtualized servers.

ok so i have centos installed configured with xen...installation went smooth.

the centOS is on 192.168.1.1/24 network

i managed to install windows server 2003 but the ip i get is 192.168.122.187 /24

this is what i get from ifconfig

and other stuff

but the thing is the windows server can ping the 192.168.1.1 but devices on 192.168.1.0 cant ping the 192.168.122.0(cuase they dont know of this network)

is there a way that the the guest OS belong to the same network? so they can be communicate easily?
