Re: [Xen-users] Routed Xen networking

[Phil Lello <phil.lello@xxxxxxxxxxxxxx>]

Hi,

I managed to get this working by dropping the type=ioemu from the vif tuple, and building an ISO with the PV drivers. My issue turned out to be a problem with the emulated NIC.

I think the wiki for Windows2008 needs updating for Xen 4.4/4.5, as some of the config options have changed, although I'm not sure what the correct options would be for an emulated NIC.

I've not use routing mode very much but
http://wiki.xenproject.org/wiki/Xen_Networking#Associating_routes_with_virtual_devices seems to suggest that you don't need the /32 bit in the above. Not sure if it is harmful or not.

Have you enabled the sysctls mentioned in
http://wiki.xenproject.org/wiki/Host_Configuration/Networking#Routing ?

Since you are running a windows guest, do you have PV drivers installed?
Or if not then is there a vif4.0-emu device in dom0 which isn't being
routed?

If none of that produces any success then my next step would be
traceroute or mtr to see where the pings were actually going, maybe a
spot of tcpdump too.

Ian.
