Re: [Xen-users] network configuration on DomUs

[Pierre Peyronnel <pierre.peyronnel@xxxxxxxxx>]

Hello Hernan,

i'm not sure this is a Xen problem.

By the looks of it, you refer to IPv4 addresses but your ifconfig (on dom0 i guess ?) shows IPv6 addresses for all NICs and bridges except for eth0 and lo where it is also has IPv4.

Your .14, .16, .17 are nowhere to be seen...

My bet would be on a IP and/or routing setup issue. You should check these on SQL VM, but again what makes you think it is Xen related ?

Hi

I'm very new with Xen (/Debian)

I have 2 VMs running Windows: "Arch" and "Sql" -- static IPs

VM Arch: is ok, accessible thru VNC, Remote Desktop, see the network, etc

VM Sql : - just accessible thru VNC

      - once I log in, I don't see the network

      - pings don't reach peer

      - appear 4 network ports on Windows

the server has 4 NIC cards

the first, eth0, is used just for the server, with IP 10.0.11.13

the VM Arch should use eth1, with IP ...14

and VM Sql should use eth2 with IP 16, and eth3 (as configured in SQLServer) with IP 17

please, guide me

I inherit this problem, and am far from being an expert...

THANKS IN ADVANCE!!
