Re: [Xen-users] Creating a bridged network on CentOS for the xen hypervisor

M a little confused by your post. Are you saying you have no internet access in the host (xen)? Or the guest (maybe linux)?

If you create aguest machine without a networkinterface you might have the problem you are describing.

I think you have posted before - it is possble people might not understand exactly what you are asking - if you are still having the same issue .maybe provide some more detail / versions etc

Is the problem in the host or the guest? If you have internet wth no "ifcfg-eth0" how about posting the ifconfig before and after you add one?

Subject: [Xen-users] Creating a bridged network on CentOS for the xen hypervisor

Dear xen users,

I am asking about how to creat a bridged network on CentOS 6.4.. I have the Xen hypervisor installed and booted correctly but there is no internet access there.

I have followed the commands and steps in these links, but non of them worked for me:
1: http://www.eucalyptus.com/docs/3.1/ig/configuring_bridge.html
2: http://www.cyberciti.biz/faq/rhel-linux-kvm-virtualization-bridged-networking-with-libvirt/
3: http://www.banym.de/linux/centos/setup-bridge-device-on-centos

I have a problem that the ifcfg-eth0 file does not exist in my network-scripts directory; I searched the websites and they say I can just creat a new file with some parameters assigned, but when I do so; I lose the internet access. I do not know if that is the problem make me unable to create a bridged network correctly.

I am not an expert in these network stuff, so please help me.

I am connecting the machine on a LAN network in my lab. at the university.

Best regards and wishes,
Mohammad Altahat.
