When I try to install CentOS 5.5 in a new VM, I get an error that the installer is unable to retrieve stage2.img. I have verified the URL and I am able to download this file from a web browser. I suspect it is a networking/routing issue, but I can't figure out what is wrong. This is a new install of XenServer 5.6 on a new server. This server is remote, so I don't have physical access to the box - only ssh access. Can anyone give me some tips on what might be wrong here? Do I need to do something special to get a net install to work? For what its worth, I see the same error trying to install Debian Woody using a similar process. Thanks.
