Hi Pete, I had the same error. Some mirrors couldn't be donwloaded from. I had success with the mirror that is in the virt-install man's page, but it's not good. Then I'd made the download of the whole mirror and done it in localhost, and it worked. If you have success doing this, post here please. I wanna know too. <div class="gmail_quote">On Wed, Jun 4, 2008 at 4:12 PM, Pete Kay <<a href="mailto:petedao@gmail.com">petedao@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, When trying to install Cent domU on fedora 8 dom0, I am getting the following error.
