Had some trouble getting Centos x64 installed as a guest in my new Centos 5.5 x64 server using Xen (thanks again for all the help getting the hardware virtualization turned on and confirmed yesterday!).
When I chose OS Linux, and whatever they called the detailed OS subtype I chose the Red Hat Enterprise 5.4 and greater, and then tried to install Centos 5.5, the install started and I got into the graphics installer, but when it was supposed to start installing individual packages the whole virt-manager and console window hung. Three times, at that same point. (I was monitoring web traffic to the install files it was working from, and it wasn't fetching files, either).
When I selected just "RHEL 5", it installed (and I'm now running the package updater, and it may have hung there; we'll see).
I would have expected the rhel 5.4 and greater option to be the right one for Centos 5.5. Anybody have similar experiences? Or, even more interesting, contrary experiences?
