Hi Troy & Connie, paravirt installs of 4.8/64 are broken. The installer claims that the boot media do not match the install tree. The .buildstamp in 4.8/x86_64images/xen/initrd.img looks like this: 200906191446 Scientific Linux 48 SL while in images/SL/pxeboot it's 200907070939 Scientific Linux 48 SL I tried to modify the timestamp, which makes it possible to start the installation with that image, but then it fails with other weird errors (not enough space on /). Do you have a working initrd for xen pv installs around? Thanks, Stephan -- Stephan Wiesand DESY -DV- Platanenallee 6 15738 Zeuthen, Germany
