This is the article I am referring to http://www.howtoforge.com/using-xen-with-lvm-based-vms-instead-of-image-based-vms-debian-etch I try to install by debootstrap method and installation aborts in middle of the process. The error showing in /var/log/xen-tools/filename.log is Code: I: Retrieving Release E: Failed getting release file http://ftp.us.debian.org/debian/dists/lenny/Release Copying files from new installation to host. Copying files from /tmp/jUrDxM_Km2/var/cache/apt/archives -> /var/cache/apt/archives Done Done The installation of the new system has failed. The system is missing the common file: /bin/ls Done System installation failed. Aborting While I checked from browser link http://ftp.us.debian.org/debian/dists/lenny/Release I was able to get release file but some how debootstrap method is failing to get release file what can be cause of error?
