Cloudmin users running 64-bit Xen host systems can now download 64-bit images for CentOS 6, Debian Squeeze and Ubuntu 10.04. Also available are updated 64-bit images for CentOS 5.7. Because Xen VMs need to be the same architecture as the host system, these images need to be downloaded separately from the regular 32-bit images.
To download the latest images, login to Cloudmin as
root and go to Cloudmin Settings -> New System Images. Then click Available for download , check the boxes next to the images you want to use, and click Download Selected Images.
