I want to have CentOS 6.0 x86_64 as a dom0 xen host. During the installation of CentOS there are many options for installation: "minimal" "Basic Server"... "Virtual Host".. The question is: which one should I select? Is it "virtual host" or can I go with "Basic server" or "minimal" (which is the default)?
Virtual Host = Basic Server + virtualization, virtualization-client, virtualization-platform
Thus the first guess would be that Virtual Host is best suited; but looking at the RedHat virtualization guide the "virtualization-*" package groups probably mean KVM. Now, here you'll find information about Xen 4 and a RHEL dom0, including links to binary repositories. This suggests choosing "Basic Server", or just to follow the linked tutorial, they start with "Basic Server", too.
