...onfig adjusted for PV operation. I didn''t to write down which exact distro config file I used and what I changed, but it was either Fedora 8 or Debian lenny. I had to turn on Xen guest support (CONFIG_XEN) and set High Memory Support to 64GB (CONFIG_HIGHMEM64G, which turns on X86_PAE). I also turned off kvm support because my hypervisor happened to be an early 3.3-unstable whose cpuid reporting seems to be broken, and attempts by the guest''s kvm to use the CPU''s HVM support can crash the guest. The resulting config file is attached below. * Buil...
