Most of the distributions will detect Athlon vs. Xeon, SMP versus UP, large vs. small amount of memory, etc. a kernel that is tweaked for that configuration will be installed (usually without the user having to specify). That's the point of my question! Why would these distrib ship the *base* kernel *with* Xen directly, so no need for reboot if you want Xen: just start the hypervisor and go! To run a Xen kernel you must also run the Xen hypervisor. There is overhead but it is generally very low especially when running only a single domain as you seem to be suggesting. So the question: what is the penalty if we run Xen *without* the hypervisor (so without virtual machines) -jec _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
