It has been previously stated on this list that RHEL5 supports PAE (with Xen 3.0.3). How do we tell, given the Red Hat RPMS that go on with a default "virtualization" install, are those PAE or not? (I am trying to run 32-bit PAE domU''s on a 64-bit xen 3.1.0 host and I am wondering if the stock red hat kernel-xen-2.6.18 with xen 3.0.3 is good enough to get the xen virtual client instance up and then upgrade to xen 3.1 from there.) -- Thanks Steve Timm ------------------------------------------------------------------ Steven C.

If so, is there any change that has to get made in the xen.cfg of the client virtual machine to enable it when the machine starts?

Are you talking about upgrading the domU''s kernel to the one shipped with Xen 3.1? I don''t really think there''d be any point in that. In general, it''ll work just as well to stick with the RHEL XenLinux, and then you''ll be closer to RedHat''s default configuration. Cheers, Mark -- Dave: Just a question.
