[Xen-users] How do you manage your domU kernel modules?
Just doing Xen 3.0.0 to Xen 3.0.2 upgrades here, and realising that copying the modules for the new kernel into all of the domUs is a massive pain. What do people do to alleviate this pain? NFS mount in all the domUs? Manual copying? Some sort of pre-boot autocopy? Some other clever way? I''ve got a mix of self-managed and customer-managed VMs, which complicates matters slightly. Keen to hear people''s ideas, as I really can''t identify a clear winner from the options I can think of -- but then, I''ve got no practical experience with most of them, so I don''t know all the benefits and drawbacks. - Matt _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

There usually isn''t a need, however. I only use a few for GFS or IPVS, but Gentoo portage builds them for me in each domU that needs them. -- Christopher G.
