Does anyone know if it''s possible to load an entire image into memory and run it with no disk access? If so, how would you do it? (Is the question just ridiculous?) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Copy it to /dev/shm/ and point the image location there on the config? I don''t see why it wouldn''t work, but I don''t think there is many reasons to run it completly from memory (sure, latency should be nice (dunno about the Xen overheard tho), but you cannot save the changes and the memory footprint is fairly big).

This usually only gives small usable space though, so if your concern is dom0 disk access you might want to look at nfs/iscsi root. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
