Hello, I''m getting this message every time I start xend. If I go to /dev/xen, there it is blktap0, but if I use tap:aio: option to load domU file, at boot process I get a lot of errors, like "fd not found, patch aio_poll not implemented" or something like this. Where can I search info about that? I found little info in google... Kind regards, Ignacio. -- View this message in context: http://www.nabble.com/-dev-xen-blktap0-already-exists-tf4889370.html#a13995130 Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

It sounds like you''re somehow missing that patch, but I''m not clear how that could have happened. Where did your Xen install come from? Compiled yourself, distro kernel, or ... ? Have you made any tweaks to the setup that might be relevant? Cheers, Mark> Where can I search info about that?
