I''d like to connect an external drive to one of my Xen boxes so I can send some backups that way; what''s the current status of USB or Firewire under Xen? I''m ok hooking it up to either a dom0 or domU; doesn''t make a big difference to me.

However, out of the box, at least with UHCI and EHCI (aka USB 2.0) host controllers, it works without a hitch for mass-storage devices. I would imagine OHCI should work as well. -- Derrik Pates demon@devrandom.net _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I would imagine OHCI should work as well.Some ppl had problems on dell hardware with enabled USB, sharing IRQs between USB HCI and other devices made the system unstable... Other than that, USB in dom0 should work just as well as in plain linux. /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You can use the PCI assignment if you want to give a domU direct access to a USB or Firewire controller and all its attached devices. Either way, you''ll need to add the appropriate drivers to your kernel config: we include USB support but not Firewire or USB Mass Storage drivers. There''s also code for plumbing individual USB devices through from dom0 to a domU but it''d not quite ready for primetime. Plumbing individual Firewire devices through in a similar way would be possible - just needs someone to write the code ;-) Cheers, Mark _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
