Re: [openstack-dev] [nova] Question about USB passthrough
Hi, I have written a wiki about usb controller and usb-passthrough in https://wiki.openstack.org/wiki/Nova/proposal_about_usb_passthrough. Hope I can get your good advices.

Re: [openstack-dev] [nova] Question about USB passthrough
Yes, PCI devices like GPU or HBA are common resources, admin/user do not need to specify which device to which VM. So current PCI passthrough function can meet user scenarios. But USB devices have different user scenarios. Take USB key or USB disk as example, admin/user may need the content in USB device but not the device itself, so admin/user should specify which USB device to which VM. There are other things needed to be considered too, for example USB device may need a matched USB controller but not the default USB 1.1 controller created by qemu. I'm not clear about how to provide this function but still want to write a wiki so that more people can participate in the discussion.

USB key is an interesting scenario. I assume the USB key is just for some specific VM, wondering how the admin/user know which usb disk to which VM? --jyh ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
Re: [openstack-dev] [nova] Question about USB passthrough
Hi, It is a good implementation of USB redirection function of http://usbip.sourceforge.net/. But now I more concern about how to provide USB passthrough. Now that USB devices are used so widely in private/hybrid cloud like used as USB key, and there are no technical issues in libvirt/qemu. I think it a valuable feature in openstack. So, are there any further suggestions?

[openstack-dev] [nova] Question about USB passthrough
Hi, Boris and all other guys: I have found a BP about USB device passthrough in https://blueprints.launchpad.net/nova/+spec/host-usb-passthrough. I have also read the latest nova code and make sure it doesn't support USB passthrough by now. Are there any progress or plan for USB passthrough?
