Feature pages are design documents that developers have created while collaborating on oVirt.

Most of them areoutdated, but provide historical design context.

They arenotuser documentation and should not be treated as such.

hostusb

Note this hook should not be used ever since 3.6 since the passthrough support for USB was implemented natively as part of http://www.ovirt.org/develop/release-management/features/virt/hostdev-passthrough/
Do not use this hook!

hostusb adds host’s usb device/s to VM. This hook is useful for VMs that need to access USB devices attached to the hypervisor host, most commonly HASP plugs

VM XML changes:

    

Syntax:

     hostusb=0x1234:0xbeef&0x2222:0xabaa

This maps to:

     hostusb=VendorId:ProductId&AnotherVendorId:AnotherProductId... 

Note: The VM must be pinned to host and this hook will fail any migration attempt.

Host attached USB devices can be viewed with lsusb
