[libvirt-users] Managed USB passthrough

[Michael Han]

Does the "managed" attribute of the hostdev element for a USB device
make a difference? The Domain XML Format docs has the following
sentence for the hostdev element:

If managed is omitted or "no", and for USB devices, the user is
responsible to call virNodeDeviceDettach (or virsh nodedev-dettach)
before starting the guest or hot-plugging the device, and
virNodeDeviceReAttach (or virsh nodedev-reattach) after hot-unplug or
stopping the guest.

Is that still accurate? The device seems to get passed through fine to
my LXC container without any dettach/reattach calls. But I'm seeing
some other strange USB behaviour in the guest and just want to see if
it's at all related to the managed attribute.

Cheers.
