Known issues
|
||||
~~~~~~~~~~~~
|
||||
|
||||
List/attach/detach operations seem to work ok, devices are recognized by the target VM etc.
|
||||
But actual usage of the attached devices is unstable at best. In fact the only working device
|
||||
I saw was one USB stick (and this only after it took a minute to time out and reset the bus
|
||||
couple times). Kernel crashes are normal as well. I have not investigated these issues yet,
|
||||
I had similar experience with Marek's scripts.
|
||||
|
||||
* System keyboard / mouse are listed and can be detached away
|
||||
* Virtual USB devices (ones created by PVUSB frontend) may be listed
|
||||
* The installation/configuration is not persistent, not retained between reboots
|
||||
* No debugging / logging / audit trail
|
||||
* When an attached device is physically unplugged, USB port remains mapped but not displayed
|
||||
in the list. If device is plugged back it continues to work. Unlisted device cannot be detached.
|
||||
* We are not attaching actual devices, but USB ports (different behavior from VMWare, might be confusing)
|
||||
* After device is detached from the frontend and returned back to the backend it is not alwayws usable there
|
||||
* Code changing configuration of pvusb fe/be and vusb bind/unbind helper are located
|
||||
misc/xl-qvm-usb-attach.py misc/xl-qvm-usb-detach.py misc/vusb-ctl.py. These helpers are
|
||||
deployed into the backend domain. The initialization code is qubesutils.py in usb_setup(),
|
||||
should probably also be moved into an external helper. Perhaps the functionality of these
|
||||
external helpers should be merged into libxl? The is one catch is invokation of vusb helper
|
||||
in the backend domain -- now it relies on qubes-specific API.
|
||||
* After reboot attached USB devices are not listed by 'qvm-usb -l' until replugged.
