hi,all
i have 2 questions. both is related to spice usb redirect.
1. if i can control RW perm of usb device which is producted via
spice ? in order to control user's rw operation in guestVM .
AFAIK currently, there is no such control on Read and Write
permission.
But you can use the following redirection filter to limit usb
devices
usbdev is a whitelist of filter policies.
redirfilter
usbdev class='0x08' vendor='0x1234' product='0xbeef' version='2.00'
allow='yes'/
usbdev allow='no'/
/redirfilter
2.if user have several usbs, and plug them at the same time when
using spice client. if i can control which usb(s) can be accessed by
user in guestVM?
The virtual machine need to add one or more USB redirection
channelsredirdev first in to domain XML,
and these filter policies apply to them globally. For example:
devices
...
redirdev bus='usb' type='spicevmc'
address type='usb' bus='0' port='2'/
/redirdev
redirfilter
usbdev vendor='0x1234' product='0xbeef' allow='yes'/
/redirfilter
...
/devices
