Hi all, I have setup a 4 terminal Windows host with the explicit purpose of running 4 separate Windows machines. The machine is a dell t1600 upgraded with 16gb of ram and a 250gb ssd. The only thing on this machine is Virtualbox and GotoAssist. I have created a baremetal backup of a machine to VHD and copied that machine 3 times to get my 4 separate guest OS's (running windows 7). I have 4 keyboards, 4 mice, 4 inventory scanners, and 4 label printers hooked to the host. I have gone through the settings of each machine and set filters for the devices on each guest. I am seeing issues where (randomly) a guest will either forget its filtering or something of the sorts. Ex: Keyboards/Mice will stop working, Printers that are assigned to station 1 will print on station 3. I have installed the guest additions on each machine, but ended up uninstalling as the mouse pointer would not show on the guest machine with the guest additions installed. Other than that, it seems to be working well. To repair these issues, a reboot is issued and everything goes back to working. If there are any suggestions to keep this from happening I would greatly appreciate it
