I just did a little test.  If my focus is on the VM, it gets the USB mount, and the host OS does not.  If my focus is on a host OS window, it gets the USB mount and the VM does not see it.  So that prevents two writers to the one device.

Really? If I plug in USB storage, I always have to futz around with the VM's settings, manually select "add new USB device", find the new USB storage device, and only then Windows 7 that's running in my VM sees it.

My base OS is F21/Xfce and the VM is also F21/Xfce.  This might have something to do with USB seeming to work right.


This might be a new virtual USB hardware "device" that I have to switch to, does anyone know this for sure? This is probably somewhat similar to how audio support evolved over time. When I set up my first Windows 7 VM, there was no audio passthrough from the VM to the real audio. I kind of let it go, after Googling that, on an off, for a year or so. A few releases of Fedora later, a second Windows 7 VM install suddenly had sound. Comparing the two VMs, the older one showed "Display: VNC", the new VM had "Display: Spice". After changing the older VM's setting, I suddenly had audio.

If KVM can now automatically grab USB storage if the VM has input focus, this would certainly be a very nice jump in functionality, if I could only figure out how to make it do that, now…
