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.
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…
