I've even gotten Windows NT 4.0 Workstation to run within oVirt. (With PCI passthough

Windows 7 is still something I would expect any modern VM software to support. (As of this
Never mind that one of the reasons to run a VM in the first place is to run (older)
software that needs a specific environment to run. Which the main host environment cannot
support. I can understand RedHat wanting to reduce it's workload, but developers
constantly deprecating support is one of the bigger problems with OSS at the moment. Many
people go the OSS route initially for legacy support. (Can't afford the upgrade
treadmill.) Cutting that out and forcing people to buy new every time is just going to
make them stick with the new thing they bought. While creating a negative view of OSS that
they will then spread to others. oVirt as a community project shouldn't be encouraging
As for the original question...
You might try removing any extra USB drivers you have installed. (Especially the NEC
drivers if you've still got them in there.) Also is that hook from your previous mail
Yes, since the there is no way to make qemu-xhci work on Windows 7, i have to change to
nec-xhci. It mostly works(usb redirection by spice) after i installed the nec usb3.0
controller driver, except "Eject USB storage"
And actually it will become on response only if i cliked "Eject" on the windows
it works if i Eject USB storage from the File Explorer.
If it is, you can try creating a new VM and attach the existing disk
to it. (So you won't have to reinstall Win7 again.) That should give it a default
If all else fails, you may need to reinstall Win7 under a new VM profile to get it
If you absolutely need USB3 support under Win7, you could try doing a passthrough of a
USB controller on the host system. (You won't be able to use that controller on the
host if you do.)
I convince It works but not my option.
That would allow you to use a PCI USB controller card with the
appropriate drivers for Windows 7. Granted it's counter to my point above, but at the
moment, I don't see how Windows 7 would get USB3 support from qemu / KVM. Short of
someone taking the time to write a new virtio driver from scratch. Which has been asked
for previously to no avail.
