Except for the claim that windows 7 is in widespread use this
still applies today.
Is it still the case that the "-usb" QEMU option gives you the
old OHCI/UHCI controller? (My quick look at the source code suggests
it is.) If so, that's an unfortunate default, since it makes it very
easy to pick the non-security-supported bad config by accident.
It was still the case when I stopped maintaining usb and it is unlikely
it has changed since.
Could we make "-usb" give the PC machines an XHCI controller for new
machine version types ?
Sounds reasonable to me. libvirt has changed defaults years ago.
take care,
Gerd
