There are three cases: + +``guest-reset=false`` + The guest is not allowed to reset the (physical) usb device. + +``guest-reset=true,guest-resets-all=false`` + The guest is allowed to reset the device when it is not yet + initialized (aka no usb bus address assigned). Usually this results + in one guest reset being allowed. This is the default behavior. + +``guest-reset=true,guest-resets-all=true`` + The guest is allowed to reset the device as it pleases. + +The reason for this existing are broken usb devices. In theory one +should be able to reset (and re-initialize) usb devices at any time. +In practice that may result in shitty usb device firmware crashing and +the device not responding any more until you power-cycle (aka un-plug +and re-plug) it. + +What works best pretty much depends on the behavior of the specific +usb device at hand, so it's a trial-and-error game. If the default +doesn't work, try another option and see whenever the situation +improves. + +record usb transfers +^^^^^^^^^^^^^^^^^^^^ + +All usb devices have support for recording the usb traffic. This can +be enabled using the ``pcap=<file>`` property, for example: + +``-device usb-mouse,pcap=mouse.pcap`` + +The pcap files are compatible with the linux kernels usbmon. Many +tools, including ``wireshark``, can decode and inspect these trace +files. diff --git a/hw/i386/microvm.c b/hw/i386/microvm.c index 754f1d0593..dc929727dc 100644 --- a/hw/i386/microvm.c +++ b/hw/i386/microvm.c @@ -631,6 +631,14 @@ static void microvm_machine_initfn(Object *obj) qemu_register_powerdown_notifier(&mms->powerdown_req); } +GlobalProperty microvm_properties[] = { + /* + * pcie host bridge (gpex) on microvm has no io address window, + * so reserving io space is not going to work.
