Install OVMF from Gerd's RPMs: http://www.kraxel.org/repos/ Create two small disks and copy different contents to them: unix2dos <<<"file 1" >f1.txt unix2dos <<<"file 2" >f2.txt qemu-img create -f qcow2 test1.img 64M qemu-img create -f qcow2 test2.img 64M guestfish -a test1.img -a test2.img run part-disk /dev/sda mbr mkfs vfat /dev/sda1 mount /dev/sda1 / copy-in f1.txt / umount / part-disk /dev/sdb mbr mkfs vfat /dev/sdb1 mount /dev/sdb1 / copy-in f2.txt / umount / q Start qemu: qemu-system-x86_64 \ -enable-kvm \ -m 1024 \ -L /usr/share/edk2.git/ovmf-x64 \ -bios /usr/share/edk2.git/ovmf-x64/OVMF-pure-efi.fd \ -device cirrus-vga \ -display vnc=localhost:0 \ -monitor stdio \ -S \ -debugcon file:/tmp/test.debug \ -global isa-debugcon.iobase=0x402 \ -net none \ -device usb-ehci,id=ehci \ -drive if=none,id=drive1,file=test1.img \ -drive if=none,id=drive2,file=test2.img This will start a VM that is paused and has - an EHCI controller, - no disk visible to the guest (the -drive options configure the backend (ie. host side), - a cirrus VGA card available via VNC, - and the qemu command monitor connected to stdio. Connect to the dispaly with vncviewer, issuing the command on another terminal: vncviewer localhost:5900 Unpause the guest using the qemu monitor: cont The UEFI shell should soon be running in the VM. Verify the mapping table -- no USB sticks should be visible: map -v It's time to attach the USB disk(s). Exit the UEFI shell, then while at the OVMF text-UI, issue the following two commands at the QEMU monitor: device_add usb-storage,id=stick1,bus=ehci.0,drive=drive1 device_add usb-storage,id=stick2,bus=ehci.0,drive=drive2 Launch the UEFI shell again from the OVMF text-UI, then enter map -v The two disks / files should be available as FS0:\F1.TXT and FS1:\F2.TXT. Exit the shell, and detach the 2nd disk at the QEMU monitor: device_del stick2 Re-launch the shell -- only the first disk should be available: map -v [...] type FS0:\F1.TXT file 1 type FS1:\F2.TXT Error. The file 'FS1:\F2.TXT' did not open. During testing, you can follow the edk2 EHCI/USB messages in "/tmp/test.debug" . For example, the disconnect (initiated by the "device_del" qemu command) generates the following for me: UsbEnumeratePort: port 1 state - 100, change - 01 on 3E8F5E18 UsbEnumeratePort: Device Connect/Disconnect Normally UsbEnumeratePort: device at port 1 removed from root hub 3E8F5E18 UsbDisconnectDriver: old TPL is 8, 3D659018 Success to stop non-multi-lun root handle UsbDisconnectDriver: TPL after disconnect is 8, 0 UsbRemoveDevice: device 2 removed UsbEnumeratePort: device disconnected event on port 1 EhcClearRootHubPortFeature: exit status Success And scrolling a bit back, 3E8F5E18 stands for the root hub: UsbRootHubInit: root hub 3E8F5E18 - max speed 2, 6 ports UsbBusStart: usb bus started on 3EA08498, root hub 3E8F5E18 [...] Connecting the disks generates another bunch of messages etc. Laszlo ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
