Thanks everyone for the investigation thus far. I cannot reproduce the issue (using an IDE CD-ROM):
* QEMU: tested both the v2.10.1 release, and current upstream master (3d7196d43bfe, "Merge remote-tracking branch 'remotes/kraxel/tags/usb-20171023-pull-request' into staging", 2017-10-24) * OVMF: built from current upstream master (704b71d7e11f, "MdeModulePkg/Variable/RuntimeDxe: delete & lock MOR in the absence of SMM", 2017-10-10) QEMU script: > ISO=/mnt/data/isos/iso-windows/en_windows_10_enterprise_2015_ltsb_n_x64_dvd_6848316.iso > CODE=/home/virt-images/OVMF_CODE.4m.fd > TMPL=/home/virt-images/OVMF_VARS.4m.fd > > cp $TMPL vars18.fd > > /opt/qemu-installed/bin/qemu-system-x86_64 \ > -m 2048 \ > -M q35 \ > -enable-kvm \ > -device qxl-vga \ > -drive if=pflash,readonly,format=raw,file=$CODE \ > -drive if=pflash,format=raw,file=vars18.fd \ > -drive id=cdrom,if=none,readonly,format=raw,cache=writethrough,file=$ISO \ > -device ide-cd,drive=cdrom,bootindex=0 \ > -debugcon file:debug18.log \ > -global isa-debugcon.iobase=0x402 \ > -monitor stdio Wall clock time from QEMU invocation to first install screen: 9 seconds. Now, this script does not assign a GPU with vfio-pci, but I understand Dann didn't do that either, yet he managed to reproduce the issue. Can someone please paste a *minimal* QEMU command line reproducer , preferably without vfio-pci; even more preferably with just an IDE CD-ROM? (To my understanding, this is exactly how Dann reproduced the issue; see comment#17.) Also, from the comments thus far, it looks like edk2 commit 6fb8ddd36bde makes a difference under QEMU 2.10. However, it is not clear to me if the same edk2 commit makes a similar difference under QEMU 2.8. The original report mentions a full system upgrade, which (I assume) upgraded both OVMF and QEMU. Can someone -- who otherwise reproduces the issue -- please test OVMF, built from upstream edk2, under QEMU 2.8?
