https://bugzilla.kernel.org/show_bug.cgi?id=217307 --- Comment #10 from Michał Zegan (webczat@xxxxxxxxxxx) --- Okay, i have done more tests. So generally host-passthrough does not work, broadwell-notsx-ibrs, skylake-notsx-ibrs and also nehalem do not work, kvm64 doesn't work, qemu64 works. However, qemu64, even when I enable vmx and disable svm, boots without hyperv. Windows shows that second level adress translation is disabled. I tried to use libvirt's xml files and even qemu sources to see difference between qemu64 and broadwell-notsx-ibrs features, then enabled them all, the effect is exactly the same. I mean cpuid features. For these tests, everything like devices, secureboot, tpm, hyperv enlightenments, were enabled. -- You may reply to this email to add a comment.
