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 hype= rv. 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. --=20 You may reply to this email to add a comment.
