https://bugzilla.kernel.org/show_bug.cgi?id=215964 --- Comment #3 from Sean Christopherson (seanjc@xxxxxxxxxx) --- Hmm, QEMU is clearing clearing "guest mode" to get the vCPU back into L1 at RESET, and IIRC QEMU will do KVM_SET_NESTED_STATE as part of its RESET emulation. My question about the 0xcf9 write still stands. Does the OUT get sent to QEMU and then something goes awry during RESET emulation? Or is the OUT forwarded to L1 as a nested VM-Exit? -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
