Revision 7881f96cac4d420c94e62a4e1eea243899a7052e authored by Jim Mattson on 14 September 2017, 23:31:40 UTC, committed by Paolo Bonzini on 15 September 2017, 14:57:14 UTC
After a successful VM-entry, RFLAGS is cleared, with the exception of bit 1, which is always set. This is handled by load_vmcs12_host_state. Signed-off-by: Jim Mattson <jmattson@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
