From: Michal Privoznik <mpriv...@redhat.com> In ed9e923c3c ("x86: move SMM property to X86MachineState", 2019-12-17) In v4.2.0-246-ged9e923c3c the SMM property was moved from PC machine class to x86 machine class. Makes sense, but the change was too aggressive: in target/i386/kvm.c:kvm_arch_init() it altered check which sets SMRAM if given machine has SMM enabled. The line that detects whether given machine object is class of PC_MACHINE was removed from the check. This makes qemu try to enable SMRAM for all machine types, which is not what we want.
