-[Bug] "-ht" flag ignored under KVM - guest still reports HT
-
-Hi Community,
-We have observed that the 'ht' feature bit cannot be disabled when QEMU runs
-with KVM acceleration.
-qemu-system-x86_64 \
-  --enable-kvm \
-  -machine q35 \
-  -cpu host,-ht \
-  -smp 4 \
-  -m 4G \
-  -drive file=rootfs.img,format=raw \
-  -nographic \
-  -append 'console=ttyS0 root=/dev/sda rw'
-Because '-ht' is specified, the guest should expose no HT capability
-(cpuid.1.edx[28] = 0), and /proc/cpuinfo shouldn't show HT feature, but we still
-saw ht in linux guest when run 'cat /proc/cpuinfo'.
-XiaoYao mentioned that:
-
-It has been the behavior of QEMU since

-
-    set CPUID bits to present cores and threads topology
-
-that we cannot remove HT CPUID bit from guest via "-cpu xxx,-ht" if the
-VM has >= 2 vcpus.
-I'd like to know whether there's a plan to address this issue, or if the current
-behaviour is considered acceptable.
-Best regards,
-Ewan.
