Comment 8 for bug 1798451

Adding a ditto to this.

== Command and output ==

$ qemu-system-x86_64 -m 2G -hda mydisk.vdi -accel hvf -vga std
qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]
Unimplemented handler (7fe3aac905e8) for 0 (f 11)

This is for a customized Ubuntu install.

== Symptoms ==

Guest window repeatedly alternates between the desktop, then flickers to terminal with the following text:

/dev/sda4: recovering journal
/dev/sda4: clean, 93356/1264800 files, 1076062/5056592 blocks
[ OK ] Started xrdp session manager.
[ OK ] Started OpenBSD Secure Shell server.
[ OK ] Started Terminate Plymouth Boot Screen.
[ OK ] Started Hold until boot process finishes up.

== Host system ==

- macOS 10.14.6
- Bluetooth mouse and keyboard

Also, the workaround of using -cpu host,-mmx,-sse doesn't work (the guest appears to never even boot).
