I have tried to run the OS and I can confirm that some instructions that
require VMEXIT are not implemented. In your case that's 0F7F or MOVQ
(mem from mmxreg) from MMX. In my case that's 0F11 or MOVUPS(xmmreg1 to
mem) from SSE.
I'd recommend you to run -cpu host,-mmx,-sse for a while, but the kernel
of the OS explicitly complains that it won't run on CPUs without SSE
support.

Title:
HVF linux on OSX hangs 2nd time started after adding socket
Status in QEMU:
New
Bug description:
Robs-MacBook-Pro-2:~ robmaskell$ qemu-system-x86_64 --version
QEMU emulator version 3.0.0
Host: MacOS - 10.13.6
Model Name: MacBook Pro
Model Identifier: MacBookPro14,3
Processor Name: Intel Core i7
Processor Speed: 2.8 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 16 GB
Guest OS: Elementary Linux Loki 0.4.1, patched up to date
Command used to start QEMU:
qemu-system-x86_64 \
-name ElementaryLokiDev \
-machine pc,accel=hvf \
-cpu max \
-smp cpus=2,sockets=2,cores=1,threads=1,maxcpus=2 \
-numa node,nodeid=0 \
-numa cpu,node-id=0,socket-id=0 -numa cpu,node-id=0,socket-id=1 \
-m 8G \
-vga vmware \
-hda e4.qcow2
Symptoms: Started without the -smp / -numa commands to install the OS,
then added -smp / -numa and the machine boots and lscpu reports extra
cpu as expected. Restart VM and it hangs on startup. Remove -smp /
-numa and machine starts again.
