[Qemu-devel] [Bug 1798451] Re: MMX emulation is missing on HVF Acceleration

[Roman Bolshakov]

** Summary changed:

- HVF linux on OSX hangs 2nd time started after adding socket
+ MMX emulation is missing on HVF Acceleration

** Description changed:

- 
  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.
