Tiny Code Generator
It sucks ...
# Single thread
qemu-system-x86_64 -cdrom ubuntu-20.04-desktop-amd64.iso -boot once=d -m 1G
# Multithread
qemu-system-x86_64 -accel tcg,thread=multi -cdrom ubuntu-20.04-desktop-amd64.iso -boot once=d -m 1G
Intel HAXM
Need to install Intel HAXM first, and disable Hyper-V.
If Docker Desktop was installed, this is not a good solution.
qemu-system-x86_64 -accel hax -cdrom ubuntu-20.04-desktop-amd64.iso -boot once=d -m 1G
Failed to open the HAX device!
Open HAX device failed
Failed to get Hax capability:6u
No accelerator found.
Windows Hypervisor Platform (recommended)
# with Windows Hypervisor Platform - good!
qemu-system-x86_64 -accel whpx -cdrom ubuntu-20.04-desktop-amd64.iso -boot once=d -m 1G
Windows Hypervisor Platform accelerator is operational
