improve qemu performance
Qemu in yocto is emulator, and is slow when running huge task inside. E.g. running yocto build inside qemu. This article illustrate possible performance improvement to accelerate it
Enable KVM
If you have processor with VTx support, you can enable KVM so that virtualization rather than emulation is used for performance. Pls. refer following:
Add big memory
Sometimes, workload inside qemu requires huge memory. Fail to do this lead performance drop. So pls. add enough memory to qemu via -m 2048 (2G).
