Use this configuration to run basic Zephyr applications and kernel tests in the QEMU emulated environment, for example, with the Basic Synchronization sample:
# From the root of the zephyr repository
west build -b qemu_cortex_m0 samples/synchronization
west build -t run
This will build an image with the synchronization sample app, boot it using QEMU, and display the following console output:

X86
The X86 QEMU board configuration is used to emulate the X86 architecture.
This board configuration provides support for an x86 Minute IA (Lakemont) CPU and the following devices:
HPET
Advanced Programmable Interrupt Controller (APIC)
NS16550 UART
Applications for the qemu_x86 board configuration can be built and run in the usual way for emulated boards (see Building an Application and Run an Application for more details).
