Launching VM

Description

SerenityOS VM is intended to run localy. Also it's possible to use VNC & SPICE to run SerenityOS VM remotely.

By default, SerenityOS VM is launched using direct kernel booting. It's possible to use GRUB rescue cd to avoid using additional files.

System is booted to grub recovery CD. Then user type few GRUB commands to boot SerenityOS from NVMe disk image:

    root=hd0
    multiboot /boot/Prekernel root=nvme0:1:0
    module /boot/Kernel
    boot

Instruction

After build you will get "_disk_image" file. You can rename it to serenity.img.
Build or download GRUB recovery CD disk image and place it in directory where SerenityOS disk image placed
check that Linux Kernel have support KVM virtualization.
check that QEMU version is 8.1.0 or newer.
run VM with QEMU

VM with SPICE server

To get remote connection with sound support run:

    qemu -device i82801b11-bridge,id=bridge4 \

Connecting to VM

SPICE connection

Connect by VNC-client to port 5901. You can use spicy or remote-viewer:

    spicy --uri=spice://192.168.1.125:5901
    remote-viewer spice://192.168.1.125:5901

Where 192.168.1.125 is remote server IP-adddress.

VNC connection

Connect by VNC-client to port 5901. You can use vncviewer:

    vncviewer 192.168.1.125:5901

Where 192.168.1.125 is remote server IP-adddress.
