Share memory

1. Prepare the Host System:

   You need to ensure the 9p kernel module is loaded:

   sudo modprobe 9pnet_virtio

2. Start the Arch Linux Live ISO with QEMU:

   Use this command to start the Arch Linux live ISO while sharing a directory:

   qemu-system-x86_64 \
   -enable-kvm \
   -m 2G \
   -cdrom /path/to/archlinux.iso \
   -fsdev local,id=fsdev0,path=/path/to/host/directory,security_model=none \
   -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare
   
   

   Here:

   • Replace /path/to/archlinux.iso with the path to the Arch Linux ISO on your host system.
   • Replace /path/to/host/directory with the path to the directory on your host system that you want to share with the guest.

3. Mount the Shared Directory in the Arch Live Environment:

   Once the Arch Linux live environment boots up:

   1. Ensure the 9p kernel module is loaded inside the live environment:

      sudo modprobe 9pnet_virtio

   2. Create a mount point:

      sudo mkdir /mnt/hostshare

   3. Mount the shared directory:

      sudo mount -t 9p -o trans=virtio,version=9p2000.L hostshare /mnt/hostshare
