+Usage: $(basename "$0") [OPTIONS] [QEMU_ARGS...]
+
+Options:
+  --use-host-qemu        Use system-installed QEMU instead of Yocto's runqemu
+  --vm-count=N           Number of virtual machines to launch (default: 1)
+  --help                 Show this help message and exit
+
+Arguments (QEMU_ARGS):
+  Additional arguments will be passed directly to each QEMU instance.
+
+Examples of QEMU_ARGS (you can use other valid options too):
+  -m 512M                Set VM memory size to 512 MB
+  -smp 2                 Set number of CPU cores to 2
+  -cpu sifive-u74        Use specific RISC-V CPU model
+  -bios none             Do not use BIOS/firmware
+
+Notes:
+  - Launching multiple VMs (vm-count > 1) is **only supported with --use-host-qemu**.
+  - For any VM count (even 1), SSH ports must be listed in 'ports.conf' (one port per line).
+  - With --use-host-qemu:
+      - Each VM will use its own copy of the root filesystem (in 'build/vm_images').
+      - SSH port forwarding is enabled (hostfwd=tcp::PORT-:22).
+  - Without --use-host-qemu:
+      - Only a single VM can be launched using Yocto's 'runqemu'.
+      - Port forwarding and rootfs copying are not used.
+  - VM logs are saved as 'vm_0.log', 'vm_1.log', etc.
+  
+Examples:
+  $(basename "$0") --vm-count=2 --use-host-qemu -m 1G -smp 2
+  $(basename "$0") -m 256M  # Launch single VM using runqemu

+# Сборка собственного слоя Yocto для кластера (meta-cluster)
+## 1. Подготовка окружения
+### Установка зависимостей (если не установлены)
+```sh
+sudo apt update && sudo apt install -y gawk wget git diffstat unzip texinfo gcc g++ \
+    build-essential chrpath socat cpio python3 python3-pip python3-pexpect xz-utils \
+    debianutils iputils-ping python3-git python3-jinja2 libegl1 libsdl1.2-dev pylint \
+    xterm python3-subunit mesa-common-dev zstd liblz4-tool
+```
+
+### Клонирование Yocto и слоев
+```sh
+mkdir ~/yocto-riscv
+cd ~/yocto-riscv
+git clone -b kirkstone git://git.yoctoproject.org/poky.git
+git clone -b kirkstone https://github.com/riscv/meta-riscv.git
+git clone -b kirkstone https://git.openembedded.org/meta-openembedded
+git clone -b kirkstone git://git.yoctoproject.org/meta-virtualization
+```
+
+### Инициализация окружения Yocto
+```sh
+cd poky
+source oe-init-build-env
+```
+
+---
+
+## 2. Создание собственного слоя `meta-cluster`
+```sh
+cd ~/yocto-riscv
+bitbake-layers create-layer meta-cluster
+```
+Добавляем слой в `bblayers.conf`:
+```sh
+nano ~/yocto-riscv/poky/build/conf/bblayers.conf
+```
+Добавляем строку:
+```
+BBLAYERS += "${TOPDIR}/../meta-cluster"
+```
+
+---
+
+## 3. Создание заглушек для `controller` и `unit`
+
+### `cluster-controller`
+Создаем папку и файл рецепта:
+```sh
+mkdir -p ~/yocto-riscv/meta-cluster/recipes-cluster/controller
+nano ~/yocto-riscv/meta-cluster/recipes-cluster/controller/cluster-controller.bb
+```
+Добавляем следующий код:
+```bitbake
+DESCRIPTION = "Cluster Controller Stub"
+LICENSE = "MIT"
+LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
+
+SRC_URI = "file://controller.sh"
+
+do_install() {
+    install -d ${D}/usr/bin
+    install -m 0755 ${WORKDIR}/controller.sh ${D}/usr/bin/controller
+}
+FILES:${PN} += "/usr/bin/controller"
+```
+
+Создаем заглушку `controller.sh`:
+```sh
+mkdir -p ~/yocto-riscv/meta-cluster/recipes-cluster/controller/files
+nano ~/yocto-riscv/meta-cluster/recipes-cluster/controller/files/controller.sh
+```
+Добавляем:
+```sh
+#!/bin/sh
+echo "Cluster Controller is running"
+```
+Делаем файл исполняемым:
+```sh
+chmod +x ~/yocto-riscv/meta-cluster/recipes-cluster/controller/files/controller.sh
+```
+
+---
+
+### `cluster-unit`
+Создаем папку и файл рецепта:
+```sh
+mkdir -p ~/yocto-riscv/meta-cluster/recipes-cluster/unit
+nano ~/yocto-riscv/meta-cluster/recipes-cluster/unit/cluster-unit.bb
+```
+Добавляем код:
+```bitbake
+DESCRIPTION = "Cluster Unit Stub"
+LICENSE = "MIT"
+LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
+
+SRC_URI = "file://unit.sh"
+
+do_install() {
+    install -d ${D}/usr/bin
+    install -m 0755 ${WORKDIR}/unit.sh ${D}/usr/bin/unit
+}
+FILES:${PN} += "/usr/bin/unit"
+```
+
+Создаем заглушку `unit.sh`:
+```sh
+mkdir -p ~/yocto-riscv/meta-cluster/recipes-cluster/unit/files
+nano ~/yocto-riscv/meta-cluster/recipes-cluster/unit/files/unit.sh
+```
+Добавляем:
+```sh
+#!/bin/sh
+echo "Cluster Unit is running"
+```
+Делаем файл исполняемым:
+```sh
+chmod +x ~/yocto-riscv/meta-cluster/recipes-cluster/unit/files/unit.sh
+```
+
+---
+
+## 4. Добавление пакетов в сборку
+Редактируем `local.conf`:
+```sh
+nano ~/yocto-riscv/poky/build/conf/local.conf
+```
+Добавляем:
+```
+IMAGE_INSTALL:append = " cluster-controller cluster-unit"
+```
+
+---
+
+## 5. Сборка образа
+```sh
+bitbake core-image-minimal
+```
+
+---
+
+## 6. Запуск в QEMU и проверка
+```sh
+runqemu qemuriscv64
+```
+Проверяем заглушки:
+```sh
+controller
+unit
+```
+Они должны вывести:
+```
+Cluster Controller is running
+Cluster Unit is running
+```
