AndroidエミュレータはHyper-Vに対応しているはず

Android EmulatorはHyper-Vが有効なマシンでは動かない、という話は、今となっては昔の話...のはず。

プライバシーとセキュリティが糞雑魚な情弱御用達コミュニティサイトであるQiitaの「Hyper-VでサクサクAndroidエミュレータを使おう」という記事を読んで、なにも難しいことはなさそうだし、VirtualBoxをやめてHyper-Vに移行してもいいかな、と思った。¹

ところが、試してみたところ、私の環境では、なかなかうまくゆかずハマってしまった。

	# 1. root権限で実行するためsuに
	su
	※suコマンドを実行できないGSIの場合は一旦exitでadb shellを抜けて以下を実行
	adb root
	adb shell

	# 2. 各イメージがあるパスへ移動する (/dev/block/bootdevice/by-name/ の場合もあります)
	cd /dev/block/by-name/

	# 3. バックアップ保存用ディレクトリを作成

	# First let's update all the packages to the latest ones with the following command
	sudo apt update -qq

	# Now we want to install some prerequisite packages which will let us use HTTPS over apt
	sudo apt install apt-transport-https ca-certificates curl software-properties-common -qq

	# After that we will add the GPG key for the official Docker repository to the system
	curl -fsSL https://download.docker.com/linux/ubuntu/gpg \| sudo apt-key add -

	# We will add the Docker repository to our APT sources

	# The workspace_utils.py module includes an iterator wrapper called keep_awake and a context manager
	# called active_session that can be used to maintain an active session during long-running processes.
	# The two functions are equivalent, so use whichever fits better in your code.
	#
	# EXAMPLE 1
	#
	# from workspace_utils import keep_awake
	# for i in keep_awake(range(5)): #anything that happens inside this loop will keep the workspace active
	# # do iteration with lots of work here
