From 156dc7b1740d9f71baf4aef277d7f812f1a784ba Mon Sep 17 00:00:00 2001 From: Amador Pahim Date: Mon, 22 Jan 2018 21:50:33 +0100 Subject: [PATCH] qemu.py: don't launch again before shutdown() If a VM is launched, files are created and a cleanup is required before a new launch. This cleanup is executed by shutdown(), so shutdown() must be called even if the VM is manually terminated (i.e. using kill). This patch creates a control to make sure launch() will not be executed again if shutdown() is not called after the previous launch().
