From 530a0963184e57e71a5b538e9161f115df533e96 Mon Sep 17 00:00:00 2001 From: Julia Suvorova Date: Wed, 26 Feb 2020 18:46:07 +0100 Subject: pcie_root_port: Add hotplug disabling option MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make hot-plug/hot-unplug on PCIe Root Ports optional to allow libvirt manage it and restrict unplug for the whole machine. This is going to prevent user-initiated unplug in guests (Windows mostly). Hotplug is enabled by default. Usage: -device pcie-root-port,hotplug=off,... If you want to disable hot-unplug on some downstream ports of one switch, disable hot-unplug on PCIe Root Port connected to the upstream port as well as on the selected downstream ports.
