Subject: [pve-devel] [PATCH qemu-server 1/1] fix #5619: honor link_down setting when hot-plugging nic
Date: Tue, 23 Jul 2024 15:14:09 +0200 [thread overview]
Message-ID: <20240723131409.132792-1-s.hanreich@proxmox.com> (raw)
When detaching and attaching the network device on update, the
link_down setting is not considered and the network device always gets
attached to the guest - even if link_down is set.
Fixes: 3f14f206 ("nic online bridge/vlan change: link disconnect/reconnect")
