KMV disable hotplug

[Matthew Ritchie <ri...@gmail.com>]

Hi all,

I am using KVM with Cloudstack 4.17.2.

When a windows vm is created the virtIO devices appear at the taskbar as
available to unplug.

Is there a way to disable hotplug functionality or another way to restrict
hot-unplugging?

regards
Mat

It's a known Windows issue, if we can call it that.
Hotplug is a very valid and useful feature, but perhaps showing it so 
easily in the taskbar can confuse certain users.
It can be "fixed" with regedit.

Random search results (it's about the same issue on VMWare):

Hi Mat,

This sounds like an OS issue, I think you can explore if there's something in your template you can configure to disable users from unplugging.

Since 4.17 is old now, there's perhaps something in the extraconfig you can pass but you'll need to investigate if libvirt/kvm has any confgiuration to disable hot-plugin feature  and then use extraconfig [1]. That said, I wouldn't advise you to explore this, just explore if you can the OS.
