[Solved] Virt-manager problem

Hello everyone,a big like for the dev team and commiters, this is a awesome distrib :slight_smile:

I use virt-manager for my vm’s and it was working 2 weeks ago on my old install, i do a fresh install (i check the sha512 for the .iso) . And then, this message occured at the install process of a vm with quemu/kvm :

Cannot complete installation : « internal error: process exited while connecting to monitor: 2018-03-23T10:36:45.590970Z qemu-system-x86_64: can’t apply global Broadwell-noTSX-x86_64-cpu.spec-ctrl=on: Property ‘.spec-ctrl’ not found »

What version of Parrot are you running? ( Parrot Security 3.11 )

What method did you use to install Parrot? (Debian GTK )

Configured to multiboot with other systems? ( No )

Problem bypass with :

-not use the qemu://system connexion

-create a new connexion qemu://session


What kernel are you running on the host?

I think this has to do with the meltdown/spectre patches within the kernel , try “copy host cpu configuration” on virt-manager gui

Sorry for the late response,

Metldown/spectre has nothing to do with my problem.

And the step to resolve this issue is to add user to these groups :


Thanks for the response.
