Hi,
I have some trouble with the Virtual Machine Manager that somehow decided not to launch VMs anymore.
When I power on my virtual machine (it’s dubbed Win10) from the Virtual Machine Manager GUI, I have the following error:
Error starting domain: internal error: process exited while connecting to monitor
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper

Here is the relevant part of /var/log/libvirt/qemu/Win10.log

2022-08-19 18:50:23.983+0000: shutting down, reason=failed
but it does not seem to be truly helpful
I read somewhere this had something to do with new groups related to libvirt, so I made the following changes to /etc/libvirt/qemu.conf
# The user for QEMU processes run by the system instance. It can be
# specified as a user name or as a user id. The qemu driver will try to
# parse this value first as a name and then, if the name doesn't exist,
# as a user id.
#
# Since a sequence of digits is a valid user name, a leading plus sign
# can be used to ensure that a user id will not be interpreted as a user
# name.
#
# Some examples of valid values are:
#
# user = "qemu" # A user named "qemu"
# user = "+0" # Super user (uid=0)
# user = "100" # A user named "100" or a user with uid=100
#
user = "root"
# The group for QEMU processes run by the system instance. It can be
# specified in a similar way to user.
group = "libvirt-qemu"
and I added my user to libvirt-qemu and checked back with groups that my user was in it
But it still does not work with the same error as before
I saw there was a new version of libvirt so I updated everything but I still have the bug with version 1:8.6.0.2 (and I even tried with the default and the new /etc/libvirt/qemu.conf but the new version fails with both)
Do you have any idea of what I else could try?
