libvirt users - Apr 2018 - Re: Disable guest discovery in virt-manager

Hi all,
on CentOS7 / RHEL7 launching virt-manager causes a "discovery process"
of the various configured VMs.

This discovery is executed by inspection and overlayed disk files and it 
create a very short lived guest-xxxzzzyyy virtual machine. The end 
result is a pretty icon to the left of the virtual machine entry (ie: 
CentOS icon for a CentOS VM) and the list of installad packages inside 
the virtual disk.

That said, I would like to disable such behavior. How can I do that?
Thanks.

Hi,

The option to enable/disable this feature was implemented recently
in upstream [1].  In order to get it into CentOS/RHEL you would have
to create a BUG for it.

As a workaround you can uninstall python-libguestfs package which is
used by virt-manager to run the introspection.  If that package is
missing importing guestfs in the python code fails and the feature
is disabled.
