[libvirt] Running libvirtd out of source directory connection reset error
Hi all, I'm getting started with hacking around with libvirt and am trying to familiarize myself with launching and running an instance of libvirtd I built from source on Centos 7.6. Following the instructions from https://libvirt.org/compiling.html to launch my built versions of libvirtd and virsh, I get the following error with no other context when trying to start a domain using "virsh start mydomain": error: Cannot recv data: Connection reset by peer Despite this error, I am able to run commands list virsh list. Are there additional parameters needed to launch libvirtd or additional services I need to start up alongside it? Thanks, Peter

Launching libvirt manually on distros with Selinux will not work properly because the process will not have the correct label. The most forward way to launch a custom libvirtd with proper label is to build RPMs (make rpm) and install those. For testing purposes it's also an option to switch selinux to permissive but that will e.g. not allow you to test selinux related changes. Also this is not a good idea to run in anything but development environment.

If you want to try developing libvirtd you should start by enabling debug logging. That might also add some context here.
Despite this error, I am able to run commands list virsh list.
You probably won't be able to start VMs.
Are there additional parameters needed to launch libvirtd or additional services I need to start up alongside it?
You need at least virtlogd.
Peter, Thank you for detailed suggestions! Setting SELinux to permissive did the trick and I will proceed down that path until I'm ready to replace the system libvirt RPMs with my own as you suggested. -Peter On Fri, May 10, 2019 at 3:07 AM Peter Krempa <pkrempa@redhat.com> wrote:
