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. > 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 If you want to try developing libvirtd you should start by enabling debug logging.
