I've been having intermittent network issues on my Host - they go away when I stop and disable libvirtd and then reboot. They do not go away if I just stop libvirtd and don't reboot.

After an update (kernel, libvirt afaik) and a reboot, pci-passthrough stopped working. Intel IOMMU is enabled (can see that from the dmesg output). All i get on the console when i try to start
