I have uploaded the .deb > packages to https://github.com/weizhouapache/ubuntu-libvirt-packages Quick update: - on kvm1 (with libvirt 10.0.0-2ubuntu8.9), CPU usage has increased to 7.5% after around 24 hours - on kvm2 (with libvirt 10.6.0-1ubuntu3.3), CPU usage is still 0.6% after around 12 hours GitHub link: https://github.com/apache/cloudstack/discussions/12450#discussioncomment-15515842 ---- This is an automatically sent email for [email protected].
