Suggestions for KVM manager?

I have a home server based on Ubuntu18.04 and KVM. Currently, I manage it from a Macintosh laptop using libvirt (virt-manager) via VNC. I'm wondering if there are better solutions for this. For example, I looked at Kimchi (web-based) and it seemed excellent, but I could not get it to run correctly on Ubuntu (it appears to want CentOS or similar).

Any other (free and open-source) useful management utilities I could install?

Thanks
Eric
