Don't want to trigger anyone, but is Cloudmin still developed, or what is wrong? It has been more than a half a year since myself and others asked, and all the threads are blocked/solved due to inactivity... Or simply pushed down by other issues/posts. Did I miss some update or something?
You have been very scarce on info regarding Cloudmin and CentOS 8, and as a reminder the outstanding problems are:
one can hardly adopt a new CentOS8 KVM host, in a CentOS 7 master; it is doable though;
different QEMU versions so commands (for the networking part I think?) are messed up with a CentOS 8 physical host;
didn't try it but I bet there will be problems installing Cloudmin as a master on CentOS 8.x OS;
problems starting automatically CentOS 8 KVM guests on CentOS 7 hosts - it weirdly hangs, and have to manually restart the VM;
does the proper imaging of running CentOS 8 VMs work? On either a CentOS 7 or 8 Cloudmin master? Because it didn't with CentOS 8.1 KVM guest on a Centos 7.7 host.
8.2 is a great OS, fast and stable as hell, I don't know why it seems so much snappier; seems like a waste to deal in legacy when the future is upon you...
