IP adresses from range not freed after VM move or deletion

Hello,

We have several KVM hosts managed under Cloudmin Pro.

Two of these hosts are located in the same subnet and share the same IP range for VMs.

We got to the point where all IPs were used, and then we moved or deleted some VMs.

Now, when we look at these host's Network Options, Cloudmin reports "IPs : 8 , Used : 5". So we should be able to create 3 VMs.

But when I tried to clone a VM, the procedure failed, Cloudmin claiming that there were no free IPs in the range...

So I think, there's some data somewhere making Cloudmin "think" that those freed IPs are still in use.

Regards,

Miguel.

If you look at the "IP addresses in use" tab on the "IP Addresses" page, what use does it show for the IPs in that range that should be free?

Sorry for the delay...

The IP address, in the "IP adresses in use" tab was indeed shown as "In Use". We were not aware that for load-balancing purpose, this IP was used by another device. I guess Cloudmin looks in arp cache to see wich IPs are in used in it's local network.

So case closed for us.

Cloudmin will ping any IPs that it thinks are free, just to double check .. and will report "in use" if they respond to a ping.
