16.15.2. Limitations

The IP Reservation is not supported if active IPs that are found outside the Guest VM CIDR.
Upgrading network offering which causes a change in CIDR (such as upgrading an offering with no

Reservation in the new re-implemeted network.

16.15.3. Best Practices

Apply IP Reservation to the guest network as soon as the network state changes to Implemented. If
you apply reservation soon after the first guest VM is deployed, lesser conflicts occurs while applying
reservation.

5. In CIDR, specify the Guest VM CIDR.
6. Click Apply.
Wait for the update to complete. The Network CIDR and the Reserved IP Range are displayed on
the Details page.
