You’ll want to go to normal unreserved DHCP. Each VDI VM needs its own IP.
Even more: Each VM needs its own IP address and each access point needs one too.
If you use 10 VMs on a single host, then you need 21 IP addresses when each VM is in use:
1 IP address for the host
1 IP address per VM = 10 IP addresses
1 IP address per end point = 10 address
