**It is not possible to exceed the server's max_memory when increasing RAM on KVM Compute resources. Detailed info about RAM resize without reboot and hot-migrate abilities per template is available at:

*** At least one IPv4 address must be allocated to a virtual server's primary network interface, as some applications do not support IPv6.
