physpages
usage for all VPSs corresponds to the total number
of pages used in the system by all accounted users.

Network-related parameters allow you to set bandwidth management parameters, hostname and
IP addresses that Virtual Private Server can use as well as to indicate those
iptables modules
that can be loaded to the VPS:
HOSTNAME
If this parameter is specified, then vzctl will set the hostname to its value
upon the next VPS start. This parameter can be omitted. In this case, VPS
administrator should configure the hostname manually.
IP_ADDRESS
This is the list of IP addresses, which can be used on VPS network
interfaces. This list is an argument of the VPS start call and it is impossible
to assign IP address from inside the VPS if the address is not in the list. Any
IP address assigned from within VPS will be visible only within the VPS.
NAMESERVER
DNS server IP address for VPS. More than one server may be specified in
space-separated format.
SEARCHDOMAIN
DNS search domains for VPS. More than one domain may be specified.
