The AF_VSOCK protocol added in Linux 5.6 uses a 32 bit port number.
For NBD we map this to simple URIs[1] like nbd+vsock://CID:PORT (where
CID is a number that acts a bit like a hostname and PORT is a 32 bit
port number). eg: nbd+vsock://1:10/ would be port 10^9 on the
loopback address VM

Actually I miscounted the number of 9's. The limit is 99,999,999
