VE number An identification number of a VE. VE numbers of VEs attached to a VH are consecutive integer values starting at 0. VH name The hostname of a VH, which is a host computer. logical VE number An identification number of a VE in the NQSV request execution. Logical VE numbers are consecutive integer values starting at 0. logical VH number An identification number of a VH in the NQSV request execution.
