Differences between vPars and HP Integrity Virtual Machine
vPars segments a system using dedicated CPUs and I/O hardware per partition; these are
exclusively under the control of the vPar’s booted kernel. Integrity Virtual Machine allows sub-
CPU granularity and shared I/O on the same I/O hardware among kernels known as guests.
A vPar uses dedicated CPUs and LBAs. PCI-Interfaces attached to the same LBA can not be
shared.
vPars has minimum overhead, while Integrity VM maximizes resource utilization.
Supported Systems and Requirements for vPars
 vPars versions A.03.XX and earlier are supported only on HP-UX 11i v1 (11.11).
 vPars version A.04.xx is supported only on HP-UX 11i v2 (11.23).
 vPars version A.05.xx is supported only on HP-UX 11i v3 (11.31).
Versions A.05.xx and earlier do not allow to mix HP-UX 11i v1, 11i v2 and 11i v3 on different
vPars on a server.
