Enabling of HT on HPVM host machine [lcpu_attr]

[Team_of_5]

Hi,

Whether we can enable HT on HPVM host where host is with HPUX11v3 and guest are HPUX11v2. Will there any issues in enabling HT [lcpu_attr=1] on the  host server.

Also if we are enable HT on host, whether we can allocate the additional logical processors to guest machine as vCPUs or not?

Current Setup:

HPVM Version : B.04.30.00

Total number of CPU in host : 8

Number of Guest : 4

vCPUs: 2 /guest

CPU Entitlement : 10.0%,70.0%,10.0%,10.0%

You must ensure Hyperthreading is disabled before implementing g HP Integrity Virtual Machines on an Integrity server.

Enabling HT on HPVM host won't give you any additional resources, it's also not supported to have HT enabled and HPVM installation disables HT via lcpu_attr=0.
