Opened: Apr 05, 2017

Severity: 4-Minor


-- Commands 'getconf _NPROCESSORS_CONF' and 'guishell -c 'select max_vcmp_guests from blade_info'' show different information. -- Command 'tmsh create vcmp guest <guest_name>' fails and reports an error: Could not allocate vCMP guest (<guest_name>) because fragmented resources.


-- vCMP guest GUI page shows 36 cores are available, but only 32 cores are actually available for vCMP guests. -- After installation of 4, 8-core guests, the BIG-IP system should not allow new guest installations. If you try to install a new guest, the system reports an error that does not describe the real issue: Could not allocate vCMP guest (<guest_name>) because fragmented resources.


-- i11000 hardware with 36 cores. -- vCMP guests are utilizing 32 cores of the system (4, 8-core guests are installed). -- Try to install a new guest.


Limit the number of vCMP guests to the number reported by the command: guishell -c 'select max_vcmp_guests from blade_info'
