HP 9000 Containers A.03.01 on HP Integrity Server Administrator Guide HP-UX 11i v3 (5900-3112, June 2013)

11 Limitations of HP 9000 Containers
The following sections explain the limitations of HP 9000 Containers.
11.1 Application limitations
Does not support kernel intrusive applications and applications that use privileged instructions
Applications that are kernel intrusive and that use privileged instructions do not work inside an HP
9000 container. This includes device drivers and applications that read or write /dev/kmem, or
use DLKMs.
Does not support system management applications
Management utilities such as SAM, HP SMH, or applications such as HP Openview agents, and
HP SG that perform tasks related to system management or monitoring are not supported inside
an HP 9000 container. You can run these applications in the global container.
Does not support system resource monitoring applications
Performance agents and applications that perform disk, memory, or CPU monitoring are not
supported inside an HP 9000 container. You can run these applications in the global container.
Does not support non-manageability applications in the global container
Running applications in the global container is not supported, except for those related to system
management or monitoring.
Does not support DHCP server, DNS server, NFS server, X server, and IP routing
DHCP, DNS, NFS, and X servers are currently not supported inside an HP 9000 container. Using
the container as a router is also not supported.
Other limitations

For more information about other known emulation issues with common application stacks, see
Section 12.6 (page 80).
11.2 Setup limitations
Does not support DHCP IP address
HP 9000 Containers supports only static IP addresses for containers. Using DHCP as container IP
address is currently not supported.
Does not support large base page size
Applications running in an HP 9000 container on an HP-UX 11i v3 system, where kernel tunable
parameter base_pagesize is configured to a non-default value, might experience correctness
issues with symptoms such as application hangs and aborts. The workaround is to set the value of
kernel parameter base_pagesize to 4 KB (which is default).
Does not support large PID, UID, host name with legacy containers
Legacy (earlier than HP-UX 11i v3) containers might not have the necessary user-space components
to support large values of PID, UID, GID, host name, and node name. Therefore, such large values
cannot be supported with HP 9000 containers built from such environments. In particular, you must
set the value of process_id_max parameter on the HP-UX 11i v3 host system to 30000 even
though the kernel can support larger values for this parameter.
Additional limitations specific to HP 9000 classic containers
Additional limitations of HP 9000 classic containers are as follows:
