vzsplit(8) Containers vzsplit(8)NAME
vzsplit - generate a sample container configuration file
SYNOPSIS
vzsplit [-n numve] [-f conf_name] [-s swapsize] [-v yes|no]
DESCRIPTION
The vzsplit utility is used to split the Hardware Node into equal parts. It generates a full set of system resource control parameters for
the given number of containers. The values are calculated from the total physical memory of the Hardware Node the utility runs on, and the
number of containers the Hardware Node shall be able to run even if the given number of containers consume all the resources available.
Without any option given, vzsplit prompts for the desired number of containers and outputs the resulting resource control parameters to
stdout.
If there are not enough system resources to run the specified number of containers, an appropriate message is shown and the sample configu-
ration file is not generated.
OPTIONS -n numve
Specify the number of containers.
-f conf_name
Specify the configuration sample name to write configuration to, instead of standard output. The file created will be named
/etc/vz/conf/ve-conf_name.conf-sample.
-s swapsize
Specify the swap size in Kbytes. If this option is not given, the swap size is read from /proc/meminfo.
-v yes|no
Whether to generate VSwap enabled configuration. Default is auto-detect by checking if running kernel is VSwap capable; this option
overrides auto-detection.
EXIT STATUS
vzsplit returns 0 upon a successful execution. If anything goes wrong, it returns 1.

ImVirt - detects several virtualizations
SYNOPSIS
use ImVirt;
print imv_get(IMV_PROB_DEFAULT, imv_detect()),"
";
DESCRIPTION
The "ImVirt" package tries to detect if it is run in a virtualization container. At least the following container should be detected:
ARAnyM
KVM
lguest
LXC
OpenVZ
QEMU
UML
VirtualBox
Virtual PC/Server
VMware
Xen
DETECTION HEURISTIC
The detection is based on a heuristic - you should not trust the result at all.
ImVirt probes for different well-known characteristics of different virtualization containers. Any characteristics found or not found are
weighted by their significance.
The result of the heuristic is a weighted tree. The leaves are the (not) detected containers.
FUNCTIONS
The following functions should be used to retrieve the detected virtualization containers:
imv_get($prob) Returns exactly one string describing the detected container. If the detected container has a smaller match probability than
$prob the string 'Unknown' is returned.
imv_get_all() Returns a hash any positive detected containers as keys and their corresponding match probability as value.
imv_get_pos_results() Returns a list of all possible results which might be returned by all detection modules. The list entries might be
appended by some additional data like version numbers etc.

Hi,
Can anybody please help. I am running sco unix 5.0.6 on a Dell Power Edge 2400 . I have two raided mirror containers (using percraid) one 8GB the other 68GB. I have installed the sco unix os onto the 8GB container and I am now trying to create a 68GB filesystem using the 68GB raid container.... (1 Reply)

Hi guys.
Quick question for some hopefully ;-)
When using resource capping (for CPU in this case). If a container is restricted to use a single CPU/core, are the other containers intelligent enough to know that they have fewer CPU's available to them?
My question relates to a T2000 which... (7 Replies)
Hello Friends/AIXgurus,
When you have time, could you please look into below. We're planning to migrate AIX LPARs on to new Hardware.
Requirement: Migrate AIX LPARs from POWER 6 to POWER 8 Hardware (*everything should run as is after the transition)
Below is our thought process. Ours... (5 Replies)
Hi guys, I am confused about how containers work in Linux, especially how chrooting works and about how /proc filesystems are mounted.
So please feel to migrate this question to another forum if this is not the right one.
Now, to business.
Okay Dockers can be confusing to the uninitiated... (10 Replies)
