 200 denotes the number of pages to be shown in the /proc/meminfo output.
In our case the /proc/meminfo output inside Container 101 may look like the following:
# pctl exec 101 cat /proc/meminfo
MemTotal: 8000 kB
MemFree: 5140 kB
LowTotal: 8000 kB
LowFree: 5140 kB
Buffers: 0 kB
Cached: 0 kB
SwapCached: 0 kB
HighTotal: 0 kB
HighFree: 0 kB
...
When working in this mode, keep in mind the following:
 The specified amount of memory (in our case it is 8000 Kb) is always shown in the
MemTotal and LowTotal fields of the cat /proc/meminfo output.
 The values in the MemFree and LowFree fields are calculated automatically by the
system.
 All the other fields in the command output have the values set to 0.
 To set the output of /proc/meminfo inside Container 101 to the 'virtualized in
privvmpages' mode, execute the following command:
# pctl set 101 --meminfo privvmpages:3 --save
The amount of memory that will be displayed by running the cat /proc/meminfo
command inside Container 101 is calculated using the following formulas:
 Privvmpages_Value * 3 * 4Kb if Container 101 is running a 32-bit operating
system (OS) or an OS for x86-64 processors and
 Privvmpages_Value * 3 * 16Kb if Container 101 is running an OS for IA-64
processors
where Privvmpages_Value denotes the value of the PRIVVMPAGES parameter set in
the Container configuration file and 3 is an arbitrary integer coefficient which you can
modify to increase/decrease the amount of memory in the /proc/meminfo output.
Assuming that the privvmpages parameter for Container 101 is set to 10000, your output
may look as follows:
# pctl exec 101 cat /proc/meminfo
MemTotal: 120000 kB
MemFree: 78248 kB
LowTotal: 120000 kB
LowFree: 78248 kB
Buffers: 0 kB
Cached: 0 kB
SwapCached: 0 kB
HighTotal: 0 kB
HighFree: 0 kB
...
As can be seen from the example above, the displayed records comply with the same rules
as the records in the 'virtualized in pages' mode.
 To revert the output of /proc/meminfo to the default mode, execute the following
command:
# pctl set 101 --meminfo none --save
