UBC parameter units
User Beancounters have default units which are used when viewing and setting the parameter values. When setting the values for some parameters, you are able to specify different units thereby avoiding the need to do manual conversion of units and making life a little easier!

When using vzctl to set these beancounter parameters, you can override the default units of "pages" by using a valid suffix.

- Primary Parameters
- None
When using vzctl to set these beancounter parameters, you can override the default units of "bytes" by using a valid suffix.
Overriding Default Units
When using vzctl to set beancounter parameters which use "Pages" or "Bytes" as the default units, alternative units may be specified using one of the following suffixes:
Suffix | Alternative Suffix | Units |
---|---|---|
g | G | gigabytes |
m | M | megabytes |
k | K | kilobytes |
p | P | pages |
Examples
The following are some examples to demonstrate the use of different units when specifying the value of a parameter. Where $CTID
is the container ID.
- Set
kmemsize
limit to 512 KB
# vzctl set $CTID --kmemsize 512k
- Set
privvmpages
limit to 256 MB
# vzctl set $CTID --privvmpages 256m
- Set
tcprcvbuf
limit to 1000 pages (totals to almost 4 MB on x86)
# vzctl set $CTID --tcprcvbuf 1000p
