UBC parameter units

UBC default units

1. entries which name has word 'page' are measured in memory pages (4kb on x86 and x86-64, 16kb for IA64). These are privvmpages, oomguarpages and others.
2. entries with names like 'num*' are measured in items. i.e. numproc - number of processes, numiptent - number of iptables entries.
3. other entries like kmemsize, tcprcvbuf/tcpsndbuf are measured in bytes

Overriding default units

You can set parameter units implicitly when appropriate, for example:

• Set kmemsize limit to 512 Kb

# vzctl set --kmemsize 512k

• Set privvmpages limit to 256 Mb

# vzctl set --privvmpages 256m

• Set tcprcvbuf limit to 1000 pages (4 Mb on x86)

# vzctl set --tcprcvbuf 1000p
