Overriding default units
You can set parameter units explicitly 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 (totals to almost 4 Mb on x86)
# vzctl set --tcprcvbuf 1000p
