it's quite easy:

[root@dhcp0-95 ~]# cat /proc/vz/vestat

- column 1 "VEID": VE id Smile

- column 2 "user", 3 "nice", 4 "system", 5 "uptime" - corresponding std user/nice/system/uptime values in jiffies to standalone linux /proc/stat. Note, there is no "idle" time here, since it can't be calculated this way.

the next group comes in cycles units:

- column 6 "idle" - idle time, 7 "strv" - not used, 8 "uptime" - uptime in cycles, 9 "used" - used time by VE across all CPUs in cycles

the next group is scheduling latency statistics in cycles:
- column 10 "maxlat" - max latency in cycles meaning how long VE process has to wait before it actually got CPU time.
- column 11/12 "totlat/numsched", i.e. divide 11 on 12 to get average scheduling latency.

you can also read:

[root@dhcp0-95 ~]# cat /proc/vz/stats
Version: 2.6
cycles_per_jiffy: 1860831
jiffies_per_second: 1000

to understand how many cycles and jiffies are per second.
