I'm using Debian 6 (stable, Linux 2.6.32) with vzctl version 3.0.24
Look at error message and same memory results in the container.
$ getconf PAGE_SIZE
4096
$ vzctl create 777 --ostemplate debian-6.0-x86
Creating container private area (debian-6.0-x86)
Performing postcreate actions
Container private area was created
$ vzctl set 777 --physpages 0:256m --swappages 0:512m --setmode restart --save
Saved parameters for CT 777
$ vzlist --all --output ctid,physpages.b,physpages.l,swappages.b,swappages.l
CTID PHYSP.B PHYSP.L SWAPP.B SWAPP.L
777 0 65536 0 131072
$ vzctl start 777
Starting container ...

Setting CPU units: 1000

$ vzctl exec 777 "free -m"

$ vzcfgvalidate -r /etc/vz/conf/777.conf
Error: limit should be = 2147483647 for physpages (currently, 65536)
set to 2147483647
Validation completed: success
$ vzctl stop 777

$ vzctl start 777

$ vzlist --all --output ctid,physpages.b,physpages.l,swappages.b,swappages.l
CTID PHYSP.B PHYSP.L SWAPP.B SWAPP.L
777 0 2147483647 0 0
$ vzctl exec 777 "free -m"
total used free shared buffers cached
Mem: 256 10 245 0 0 0
-/+ buffers/cache: 10 245
Swap: 512 0 512
$ vzcfgvalidate -r /etc/vz/conf/777.conf
Validation completed: success
I don't understand why physpages.l should be 2147483647 instead of 65536, and why once the value is "corrected", RAM and Swap for the container still have the initial values set.
