Hello,

could you please check what kind of i/o schedulers are used
when vanilla kernel is booted and when OpenVZ is booted?
It may be obtained via "cat /sys/block/sdb/queue/scheduler".
The same interface can be used while changing that value.

"echo "SOMETHING" > /sys/block/sdb/queue/scheduler".

And some additional information (just in case):
from both kernels

- cat /proc/meminfo
- cat /proc/mounts
- tune2fs -l $DEVICE
