How can I test hd performance on an OpenVZ container?

Question

CentOS 5.x | VPS | OpenVZ

I'm trying out a vps that uses OpenVZ and am not sure what command to type to measure disk read performance. I thought hdparm would work but I get the following:

[root@echo dev]# hdparm -t /dev/simfs
/dev/simfs: Permission denied

Yet I don't see any other file systems to check...

[root@echo dev]# mount
/dev/simfs on / type reiserfs (rw,usrquota,grpquota)
/proc on /proc type proc (rw)
/sys on /sys type sysfs (rw)
none on /dev type tmpfs (rw)
none on /dev/pts type devpts (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

Anything else I can try?

good old bonnie++; not most flashy benchmarking tool but one that gives useful results [ random and sequential reads/writes, i/o per sec ].
