I have a 64bit Centos VPS hosted on openvz. I could install zimbra without any error. But when I try to start/stop zimbra using zmcontrol start, Getting a JVM error below,

Could not create the Java virtual machine.
mkdir : No such file or directory at /opt/zimbra/bin/zmcontrol line 35

What would be the reason? Has zimbra supports openvz?. Is this related with privvmpages size?
Please help me.
