as far as I understand in order to user xml format for the driver it 
needs to be specified in oned.conf. I did it as below:
#-------------------------------------------------------------------------------
#  OpenVZ Virtualization Driver Manager Configuration
#-------------------------------------------------------------------------------
VM_MAD = [
     name  = "vmm_ovz",
     executable = "one_vmm_ssh",
     arguments  = "ovz",
     type  = "xml" ]
#-------------------------------------------------------------------------------


what else is needed on ONE node to be modified to get raw xml file which 
will be sent to remote host?
Right now if I am trying to create VM from file with its description as 
below:

======================================================
ONBOOT="yes"

# UBC parameters (in form of barrier:limit)
MEMORY  = [ KMEMSIZE="14372700:14790164", LOCKEDPAGES="2048:2048", 
PRIVVMPAGES="65536:69632", SHMPAGES="21504:21504", 
PHYSPAGES="0:unlimited", VMGUARPAGES="33792:unlimited", 
OOMGUARPAGES="26112:unlimited" ]

CPU = [ CPUUNITS="1000", CPUS="1" ]

# the disk can be specified as image but it's name has to be similar 
openvz template file name (see example below)
DISK = [ IMAGE  = "centos-5-x86" ]

# Disk quota parameters (in form of softlimit:hardlimit)
DISK  = [ TYPE = "os", DISKSPACE="1048576:1153024", 
DISKINODES="200000:220000", QUOTATIME="0" ]

# swap can be specified as below
DISK = [ TYPE  = swap, SIZE = 1024, READONLY = "no" ]

=====================================================
I get the following error:

It looks like TM driver ( in my case it is ssh TM) is trying to perform 
some VM template checking against source disk image and fails. What 
needs to be fixed?

What vmm driver did you mean saying "vmm driver"? Is it something 
similar to src/vmm/XenDriver.cc  (e.g. src/vmm/OvzDriver.cc)?
The raw xml config should be passed to remote host where the appropriate 
deployment script (e.g. $SCRIPTS_REMOTE_DIR/vmm/ovz/deploy) is invoked, 
shouldn't it?
Or there is an intermediate step(s) before VM deployment config been 
transfered to remote host but after 'onevm create <vm_template>'?

Thanks!
Nikolay.
