MHVTL on Ubuntu 11.04 with ISCSI

Created: 13 Jun 2011 | 2 comments

New version of virtual machine which can be used to testing and training.

MHVTL is a open source VTL project developed by Symantec employee - Mark Harvey. (

I added ISCSI functionality by integrating MHVTL with STGT (


Ubuntu Server 11.04 x64 (without kernel patching and recompilation)
VMware Virtual Machine (Fusion, Workstation)

IP: (/etc/sysconfig/network)
login: user1
pass: user1
root - "sudo su -"

300 GB btrfs filesystem on lvm (lvm and btrfs can be easily resized)

mhvtl 0.18-16
stgt 1.0.17 (ISCSI targets)

1x L700
4x LTO4 (compression factor=1)
60x LTO4 tape (5GB)


ISCSI STGT targets are created automatically after mhvtl start.

start/stop commands:
/etc/init.d/start-mhvtl-iscsi start
/etc/init.d/start-mhvtl-iscsi stop

BTRFS filesystem has snapshot functionality so we can create snapshots of mhvtl setting and tape data, for example:
btrfs subvolume snapshot  /opt/mhvtl /opt/snapshot/mhvtl_12_06_2001
btrfs subvolume snapshot  /opt/etc /opt/snapshot/etc_12_06_2001
(/etc/mhvtl linked to /opt/etc/mhvtl)


Backup and restore tested with NetBackup 7.0.1 installed on Windows 2008 x64 R2

Virtual machine can be imported into VMware ESX infrastructure using VMware Converter.

Unfortunately all Links are down!

Could you please provide some new link? I would like to do some testing on Symantec Backup Exec with media changer support.

Thanks in advance!

I think you might want to go right to the source and get the latest version (as I type this, it's mhvtl-2012-01-21.tgz / mhvtl-1.2-1)

Start here:
