How to add a real HDD to a OMV virtual machine?

openvault · 31. März 2015

Hi all,

I've install OMV onto a virtual machine using Virtual Box. I want to access from this OMV to the real hard drives connected to the machine, but I only see option for adding virtual disks.

The aim is having full access to those disks and handle them just like I would in the real machine, having the possibility of creating even a Raid if I want.

Anyone knows how to do this?

Regards and thanks in advance

Hi,

Yes I have done that on my local machine. I have windows 7 as a host, virtualbox installed on it, and OMV as a guest.

You have to follow the instruction there https://www.virtualbox.org/manual/ch09.html#rawdisk

I personnally implemented what is stated in 9.9.1.1.

I did it twice for my two 2TB hard drives, and then, once recognized by OMV, I just used the RAID management service of OMV to create a RAID1 partition. Easy.

Regards,

I run OMV as the host and then virtualbox on that host and then a few other OMV instances for testing and other things. Can I use this to access the host OMV RAID arrays directly from the VM's?

In my opinion, yes, no reason it would not work.

Follow the same instruction pasted above, and just connect to your host in SSH to correctly apply the command line.

It depends on the hardware you are using, to do this, you need your CPU/motherboard/HBA supporting VT-d so that you can have a device being "passthrough" to the guest OS. Otherwise you will always see a virtual disk only.
