Morning, all.

 

I recently upgraded the MB/CPU in my Unraid 6 from a Core2 Duo to AMD-FX2 (from 2 cores to 8).  I also upgraded to Unraid6 from 4/5 back when 6 came out (this may be pertinent).  Current version is 6.3.5.  Now, since the new hardware supports virtualization, I have it enabled in the BIOS to allow for the VM capabilities of Unraid.  However, when I navigate to the VM manager to set it up, I get and alert that it can't find /mnt/cache/<whatever>.  What needs to be done to correct this?  Is this due to the fact that I upgraded from 4 through 5 to 6 with a system that had no virtualization capabilities?

 

Additionally, I have a virtualbox VM that I'd like to migrate over from another system.  It is currently a fixed disk (500GB) VM, and I would like to transition it to standard (non-fixed size) prior to.  Do I need to run VBoxManage to change from fixed to standard, then run the qcow2 command to convert from vdi to raw?

Hi Solnoid,

 

Do you not have a cache disk assigned in your system?  I would highly advise doing so to use VMs because otherwise performance will be highly inhibited.  If you absolutely must run your VMs without a cache disk present, you can configure your system share under the Shares page to not use the cache disk.

 

As far as migrating an existing VM, I'm not sure about what you have to inside your VM on VirtualBox before you convert (refer to Virtualbox documentation on that), but for converting the vdisk format, this openstack documentation applies the same to unRAID:  https://docs.openstack.org/image-guide/convert-images.html

 

All the best,

Jon
