Hello,
Is there LVM support for the ATLAS@HOME project? I am using Fedora 25 x86_64. I would prefer to use LVM over VirtualBox. Is there LVM support or any plans to add support?

Thanks.

Hello,

LVM is as far as I know "Logical Volume Manager" used to control/create/resize volumes, partitions rather than virtualization software like Virtualbox that runs virtual machines hosting containers, VDI/VHD/VMDK.

Just a thought and please correct me if I am wrong :-)

yes.

probably he is talking about KVM (kernel based virtual machine). There is no support for this kind of "virtualisation" at the moment.
But if you are on Linux there will be a native app in the future (there is one right now but it is for CentOS 7 and SLC6 only) so you wont need KVM or Virtualbox.

...and unfortunately, there won't be support for KVM ever.
This was discussed before.

Main reason for BOINC (in general) relying on VBox instead of more performant Hypervisors, was because they hoped it would simplify things for developers and users.
VBox was available for Windows and Linux and understandable for all kind of users. At least in theory, cuz imho, this all wasn't so simple as they thought.
Message boards were/are full of VBoxVersionXYZdoesn'tworkwith or plzdon'tupdate or thissimplydoesn'twork.
To make things worse, wrapper development is the most difficult part of it all (means, the communication between BOINC at the hypervisor with the VM inside), at least this was told to me.

Guess, things were the same for lhcathome, which seems to be a little funny, because especially CERN should have good experiences with the distributions of complete VMs (like the Cern VM). If they would distribute properly configured VMs for all kind of hypervisors, this would really simplify things for all.
Bandwith for the first download shouldn't be that problem. In times, when people are willing to spend their bandwith for Windows 10, no one can really complain about a seldom download of an ~ 10 GB image.

Hopefully one of the cross-platform containers will prove to be useful.
