Hi,
I wonder if KVM Virtio-blk's new x-data-plane feature support by Cloudmin UI will take place or considered any how? i would like to report I have tested Virtio-blk with x-data-plane = on Host machine Ubuntu 14.04 an ibm x3850 with SSD drives with a great performance. it must be xdefault mode definitely for Virtio block devices. here is a document you may want to see. http://events.linuxfoundation.org/sites/events/files/slides/CloudOpen201...
but the things is i had to edit guest settings file manually to achieve this. result was ok but Cloudmin UI since i had to change kvm startup parameters in a way that causes Cloudmin can not see disk device in list. "if=none" parameter makes it fail to parse kvm parameter line. I'm not a professional Perl programmer. can't tell more.
I would like to help for Cloudmin support for Virtio optimizations if possible more like code contribution.
Sounds like a good idea. I'll file a ticket in the tracker, so Jamie can look into it. Sounds easy enough to support.
Ticket is here: https://www.virtualmin.com/node/35167

So are there any downsides or limitations to enabling x-data-plane=on ? I'm wondering if Cloudmin should just turn it on by default where supported..

Actually, I found some docs at http://blog.vmsplice.net/2013/03/new-in-qemu-14-high-performance-virtio.... that do list downsides :
None of those seem like deal-breakers though.

Well i knew the downsides but as you say they don't seem like deal-breakers. Anyway maybe not on by default. but can be a new option right?
