[one-users] A wishlist for open nebula 4.6?

[Gareth Bult]

Hi Shankhadeep, 

I'm using virtio-scsi by default on all my instances (I need it for TRIM support) .. works fine on 4.3 and 4.4. 
All you need to do is modify /etc/one/vmm_exec/vmm_exec_kvm.conf. 

I use this; 

DISK = [ BUS="scsi", DISCARD="unmap"] 
RAW = "<de vices><video><model type='vga' vram='9216' heads='1' /></video><controller type='scsi' index='0' model='virtio-scsi'> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/></controller></devices>" 

Then use "sd" in DEV_PREFIX in the template .. 

hth 
Gareth.

1. GlusterFS libgfapi support, I was hoping this would be completed for this release, alas I'm stuck with fuse mount another release :) 
2. Support virtio-scsi, this is the future of KVM block IO, its not as fast as virtio-blk but its getting there and it is far more flexible. For example, you don't need to have pci-hotplug support to add another disk, a simple scsi bus scan will work. Also support for faster block io access will be in place soon like tcm-vhost in most distros.
