Hi,
 

- I can create VMs successfully but very very slow performance.

Are you using virtio drivers? I also recommend playing with the
'cache' parameter. How well does it perform compared with I/O
operations in the hypervisor? Is the storage the problem here or the
Virtualization layer?

I am using KVM hypervisor. I also used Chachefilesd but while launching vms it takes long time. Also poor writing speed inside the vm.



- Also when I created VM on node1 and try to migrate it other vm it
does not work as logical volume of that VM on node2 is inactive.

have you set up cLVMd? I think for your setup the best approach is:
http://docs.opennebula.org/4.10/administration/storage/fs_lvm_ds.html

Or something like GFS2.

No I did not configure CLVMd or GFS as it needs fencing device.

Hi,
I am setting up OpenNebula on 2 nodes and 1 storage on 1Gb Network.
- installed Nexenta Community Version on Storage and created iSCSI
LUN.
- Access those LUNs on both nodes and created Volume Group on it.
- Configured LVM Block Datastore in OpenNebula.

What do you recommend for this type of setup for Shared Storage
LVM, NFS? Please note that I need to use 1GbE copper due to budget
limitations.
