Hi Pratik,

Offhand I do not see any issue with the configuration. But I think for 
VM images store, using gfapi may give better performance than compared 
to fuse. CC'in Kritika and Gobinda who have been working on this 
use-case and may be able to guide you.

It would be great if you can suggest me whether I should stick with glusterfs or move to any other technology. Currently I am using Glusterfs with fuse on CentOS for Storing images of Virtual Machine in CloudStack Setup. Majority of workload is of SQL Server & MariaDB database server, and some Web Servers. The issue is of slow booting and slow UI response of VMs and also lot of time outs in SQL server database even on small databases. I have dedicated 10G network for storage in my setup.
