Mounting ISO file to an Azure VM with CentOS v6.3

Hi, Not sure whether this is the right forum to post my query. If not, kindly redirect me to the correct forum.

I have created a VM with CentOS version 6.3 operating system provided by OpenLogic.

Now we need to mount an ISO file to this VM and need to boot from the same. Is this is possible in Azure ?

Looking forward for a valuable response,

Thanks and Regards,
