@Misra, Saurav - I see that you have raised the same issue on other post here : https://learn.microsoft.com/en-us/answers/questions/624007/index.html
Reiterating the same info here for broader audience :
For creating a VM, the image has to be locally available in that region where you plan to spin off the VM or it should be kept in a Image Gallery replicated in all the regions so that the VM can be spinned off in any region. The above issue happens when the image is in different region and the VM is created in another region.
Hope that helps.
