Yes, it would. If you want to export all of your VMs
all at once and
have no plans to rename them or alter them whatsoever, why not just back
up the entire export storage domain and attach to the new DC/Cluster?
WRT to 3. I agree that is a clunky process to create a portable VM. I
would like to create a tool that allows you to pick a VM from available
exported ones and subsequently wrap it up into a .tgz. Shouldn't be too
hard.
apart of Vered's simpler solution, a small note that:
1. engine-image-uploader can handle uploading the same image more than
once and generating uuid's
Correct.
2. however, i think this capability is deprecated, since engine has
recently added support to import a VM which UUID is already imported,
allowing to create a new VM from the imported one.
Correct.
