I\'d like to download a VM image to my local machine, so I can use it locally and upload it to another credential of Azure. I know that there is blob URL but wget didn\'t help t
The reason you're getting this error is because the blob is in a private blob container. You could do a few things:
If you wish to migrate blob to another storage account and you wish to use a tool, may I suggest you use Cloud Storage Studio (http://www.cerebrata.com/Products/CloudStorageStudio). Using this tool you can also download the VHD. Also do take a look at this blog post as well: http://www.biztalkgurus.com/biztalk_server/biztalk_blogs/b/biztalk/archive/2012/09/26/windows-azure-virtual-hard-disk-blob-storage-cross-account-copy-lease-break-and-management-tool.aspx.
Hope this helps.
