Linux VM Import to Azure

Hi there

i need to import an CentOS 6.9 Image to Azure. It is an Software Appliance we recieved from the vendor. I attached it to my Windows10 Hyper-V and convert the vhdx File in an VHD with fix size.

After this i run the Commands in this Link to prepare the VM for Azure

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/create-upload-centos?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json

The i uploaded the VM an create a new VM. The VM starts. SSH seems to be not working. The connect but in the VM is gray.

Over start and Diagnostic i see following Screen

Do you have an idea what this means? What can i do to fix this?

Which other ways i have to import an VM?
