Azure Dedicated Host gives you more control over the hosts you deployed by giving you the option to restart any host. When undergoing a restart, the host and its associated VMs will restart while staying on the same underlying physical hardware.
With this new capability, now generally available, you can take troubleshooting steps at the host level. This feature is currently available only in Azure public cloud and we will soon be launching this feature in sovereign clouds as well.
