-Each GPU VM can only use GPUs from a single node, and GPU VMs are not automatically load balanced. For example, you have 4 nodes and 2 GPUs on each node, and you create 4 VMs with 1 GPU for each VM. Each VM can exist on a different node. If that happens, any single node will only have 1 available GPU left. From the portal, you can see that there are 4 GPUs available. However, if you try to create a VM with 2 GPUs, it fails with insufficient GPU capacity, because no single node has 2 GPUs available. The solution is to create the VMs with 2 GPUs first.

-Azure Stack Hub supports GPU partitioning for the AMD MI25. With GPU partitioning, you can increase the density of virtual machines using a virtual GPU instance. You can change the partition size to meet specific workload requirements. By default, Azure Stack Hub uses the largest partition size (1/8) to provide the highest possible density with a 2 GB frame buffer. This is useful for workloads that require accelerated graphics applications and virtual desktops.
