Hello and welcome. In this demonstration, I will show you how you can work with dedicated virtual machine host. We know that dedicated virtual machine host feature gives us the ability to run compute virtual machine instances on dedicated servers that are a single tenant and not shared with other customers. So let's go ahead and see a demonstration on how you can create a dedicated virtual machine host. So as you can see, I'm currently in the OCI console logged in as the computer admin. So click on the hamburger menu, click on compute, under compute click on dedicated virtual machine hosts. So before you can work with dedicated virtual machine hosts, you need to add the policy statements in the identity and access management service. So these are the policies that you need to add. So if you want the users to manage compute dedicated virtual machine hosts, so these are the two policies that you require. Allow group computeadmins to manage dedicated-vm-hosts in compartment- archassociate compartment. And then allow group computeradmins to manage instances in this particular compartment. In case you want the users to launch compute instances on dedicated VM hosts, then you basically require these policies. Allow group computeradmins to use dedicated-vm- hosts in this particular compartment. So I have gone ahead and added these policies in the identity and access management service. So now let me create a dedicated virtual machine host. So click on create, this is where you provide the name, DVH-demo. I can select the compartment. I have to select an availability domain. And as you can see here these are the dedicated host shapes. And this is the OCPU information. And if you click on this particular arrow, so you can see the compatible virtual machine shapes with this particular dedicated virtual machine host. So if you select DVH.DenseIO2.52, so you'll be able to launch the virtual machine of these shapes. So the point here is when you create a dedicated virtual machine host, you select a shape for the host. And then this particular shape is going to determine how much capacity is available and what type of instances can be launched on that particular host. For the purposes of this demonstration, I will go ahead and launch DVH.Standard2.52. That has got 52 OCPUs. So let me click on create. As you can see the dedicated virtual machine host is now creating. Now you can see that the DVH-demo is active, so it is successfully created. So under the dedicated virtual machine host information, you can see the availability domain, the total OCPUs, the remaining OCPUs, the total memory, and the remaining memory. Now, let me show you one thing. While creating this dedicated virtual machine host, remember this was the shape that we created, DVH.Standard.2.52. And you can see the number of OCPUs was 52. When you look at the dedicated virtual machine host information, the total OCPs are 48. Why is there a difference between the number listed for build OCPUs compared to the available OCPUs? This is because some OCPUs in this case 4 OCPUs are reserved for virtual machine management and therefore you are able to see 48 available OCPUs. Now with respect to building, you have built for this dedicated virtual machine host as soon as you created. But you have not built for any of the individual virtual machine instances that you place on it. But keep in mind you will still build for any image licensing costs. Now the next part in this demonstration is how do you place instances on a dedicated virtual machine host? So for that you have two options. The first option is you can go to the instances, click on create instance. I'm okay with the default name. You can select the compartment, and under placement you click on show advanced options. So under capacity type, instead of on-demand capacity, now you have to select dedicated host. So once you select dedicated host you should be able to select the one that we created. And when you select you also see the remaining OCPUs and the remaining memory. And depending on the shape that you select, you can basically change the shape. So remember we discussed that depending on the virtual machine host that we were selecting, that is going to support specific VM shapes. So we can see that if you click here, the selected virtual machine host is not compatible with this shape. So if I scroll down, yeah. So these are the ones, VM.Standard2.1, 2.2, 2.4, 2.8, 2.16, and 2.24. So these are the virtual machine shapes that are supported with the dedicated virtual machine host that we have created. So let me go ahead and select VM.Standard2.4. Let me click on select the shape. Rest, everything remains the same. Let me click on create. So in the meantime, this instance is getting created. If I return back to the dedicated virtual machine host, now you can see that the total OCPUs were 48. The remaining OCPUs are 44, the total memory was 736, and the remaining memory is 676. Why? Because this particular instance took 4 OCPUs and 60 GB memory. And hence you are able to see these particular values. The other option to create instances on a dedicated virtual machine host is to go to the hosted instances under resources, right? So as you can see there is already one instance that we have created. So you can just click on create instance and that is going to take you to the same page from where we created the compute instance. So this marks the end of this demonstration where we looked at how we can create a dedicated virtual machine host and how we can place an instance on that particular host. I hope you found this demo useful, thanks for watching.
