How can i add remotefx 3d video adapter to vm with openstack command

edit

First of all you have to make sure you use the compute hyperv driver. You can check this by looking in c:\ProgramFiles (x86)\CloudbaseSolutions\Openstack\Nova\etc\nova.conf and see if compute_driver = hyperv.nova.driver.HyperVDriver

In order to use RemoteFX you have to create a new flavor in Openstack with the following extra-spec: {"hyperv:remotefx": "1920x1200,1"}. In this case, it means that your vm will have remotefx enabled with 1920x1200 resolution and 1 monitor. Eg:

nova flavor-create m1.remotefx 111 4096 20 2 nova flavor-key 11 set hyperv:remotefx="1920x1200,1"

By doing this, you create a new flavor for remotefx enabled machines.

After this, you just have to boot a new machine with this flavor and it will have a remotefx video adapter.

Note that the valid resolution values for 2012R2 are: 1024x768, 1280 ×1024, 1600 ×1200, 1920 ×1200 and the maximum number of monitors is 4 for resolutions up to 1280x1024, 3 for 1600x1200 and 2 for 1920x1200.

Hello,

Make sure you have enabled the RemoteFX feature on your compute nodes, by setting this config flag in the nova.conf file:

[hyperv]
enable_remotefx = True

Also, make sure you install the RemoteFX feature on your compute nodes:

Install-WindowsFeature RDS-Virtualization

Also, you have to make sure that your hosts are capable of the RemoteFX feature. Some of the requirements are:

• SLAT-enabled processor (Intel: Extended Page Tables (EPT), AMD: Nested Page Tables (NPT)).
• it must support DirectX 11.0 or newer.
• it must support WDDM 1.2 or newer.

Also, you have to make sure that your guests support RemoteFX. For a Windows guest, you can easily check this by looking at its Device Manager > Display Adapters, it should be something like: Microsoft RemoteFX Graphics Device - WDDM.

Finally, we've added support for RemoteFX in Windows / Hyper-V Server 2016, which comes with new features. Some of the new features for RemoteFX in Windows / Hyper-V Server 2016 are:

• 4K resolution option
• 1GB dedicated VRAM (availble choices: 64MB, 128MB, 256MB, 512MB, 1GB) and up to another 1GB shared VRAM
• Support for Generation 2 VMs
• OpenGL and OpenCL API support
• H.264/AVC codec investment
• Improved performance

In order to request a certain VRAM memory amount for your instance, you can create a flavor like this:

# format: resolution,number_of_monitors,vram_amount_in_mb
nova flavor-create m1.remotefx 111 4096 20 2 nova flavor-key 11 set hyperv:remotefx="1920x1200,1,1024"
