Subject RE: Cloudstack/Xenserver/GPU support
Date Fri, 20 Jun 2014 05:48:55 GMT
Hi Vijay,

If you want to use the GPU/vGPU functionality in CloudStack then you need to install "XS62ESP1"
hotfix on top of XenServer 6.2.0. Once you are done with patch installation, reconnect the
host or restart the management server so that CloudStack can detect the GPU cards present
in XS host.

Also, as of now, CloudStack UI only supports NVIDIA k1 and NVIDIA k2 cards, so if you are
using any other card apart from these two, than you need to make API call the API call "createServiceOffering"
as mentioned in "Web services APIs" section here: https://cwiki.apache.org/confluence/display/CLOUDSTACK/GPU+and+vGPU+support+for+CloudStack+Guest+VMs

Please let me know if you any more queries.

--Sanjay

The problem is that my host doesn’t show the gpu through cloudstack. Just using Xenserver
direct passthrough, everything works. Just doesn’t work through cloudstack.

From the FS [1], under Interoperability and compatibility, it is supported for 6.2 SP1 and
later.
