We have two Supermicro SYS2027GR-TR2 servers that were running XenServer 6.2 SP1. Each system has one NVIDIA GRID K1 video card installed. We just upgraded the servers to XenServer 6.5 by doing a clean install, and upon restarting and installing the nvidia driver rpm with rpm -iv NVIDIA-vgx-xenserver-6.5-340.57.x86_64.rpm, our cards are not healthy per XenServer.

Output of lsmod | grep nvidia:

nvidia              10548578  26

Output of dmesg | grep -E "NVRM|nvidia":

XenServer does not show any GPU tab and VMs cannot be assigned to use a vGPU, only a pass-thru GPU. We've followed the install instructions included with the nvidia driver package. Has anyone else run into this?

  • This might be due to the new license requirement in XS6.5 can you try applying the XenServer for xendesktop + license? – user265572 Jan 18 '15 at 0:03
  • @Jared - It looks like that might be part of the issue. We don't have a license for anything currently but we can purchase one or get a trial and see if that fixes the issue. – cathode Jan 19 '15 at 17:21
