Issue with Tesla M6 on Cisco B200 M4 after reboot


I have a configuration of GPU M6 (Cisco) installed in B200 M4 blade, and for some reason after reboot this configuration stopped working.

I just can’t power on VM’s on ESXi 6.0U3

Error in VMware:
Failed to start the virtual machine.
Module DevicePowerOn power on failed.
Could not initialize plugin ‘/usr/lib64/vmware/plugin/’ for vGPU ‘grid_m6-4q’.

nvidia-smi showing everything is ok:

Try to find any solutions but only 1 article in VMware about change xorg service, but it is running fine on host.

/etc/init.d/xorg status
Xorg is running

I can see configuration in Web client, and everything seems to be ok for VM configuration.

Is someone have any idea about this issue.

Did open a ticket to Cisco to get some help from support, but also want to get maybe some idea from NVidia forum people.



Is this a new installation or a production one that’s stopped working?

Can you check in vCenter under the "Host Graphics" tab the "Default Graphics Type" is still "Shared Direct"? Also check under the "Graphics Devices" tab that "Active Type" and "Configured Type" are both showing "Shared Direct"?

If the above is correct, then I’d be tempted to uninstall the existing .vib, reboot and reinstall the .vib as that’s nice and quick and non destructive.


Hi BJoned,

This is a production host stopped working. I think your suggestion is related to v.6.5 not to 6.0U3.

For some reason I can’t change BIOS setting on blade for Memory Mapped IO above 4gb Config to disabled. If I uninstall card from blade it is changed to Disable, but once card in blade it is Enabled automatically and not allowing to change to Disable.

Yes, sorry, that’s for 6.5. Haven’t used 6.0 since 6.5 was released and forgot that setting is not part of 6.0

That’s fine, MMIO above 4G should be “Enabled”.

If all you’ve done is rebooted the server, then I’d still try the uninstall / re-install of the .vib and see if that helps. If you’ve applied some updates or made changes to the system somewhere, then obviously review those again …


Ok, I resolved an issue, for some reason :-) gpumode for GPU change to Compute… EVEN I got output below before switch it again to Graphics.

Before reflash GPU to Graphics mode
