Someone with a solution?

[SIGSTKFLT]

I have the same issue. Did you find a solution?

Edit: refer to #6 as it may help.

[TechyGuy17]

I moved to normal vpgu_unlock

[mbilker]

If you wanted to investigate this further, what were the earlier nvidia-vgpu-mgr.service log messages, especially the ones before the stack trace and the vgpu_unlock-rs-specific log messages?

[TechyGuy17]

Sorry But i cant access that. I were in a bit of a hurry to get it working and had to move on and reinstall. So all that is gone. But thanks anyways!

You are allowed to close this or keep it for others with same problem :)

[mbilker]

I'm going to close this. Most of the issues I've seen can usually be troubleshooted by reading more of the log and vgpu_unlock-rs will cause a VM startup to fail if the config file is not formatted correctly too.
