CS4.22 GPU Server Unable to create a VM #12216
Description
problem
Unable to create VMs getting 504 error
The server is recognized a GPU enabled.
Using a regular template with UBUNTU 22.04
Using a Service created, the service is as all our server but has a GPU. HA, and i checked the Video just to test.
on the agent logs shows:

On the Server, there is no errors or disconnections.
the storage ID for this VM shows
ID

I am able to reach the primary storage from the GPU Host.
Except for this error and after 45 minutes the System keeps spinning on creating the VM "Launch Instance in progress"

versions
The versions of ACS, hypervisors, storage, network etc..
ACS 4.22.0
KVM for the GPU and other hosts
CEPH RDB primary storage
NFS secondary storage
VXLAN running same as the other servers.
Ubuntu 22.04 as a Hypervisor
Ubuntu 22.04 as template - Same template used for other VMs.
The GPU is recognized by the system with no problems.
The steps to reproduce the bug
- Using a GPU service offering with HA and GPU Display true - we do have disabled the OOB management.
- Add a simple VM isolated network, using a GPU Offering 1GPU.
- Everything starts ok, VR is created on a regular CPU server -automatically, Storage is created, Ip addresses allocated
- Instance creation fails after 35+ minutes.

Please Guide us on the proper setting.
Thank you

Just noticed after 50 minutes the ggpu serve becomes in alert mode and It's impossible to restart the GPU agent.
It just does not restart the agent on the GPU server.
Force-reconnect does not work
Have to restart the KVM Host.
So far the only servers not able to create a VM are the ones that contain a GPU.

@tatay188 I am not sure if this is because of the GPU server. Can you enable debug logs on the agent and share the logs again? Also, are you able to launch a non-GPU VM on GPU Enabled Host by manually selecting the host during VM start?

I did deployed on the GPU server a regular VM Ubuntu server, with no problem at all, the AGENT in debug mode shows several warnings with libvirt:

And that's it, there is nothing else there. the non GPU VM is running with no problems, what do I do to eliminate those errors? as the libvirt QEMU is the version as it comes with cloudstack, not sure the hyperversor and libvirt versions have a mismatch, but did not want to change anything!
Let me know how you want me to proceed on this lab.
