AHV host is unschedulable

Hello,
Just wanted to know if anyone else here experienced this issue where the host in my single node cluster is not schedulable. Here is the output from acli host.get

nutanix@NTNX-CVM:~$ acli host.get REDACTED

172.xxx.x.xx {

  cpu_usage_ppm: 0

  host_overhead_bytes: 0

  logical_timestamp: 1

  max_mem_ha_reserved_bytes: 0

  mem_assigned_bytes: 0

  mem_usage_bytes: 0

  memory_size_bytes: 0

  node_state: "AcropolisNormal"

  num_cpus: 0

  pool_size_bytes: 0

  schedulable: False

  uuid: "REDACTED"

}

 

Initial issue I had was that I cannot power-on the VM due to this error:

NoHostResources: No host is schedulable: 14

 

And after checking this host scheduling thing is what I thought of the culprit on why I cannot power-on my UVM. Already the following:


1. Enter/exit maintenance mode
2. Restart the CVM / AHV Host

Also noticed that the Prism element Hardware tab shows 0 usable CPU/RAM capacity on this AHV host. I use the version 6.8.1 and it is installed as a VM in an ESXi host.

Hi,

Kindly check followings.

nutanix@NTNX-CVM:~$ cluster status | grep -v UP

You may also try to stop/start cluster
nutanix@NTNX-CVM:~$ cluster stop
nutanix@NTNX-CVM:~$ cluster start

Also it is important to check that how much resources you have assigned to your AHV (running as VM on ESXi).
