Looks like the host (AHV) is in maintenance mode. Can you paste the output of this command: acli host.list

If the host in not schedulable then make it schedulable by running: acli host.exit_maintenance_mode <host_AHV_IP_Address>

​@JeroenTielen 

I have done the above, but, the host still reports as “Schedulable == False”

Still trying to figure this out.

Looks like the host got some network issues. It is still not connected. (Connected=false)

In my blog there is a section about the vmware virtual switch. Did you set those settings according the blogpost?

​@JeroenTielen 

Yes, I setup the Security policy settings.  

It is setup as VMXNET3.  I didn’t see any specific reference in your guide.  Maybe switch over to the Intel NIC emulation?

Well, I changed the NIC type to E1000, and still no change.  Connected=False, Schedulable=False

The CPU requirements are not very specific.  I have dual E5 2667 V2 processors; which is good for what I want to run inside Nutanix.  I’ve read about plenty of people using Dell R720 servers and Nutanix CE. 

I’m running out of ideas.

Did you try a reinstall? Maybe something wasnt right from the beginning. 

I have re-installed 3-4 times, no change in the result.  It will not run a simple VM.

I will turn on the ESX server and install a CE again and update the blogpost with the network interface,. 

Blogpost is updated with more detailed information. Can you try it again? And please, follow the steps exactly. 

​@JeroenTielen 

Are there any specific logs that I can check to determine why the host is not schedulable?

Your example shows vCenter 8.  I am using ESXI 7.0U3.  I don’t know if that would be a difference.

I’ll give it another go this afternoon and re-look at your website.

The esx server i used this week was also 7 ;). Works the same. 

Same problem here - is there a solution know? Network is ok, AFAIK enough resources but still PC VM refuses to start

Note: downloaded latest available PC offered in PE

​@ClausP do you have a screenshot of your error? 

Hey Jeroen, 

when trying to boot up the PC VM after deployment iPE reported “Operation failed nohostresources ..:” while plety resources available and same like Chris (Scheduleable and Connected false which is quite funny as I was connected with Putty directly to the CVM from my workstation over the physical network))

I am now going with a new installation from scratch to see if there’s any difference (before I know I did not set the disk.EnableUUID parameter

Will report if it should bring up a more positive outcome. 

Regards! 

Claus 

Same issue here

please, keep posting if you find a solution

Thanks

Running into the same issue as well.  I’m using an older Dell R620 and ESXi 6.5 Nutanix CE 2.1 Single Node Cluster but followed the blogpost perfectly and only failed when I tried to power on a VM I created.  I tried both VMXNET 3 and currently trying E1000e

Error in Prism UI: Operation failed: NoHostResources: No host has enough available resources for VM 93d7d42e-ab36-44cd-8c03-4961cbacff75.: 14

I noticed in Prism under network configuration that there is no vswitch defined at all.  Thought that was weird. Created a subnet with vlan 0.

Followed same troubleshooting as here and see the same issue with my CVM not able to get out of maintenance mode

I SSH into the AHV host and checked service ahv-host-agent status and found this error, hoping this will help if others have the same error and somebody knows what to do:

If you change the network card (vmxnet3 to e1000e) you need to run a script (nic_add_or_replace) or reinstall the node.
