Unable to start the VM from Proxmox Cluster

[Sean Png]

Hi,

We have tried to start a VM from Proxmox but getting an error below,

=======
TASK ERROR: command 'ha-manager set vm:100 --state started' failed: exit code 255
=======

First got an error " TASK ERROR: NUMA needs to be enabled for memory hotplug " and I have enabled it from Hardware>> Processor. After that, I am getting this above error. Also, the VM status is stopped and the HA state is error. Please help in this case.

Thank you.

Hi,

Somebody here to help in this case?

try to disable HA on the vm first, then start it again, maybe you'll have more information.

if you have enable NUMA + memory hotplug, the memory size should be a multiple of 1024 too.

Hi,

I am noob in the Proxmox. Can you please let me know how to disable HA from the VM? Also, may I know if there will be any issue to disable it?

Also, I could see that the memory is 32768 now.

The same way where you have enable it ->datacenter->HA , on the ressources list, remove the vm from HA.

>>Also, may I know if there will be any issue to disable it?
No, just HA will not be enable.


(BTW, if you are new to Proxmox, my recommandation is to play with it a little bit,before enable HA. (and for HA, read carefully the documentation).

Hi,

Thank you for the detailed explanation.

I have found the option from Datacenter. May I confirm again if the VM will not have any issues after removing it?

So sorry for the trouble again.
