The available memory resources in the parent resource pool are insufficient for this operation

Hello,

   I have been trying to power on a Nexus 1000V VM running on an ESXi 5.1 on a vSphere vCenter 5.5 and i keep getting an error message concerning available memory resources. I am running on a Virtual server with 10GB RAM and 60GB HDD. The Physical host machine has 16GB RAM and 320GB HDD. I am a beginner in this so please try to be clear. Thank you very much.

Hi,

It is possible that you have a memory reservation set on the 1000v (I think the template comes with them as standard when you deploy).

if you right click the VM and "Edit settings" and then go to the "resources" tab, under the "Memory" section, do you have anything set by the reservation?

It would look like this : http://i.imgur.com/ftBZENv.png

If it has a reservation, you could safley set it to 0MB (removes the reservation). This might be preventing it from powering up.

Failing that, are you running a cluster within vCenter? Do you have HA enabled?

Thank you very much. The VM is powered on.

Hello Guys,

For some reason the OVF has a reservation set for all the memory you allocate to it…

Edit the settings, click resources, click memory and slide the reservation to 0.

The available Memory resources in the parent resource pool are insufficient for the operation.
