VM Machine Boot up error

[SGlo]

Morning All,

I'm really hoping someone can help me out, I know the basics of exsi but not the in depth so be gentle lol - we have a setup of 4 virtual machines on 1 host (capacity of 1.81TB), one machine however doesn't want to boot up it errors with the following message....

Failed to power on VM.

Could not power on VM : Admission check failed for memory resource See the VMware ESX Resource Management Guide for information on resource management settings.

Group vm.260426: Invalid memory allocation parameters for VM vmm0:BT_UC. (min: 2125824, max: -1, minLimit: -1, shares: -1, units: pages)

Group vm.260426: Cannot admit VM: Memory admission check failed. Requested reservation: 2147619 pages

Below are some of the settings we have, I believe this is due to memory or some sort of storage but I just don't know how to resolve. Just to let you know this machine did boot up last week this has only just recently happened :smileyconfused:

the below powered off machine is the one in question

need anymore information then please let me know

Thanks in advance

Do you have "Cluster" and is the host joined to the cluster?

Also did you enable HA on the cluster?

If yes, move your host out of cluster or disable HA.

Because you have standalone host and you don't need to HA.

Admission Control is related to HA and cluster resources, as standard configuration, you need to reserve some of your resource capacity on your cluster.

And you can't power on your machine on reserved resources.

Hi DavoudTeimouriDavoudTeimouri

thanks for getting back to me.

We have 1 standalone host connected to a business network and within that 1 host lies 4 separate VM's.

I wouldnt know where to look to see if HA is enabled?

As you can see on the above screenshot, you can disable/enable your cluster settings.

Right-click on your cluster and then click on Edit Settings

All I get when I right click - edit settings is the below screenshot

I'm using Vmware esxi 5.0 which is possibly why i cannot see what you want me to.

Seems that there is no more physical memory to satisfy that VM configuration. What is the memory capacity for the ESXi server?

[deepaksel]

Hi, seems Memory reservation has been done for the VM's.

Since 8 GB needed for this VM to power on and the available capacity is only 3GB, its not allowing you to power on.

Remove the reservation and try to power on the VM.

Hi, The machine itself doesn't need 8GB to run i just put it to that a while back. I lowered that memory and also took the reservation off and TA-DAAA it worked, thank for your help I shall now retrieve what I need and move what i can off this server.

Enjoy your weekends
