VM distribution between hosts (XenServer) in the same cluster

[Florin Dumitrascu <fl...@intunenetworks.com>]

Hi everyone,

I am testing at the moment with CS 4.1.1 and XenServer 6.1
I have 2 hosts in the same cluster. At the moment 3 VMs run on the first host which is pretty much all it can handle in terms of memory.
But when I try to start the 4th VM, CS keeps trying to deploy on the same host and fails. Why is it not picking the second host which is free ?
Am I missing something from the global config ?

Thanks for your help,
Florin

Hi Harikrishna,

Please find attached the management server log. You can look for 'HOST_NOT_ENOUGH_FREE_MEMORY' error.
The second host had enough capacity to start the 4th VM. I was able to deploy the 4th VM on the second host only after reducing the "Global Settings -> Hypervisor Capabilities ->Max guest limit" , thus forcing the VM on the second host.
Is this the way it should work ?

Thanks for your feedback,
Florin

Hi,
Can you share the management logs. Is the host has enough capacity to deploy 4th VM ?
