Hi everybody.
I have two esx 3.0.2 and vcenter 2.0.2. Each esx have 8 gb of memory.
ESX1:
VM1: 4164 MB / Host memory usage: 1gb / guest memory usage: 43MB
VM2: 4164 MB / Host memory usage: 3.3gb / guest memory usage: 157MB
VM3: 2084 MB / Host memory usage: 2.5gb / guest memory usage: 100MB
The question is... why my esx1 showme the red alarm (host memory usage) if the VM's only uses 300MB ...
What i can do to decrease the host memory usage?.
Thanks
Do you have VMware Tools installed for each VM?
Is there a memory reservation set on each VM or in a resource pool that the VM is a member of?
Does each VM really need 2-4GB of allocated RAM?
Vmtools are installed in all VM's.
The configuration of all VMs is:
Shares: normal
Reservation: 0MB
Limit: Unlimited
Host mem and guest mem can be mis-leading because of all the memory tricks ESX does. Read these posts for mroe info on this...
