Find all virtual machines with ballooned or swapped RAM in VMware cluster?

If I were to look at a vSphere cluster or resource pool and see a certain level of memory ballooning or swapping, how do I identify which VMs are affected? I know what to do with them once I find them :)

In the example below, there are 65 virtual machines in the resource pool. There’s just under 32 Gigabytes of ballooned…

How can I setup vSphere so that VLAN tags are not stripped at the vSwitch?

I am trying to test a VLAN-related networking issue, so I thought that firing up a couple virtual machines would be the easiest and cleanest method to test the problem. On the vSphere server I created a new vSwitch with no adapters bound, then created a new VM Network with VLAN tag 0 (disabled.)

I created two VMs and put…

How to: Why doesn't VMWare DRS automatically migrate VMs when a host is put in maintenance mode? #answer #solution #development

Why doesn’t VMWare DRS automatically migrate VMs when a host is put in maintenance mode?

We have 4 ESXi 5.0 hosts in a VMWare cluster on shared storage (NFS) with DRS and HA on.

We want to perform a memory upgrade on one of the hosts. We put that host in maintenance mode but DRS did not automatically live migrate the VMs.

I’m thinking it has something to do with our settings:

Do I need VMWare vSphere?

I’m planning use vmware to upgrade some of very aged server instead replace with all new bunch of server. VMWare vSphere sounds great but because of low budget I can’t afford for both licenses and SANs. Without SAN, is vSphere worth the price? As I know without SAN, the VMWare HA, VMontion, FT is unavailable. So, do I need vSphere or only ESXi free version assume that I…

vSphere education – What are the downsides of configuring VMs with *too* much RAM?

VMware memory management seems to be a tricky balancing act. With cluster RAM, Resource Pools, VMware’s management techniques (TPS, ballooning, host swapping), in-guest RAM utilization, swapping, reservations, shares and limits, there are a lot of variables.

I’m in a situation where clients are using dedicated…

VMware Distributed vSwitches (VDS) – Design, theory, *real* use cases and examples?

I’m starting to explore VMware Distributed Switches (dvSwitches or VDS) for use in existing and new installations. Assume VMware version 5.1 and newer with Enterprise Pluslicensing. Prior to this, I’ve made good use of standard vSwitches defined with the right types of physical uplinks (1GbE or 10GbE) and managed…

Server health monitoring software

Hey all! I am looking for some software to monitor the health status of our servers. Our environment is a pretty typical mix of HP/Dell running Microsoft Server and VMware vSphere. We are currently using WhatsUPGold and would like to migrate away from that. I have been checking out Dell Management Console and IT Assistant but I think it seems troublesome to get…
