Let's say I have an ESXi 5.1 host which has 2 quad-core processors with Hyper Threading, for a total of 16 logical processors. If I have a very CPU-hungry VM that I want to give 8 vCPUs to, would it be better to span across NUMA nodes, or apply the numa.vcpu.preferHT=TRUE configuration to force the VM to stay on a single NUMA node and use Hyper Threading instead? I'm interested in both obtaining optimal performance for this VM while ensuring that the other (much less CPU intensive) VMs running on this host don't get CPU starved or block this VM from accessing the CPU.

One time-saving feature in Workstation is Easy Install - if I want to make a quick one-use throwaway VM, I can just point Easy Install to the OS installation ISO, click Next a bunch of times, wait ~10 minutes, and I have a usable VM. Is there anything similar in ESXi?
Is there a KB article with more details on that issue? If its impact is severe enough then I'm not going to even bother testing, so it'd be good to know.

I'm thinking of either getting a dirt cheap SATA PCIe card to run the boot/datastore drive and passing my onboard ICH10DO through to a VM, or using the onboard ICH10DO to run the boot/datastore drive and passing through the PCIe SATA controller. Since it seems the SIL3132 is no longer compatible with ESXi, what alternatives are there?

What do I need to do in order to get ESXi to recognize a USB flash drive? I haven't been able to get ESXi to recognize my USB drive as either a device attached to the host or as a device that I can pass through to a VM - it's as if it simply doesn't exist.

I installed ESXi 5.5 on my test box and discovered to my surprise that, unlike in prior releases, ESXi did not automatically reformat all attached disks into datastores. Next, when I tried to create a datastore manually, I got a "Call "HostStorageSystem.ComputeDiskPartitionInfo" for object "storageSystem" on ESXi failed" error, which has me wondering - is this a new feature/change in behavior, or is it simply a bug in 5.5?

How is the console rendered these days? Having recently moved from 4.1 to 5.5, I must say that I was quite surprised when I used the console for the first time. Whereas the 4.1 console was pretty run-of-the-mill by remoting standards, the 5.5 console experience felt almost local - for a moment I thought I was running a local VM on VMware Workstation. Is this PCoIP I'm seeing?
The VM I'm using to host the web client is the vCenter Server Appliance 5.5a that VMware provides as a downloadable OVF/OVA file. It's an SLES 11 image with 2 vCPUs and 8 GB of RAM.
Just to clarify, are you asking about the spec of the ESXi server, the spec of the VM that's running vCenter Server, or the spec of the laptop that's running the web browser?

I'm testing the vSphere Web Client, but I'm finding it unbearably slow - it takes almost 5 minutes just to log on, and every click after I'm in takes a good 30 seconds before the new page is done loading. I think I spent a good 10 minutes in total simply getting to the screen where I could power on a VM, which is something that can been done in less than a minute using the traditional desktop client. Have I horribly misconfigured the web client in some way?

From an enterprise perspective, it's not all that strange. From an optimistic point of view, testing takes time and enterprises generally don't demand to upgrade on day 1 anyway, so just because your board isn't on the HCL today doesn't mean that it won't be on the HCL 3 months from now. IBM for instance has slowly but steadily been adding their servers to the ESXi 5.5 HCL over the past month and a half - many systems that were not on the HCL back in September are now officially supported. On the other hand, it's possible that Intel has simply dropped ESXi support for your board, especially if they don't sell it anymore. It all depends on how the hardware vendor views the platform and how much of an impact they expect the customer backlash will have.
Was support dropped in the sense that it now shows up on this list and no longer works in ESXi 5.5, or does your board simply no longer appear on the HCL? If it's the latter case, my understan...

Was support dropped in the sense that it now shows up on this list and no longer works in ESXi 5.5, or does your board simply no longer appear on the HCL? If it's the latter case, my understanding is that everything needs to be recertified for 5.5, and new devices are being added to the HCL on a regular basis. It may simply be a matter of time, especially if your hardware is new enough to still be in production.
