A new feature in vSphere 4.1 allows administrators to easily perform a cold conversion (V2V) of a Hyper-V virtual machine.

While Microsoft marketing material claims Hyper-V and SCVMM can transfer large virtual machine files and templates over a SAN, the truth is that all VM transfers are done over the network. Only VMware ESX leverages high-speed storage area networking for VM migration.
When a datastore in your VMware vSphere environment is about to fill up, you can have vCenter automatically spring into action to prevent downtime by using Storage VMotion.
vSphere makes it easy for administrators to see which virtual machines in a cluster are using CPU and memory.
If you have used VMware VI3 and vSphere 4, one thing you probably noticed right away is the difference in licensing. To much applause, vSphere no longer uses a FLEXlm license server. While you transition from VI3 to vSphere you will still need to keep the license server around, though. Fortunately vCenter Server 4 is […]
With SCVMM, VM templates are generalized with Sysprep before storing in the image library -- the original VM is destroyed and cannot be updated. vCenter only Syspreps after cloning.
Snapshots have always been a powerful feature of VMware ESX — even in production deployments. There are tons of innovative tools and scripts out there to monitor snapshots — just check out this new one from Virtu-Al. If you happen to want a simple, built-in way to monitor your snapshots in VMware vSphere 4, look […]
As tasks and events happen in vCenter Server they are logged in the VC database. After a while these tables can become quite large. Prior to vCenter Server 4, customers wishing to prune their VC database down needed to do so manually. VMware provides an SQL script via KB 1000125 that allows administrators to delete […]
VMware officially launched vSphere earlier this week, and it’s great! I just took the gold vCenter Server 4.0 for a spin and rolled the camera while I was at it. This video starts off with the installation of vCenter Server and the vSphere client, then I add an ESX 4 host and walk through the […]
VirtualCenter (vCenter) database storage requirements grow rapidly as administrators increase the levels from default settings.
As vCenter Server (VirtualCenter) collects performance data, it is stored in the VC database. As the data ages, it is aggregated to save storage space.
SCVMM adds a custom attribute to VirtualCenter (vCenter).
Yesterday, Network World published this article: Microsoft’s SC-VMM provides limited view of VMware-based VMs. I’ve quoted some of the best parts and followed each with some additional resources to reinforce the author’s points. Using SC VMM to initially make a VM image instance wasn’t easy or intuitive. Ahh, that sounds like this issue regarding VMware […]
When you centrally manage multiple virtualization hosts, what measures can be taken to protect the manager itself from outages? While availability could be a concern at first glance, a management platform like VMware vCenter can generally tolerate a short outage without too many folks noticing — VM workloads would never be affected. One exception is […]
Yesterday I was sifting through my email and noticed a little promo blurb to an article written about the VMware vCenter on Linux technical preview: That teaser was clearly written by someone unfamiliar enough with Linux and databases to confuse the two. Hint: vCenter for Linux is a VM appliance — the distro is irrelevant […]
Yesterday I wrote a summary of the hazards of using SCVMM to manage VI3 — highlighting previously published VCritical articles as well as linking to a new series of videos on Why Choose VMware. Looks like VMware may have hit a nerve, as the Microsoft virtualization team scrambled to issue a barrage of rebuttals. My […]
Features found in VMware ESX are unnecessarily neutered when attempting to manage by using System Center Virtual Machine Manager 2008.
VMware vCenter 2.5 Update 4 was released this week and the top bloggers already covered some of the important changes in this release. I wanted to take a moment to explain a nice improvement with the recent vCenter (VirtualCenter) releases that may have gone unnoticed. First, some background: VMware makes extensive use of build numbers […]
vCenter on Linux is distributed as a virtual appliance; it is really easy to try out. However, the only supported database at the moment is Oracle — this might be a stumbling block for some. While the installation guide covers everything you need to know, here are some quick tips that may help clarify some […]
VMware recently announced the new VMware ESXi Management Kit. If you have up to three free ESXi servers deployed and would like to manage them with vCenter Server, this is a great opportunity. Available until April 30 for $995. The kit includes: VMware vCenter Server Foundation vCenter Agents for 3 ESXi hosts (2 CPU sockets […]
Even though the VI Client does not offer creation of VMs with thin-provisioned disks, they may exist. Use a PowerShell script to identify them.
When System Center Virtual Machine Manager (SCVMM) connects to VirtualCenter/vCenter, several changes are made. Learn how to recover everything with PowerShell.
Wow, System Center Virtual Machine Manager 2008 (SCVMM) sure plays rough with VirtualCenter vCenter. I found that every time I restart the SCVMM server it kills all VI Client connections. That is not very nice. But then again, neither was deleting my ESX templates.
When using System Center Virtual Machine Manager to manage VMware ESX, VMs are removed from their resource pools during migration with VMotion.
