Both vSphere and Hyper-V offer a capability to move running virtual machines and storage in a single operation, but virtual disks on local storage cannot be protected by HA.
Fault tolerant virtual machines can protect key elements of an infrastructure today, while Windows Hyper-V offers only criticism, press releases, and vaporware.
Why should Hyper-V have all the fun?
Microsoft tried to compare storage performance results from the upcoming Windows Hyper-V 3 with experiments from a year-old vSphere whitepaper that used completely different configurations -- see what happens when similar configurations are used.
The next version of Hyper-V, part of Windows Server 2012, purportedly performs "unlimited" concurrent live migrations.
In what can only be regarded as a breakthrough in hypervisor performance technology, it is now possible to run tier-1 applications on minimal resources and without regard for high-availability of any kind!
The "hosted private clouds" on display at MMS 2012 were based on shared infrastructure, making them public clouds in reality.
Microsoft tipped their hand by announcing a plethora of beta products in 2011, left with little to announce this year at Microsoft Management Summit 2012.
How is a tricked-out bicycle like a System Center 2012 private cloud?
Side-by-side tests show that VMware vMotion is over 5 times faster than Hyper-V Live Migration. Plus, vMotion is more reliable and protects application SLAs much better than Hyper-V.
Independent tests show VMware vSphere 5 outperforms Hyper-V R2 SP1 in overall performance, resource management, and scalability.
Citrix CFO downplays XenServer during Q2 2011 earnings call, shifting focus to Microsoft Hyper-V.
In a recent blog post filled with FUD and misinformation, the Microsoft virtualization team makes a surprising commitment to maintain Windows pricing.
VMware vSphere 5 adds the ability to perform a scripted installation of VMware ESXi 5 to a USB flash drive or SD card. Hyper-V? Not so much.
A recent article on a popular technology media outlet includes misinformed claims about Hyper-V Dynamic Memory advantages over VMware vSphere.
Learn Microsoft's trick behind the claim that VMware vSphere costs as much as five times more than Hyper-V.
Network teaming provides load balancing and fault tolerance to your virtual infrastructure. VMware vSphere provides powerful, elegant solutions to meet the most demanding requirements. The Hyper-V platform continues to rely on unsupported legacy technologies.
Some newcomers to virtualization don't know that VMware vSphere is the combination of VMware ESXi and vCenter Server. By launching a complete virtualization infrastructure platform, VMware can offer more advanced capabilities than the staggered Hyper-V releases from Microsoft.
Latest InfoWorld comparison of all major virtualization platforms puts VMware vSphere on top!
At MMS 2011, Microsoft presented a fake demonstration of Hyper-V Dynamic Memory in a breakout session. But why?
VMware vSphere Resource Pools are a proven means to reliably share infrastructure. Hyper-V requires administrators to manage CPU reservations and limits on an individual VM basis.
Hyper-V Dynamic Memory is coming in SP1, but workarounds may be needed to install applications.
The new Microsoft private cloud "Virtual Machine Manager Self Server Portal 2" takes a major step backward, reverting to the "one VM per LUN" limitation when scripting LUN creation.
Director of Microsoft Virtualization says vSphere hybrid clouds remind him of ancient fax machines, overlooking reality of current IaaS landscape.
Microsoft claims that Linux guests running on Hyper-V are fully supported -- find out what really happens when a customer tries to get help with a SLES VM.
Gartner says Hyper-V not meeting expectations even in midmarket, VMware doing pretty well.
A new feature in vSphere 4.1 allows administrators to easily perform a cold conversion (V2V) of a Hyper-V virtual machine.
Roundup of recent VMware vSphere 4.1 reviews and competitive evaluation resources.
A year ago at MMS 2009, Microsoft criticized VMware for not offering public-private cloud federation. Today, Microsoft still has nothing to show in that area.
The majority of Windows crashes are caused by third-party device drivers. See how Hyper-V reliability is compromised due to its dependence on a general-purpose OS.
Yo Dawg! I heard you like to virtualize, but there is no truth to the rumor that Xzibit influenced the Hyper-V design.
Microsoft has broken through numerous technological barriers, enabling Windows/Hyper-V to directly execute Linux applications.
Humorous take on a reference to small footprint hypervisor advantages -- not from VMware.
With Hyper-V R2 out the door, leaked screenshots from a post-RTM build of Windows Server 2008 R2 suggest a Dynamic Memory feature is coming in a successor.
Microsoft Virtualization publishes an embarrassing guest post refuting vSphere advantages, doing more harm than good.
Learn about Microsoft's attempt to implement memory overcommit in Hyper-V.
In an InformationWeek article, Elias Khnaser does an excellent job of articulating several of the key advantages that VMware vSphere has over Hyper-V -- memory overcommit, hypervisor footprint, maturity, and more.
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.
VMware vSphere 4 offers multiple options for expanding virtual machine storage with zero downtime, including the ability to grow a running virtual disk. Hyper-V marketing literature makes a similar claim, but is limited to simply adding another virtual disk.
According to Microsoft's own documentation, integrating SCOM with SCVMM adds high complexity and additional cost to your virtualization environment.
Microsoft stretches the truth when claiming that VMware adds an additional layer to your architecture. The fact is, Hyper-V relies on its own instance of Windows and requires more instances for running apps.
When a Hyper-V virtual machine console is connected and a live migration is initiated -- automatically with PRO Tips or manually -- the remote client disconnects. The situation must be resolved manually by the administrator, unlike VMware ESX, which seamlessly migrates remote console connections during VMotion.
Hyper-V CSV LUNs have no human-friendly labels, making it difficult for administrators to easily identify volumes. Instead, cryptic GUIDs are shown when monitoring from System Center Operations Manager 2007.
In Windows Server 2008 R2, Cluster Shared Volumes enable multiple hosts to access a single shared LUN. However, administrators may not manipulate or back up VM files on a CSV.
If your server OEM supports it, you might be able to get the free Hyper-V Server R2 to boot from a flash drive someday. VMware ESXi supports this feature today.
Do not believe the hype from Microsoft execs about System Center single pane of glass management. The loosely integrated tools require administrators to use numerous interfaces.
Windows Server 2008 automatically downloads the non-beta Hyper-V patch after installation. If Microsoft is using this metric for Hyper-V deployments, they are not being honest.
Even with the recent move of offering open source (GPL2) Linux integration components (drivers), Linux guests fall quite short of being first-class virtual citizens on Hyper-V.
Microsoft Virtualization was counting Hyper-V downloads -- requried for every Windows Server 2008 system -- and using that metric to imply Hyper-V adoption.
