Most Popular Virtualization

Hey Guys, I was wondering, if you could suggest when to use KVM virtualization, Xen and VMWare. Which one do you think is the most popular among the various virtualization offerings in the market. Appreciate your help folks. Thanks.

Shalom,

Impossible to say.

Red Hat has backed KVM. It works on the command line a lot like HP-UX npar/vpar, which anyone that has used it really likes.

Xen has been around the longest and has the installed base.

VMWare is huge as well but is always looking for money.

Re: Most Popular Virtualization

hi,

its depend how much money do you like to spend and which functionality do you really need. Its always about this.

we tested :

Vmware vSphere 4 and also Update1
XenServer 5.5

HyperV - no way for us. ( try to test but don't found the satisfiction )


From the Vmware / Xen we decided to use and buy in the future the Vmware ESX 4.

On many forums i readed that the KVM is very well for Linux virtualisation, but in our company we are using only HP-UX and Windows.

Re: Most Popular Virtualization

My company is in the middle of an extensive study on integrating virtualization. The finalists seem to be at this point:

1) Sun VirtualBox (for desktop use, free)
2) VMware ESXi (for stuff not needing huge backend support, free)
3) VMWare ESX (for stuff needing backend support like SANs and failover, not free)
4) Sun Containers (for Solaris and Sparc virtualization, not free)

The best kernel based virtualization is Virtuozzo which is based on OpenVZ. Try both, you will never regret you did!

Re: Most Popular Virtualization

If you're using Redhat, Ubuntu or Centos -- hands down -- use KVM or it's commercial implementation -- RHEV.

For Small Biznesses -- they don't even have to go RHEV as KVM modules can easily be added. Ubuntu's distro makes it even easy to add and configure KVM and is *FREE*

Undoubtedly vMware was first to market and are much much more user friendly specially via the VI infrastructure and vsphere/ESX 4.0 is just so EAZY a 5th grader can manage it. But it costs money... and does not scale quite well as KVM which officially supports up to 16 virtual CPUs allocated to a Virtual Machine under its wingz.

There are even experiments done by a large IT vendor recompiling KVM and tested Virtual Machines being able to sscale up to 64 vCPUs and above.

KVM actually can do now much of what vShere/ESX can with some pluses to to it. My experience so far has shown Virtual Machines under KVM to be more responsive and faster than the rest. Of course, with the absence of performance benchmarks "officially" from vMware -- each will be left to do their own tests.
