I like it only because it was one the first commercial companies which supported Linux by releasing VMWare … A quel punto mi son detto: provare non costa nulla. All results from VMware must be discarded for comparison purposes. For example, the slower show of VMware can be simply due to some host-side work that the system was doing in that precise moment. Here is a snapshot of the hypervisors we reviewed and a bit about each: KVM – a Linux based open source hypervisor. Is worth note that, in write test, VMware is the only virtual machine that has a good boost from increased queue depth. I don't like VMWare (Workstation) because it's commercial, closed source and really heavy. Discussion in 'Other Operating Systems' started by nix_guru, Aug 29, 2010. VirtualBox è probabilmente la scelta migliore per gli utenti che desiderano una semplice applicazione per l’esecuzione di sistemi operativi mainstream senza mai dover toccare un file di configurazione o aprire un terminale. Xen-HVM has device emulation based on the QEMU project to provide I/O virtualization to the VMs. But three tools dominate the market: VirtualBox, VMware, and Microsoft Hyper-V. For years, Xen and VMware have been the virtualization technologies of choice for open source operating systems vendors. For give you a more precise view, I reported the raw write test data in a table: As you can see, KVM, Xen and VMWare behave in very different manners, but they are all much behind VirtualBox.

The fact that Xen, KVM, and VirtualBox run on a linux install doesn't really matter because they all run within the kernel, as does ESX except that ESX has it's own kernel rather than running in the linux kernel. Plus, the kernel modules needed for KVM are part of the Kernel, no need to build modules (like VirtualBox does) or patch the Kernel (like Xen requires). This can be a results of a more-heavy hypervisor or, more probably, of the “double encapsulation” of the guest system. If that's the case, go with KVM with VFIO, I'm not sure if VirtualBox supports GPU passthru as well as KVM does. That graph shows that in the read test VirtualBox and VMware are the most CPU hungry hypervisor – but they have much greater I/O results than the others. It seems that Xen do a very good use of the nested page table feature.
