Re: Linux/KVM's shell far better
Flexibility in the sense that an image can be converted to other hypervisors 'easily', the ability to resize partitions inside an vm image regardless in they are the first partition on the disk (i.e /dev/sda) - see virt-resize. Flexibilty due to the fact you can script in a Linux environment which is years ahead of 'power'shell.
There is a reason most of the big hardware players are fully supporting and getting behind KVM - i.e IBM, HP, Intel i.e
http://openvirtualizationalliance.org/blog/why-does-hp-believe-in-open-source
"KVM is a great fit for HP customers. Using HP cloud-optimized servers; web hosting service providers can roll their own infrastructure, enterprise customers can deploy integrated hardware and software solutions, and everyone can deploy application workloads in the HP Cloud."
> Hyper-v Server has outperformed KVM ever since the release of Hyper-V Server 2008 R2
Utter rubbish = seriously do benchmarks, KVM out performs Hyper V in IO by a serious margin when setup correctlyu - i.e LVM + virtio + correct cache settings.
> Fro instance show me a KVM host running a single VM with 1 million IOPS like Microsoft demonstrated last year?
KVM has achieved World Record IOPS: 1,402,720 IOPS

> Also worth noting that KVM is limited by having to run on top of a Linux OS, whereas Hyper-V Server is a dedicated Hypervisor OS (like VMware ESXi)...
You do know that ESXI is still forked from the Linux kernel also - see ovirt (ovirt.org) - its a Linux ESXI equivalent.
It should like at least half your beliefs are just assumptions not fact.
