thank you for pointing out openvswitch very interesting
wrt the OP
KVM is meant to be much closer to bare metal performance but doesn't
have (at the moment) the all inclusive, easily managed from one
console, turnkey solution to massive virtual installs at the
datacentre level. If you need to be able to remotely provision VMs and
move them whilst live from one centre to another whilst upscaling them
then you will probably need to go with vmware. If you have got the
flattened layer2 setup and have got to the stage of using vSwitch or
the full cisco stack including provisioned nexus1000v then you might
find kvm is a bit of a step backwards.
However i would recommend having a KVM based test suite as judging by
the latest PaaS and IaaS news coming from TUV then a full solution
will be appearing real soon and may be a contender.
If you are just looking to footer about and are after a provisioned
host in a dmz then libvirt can achieve this.
