Hello,<div>We are using libvirt over KVM. If we run a single virtual machine on a host</div><div>then the performance is very good but if more than one vm (with 1:1 provisioning)</div><div>runs on same host the performance is very poor (specially in case of parallel programming).</div>



<div><br></div><div>libvirt version: 0.9.2</div><div>qemu-kvm-0.14.1</div><div><br></div><div>We are using virtio module also.</div><div>What could be the possible reasons for this behavior. Please tell me if you need more info.</div>
