Install QEMU on ubuntu 14.10 and mange QEMU with Virt Manager
When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests.
The virt-manager application is a desktop user interface for managing virtual machines through libvirt. It primarily targets KVM VMs, but also manages Xen and LXC (linux containers). It presents a summary view of running domains, their live performance & resource utilization statistics. Wizards enable the creation of new domains, and configuration & adjustment of a domain’s resource allocation & virtual hardware. An embedded VNC and SPICE client viewer presents a full graphical console to the guest domain.

You can open virt-manager from dash by searching "virtual machine manager"
Once it opens you should see similar to the following screen
You can create new virtual machine by clicking on "Name"
This will complete the new VM creation and from here you can install Guest OS on this VM.
