KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V).

• pool-refresh default - rescan default pool for new images

virt-manager doesn't pick the best options for the clock and, as consequence, the CPU usage is quite high. Replace the clock section with:

  <clock offset='localtime'>
    <timer name='hpet' present='yes'/>
    <timer name='hypervclock' present='yes'/>
  </clock>
