[libvirt] [libvirt-php] libvirt_domain_new Create a slow vm

[Mario Di Ture]

Hi,

I've tested this script on centos 6.5 (libvirt-0.10.2, qemu-kvm-0.12.1.2)
and
ubuntu server 14.04 (libvirt 1.2.2, qemu-kvm  2.0.0) with the same result.
The created vm is very slow compared to the vm created with virt-manager,
with the same features/devices on the same host.
Can you suggest any configuration that can avoid that slowness?

With regards
Mario D.
