Open Infrastructure

A customer requested, because our vm-s start slow because of entropy starvation.

A fix is to add the pcie device, however easily we can only fix this for new vms:
http://docs.opennebula.org/5.8/deployment/open_cloud_host_setup/pci_passthrough.html

because we are using the qemu backend we could somehow add it live to existing vm-s but it would require more effort:
https://www.linux-kvm.org/page/Hotadd_pci_devices

we could recommend our users to install haveged but:
"The quality of the generated entropy is not guaranteed and sometimes contested"¹
