kvm: Enable virtio drivers based on guest os display name (#3879)

Browse Source 
When we add new guest os, sometimes we missed the records in guest_os_hypervisor.
However, the guest disk model (virtio/ide) is determined by record in the table.
It causes the issue that some new guest os(eg Debian 8/9) uses e1000 instead of virtio nic, and ide disk instead of virtio disk.

To fix the issue permanantly, pass the guest os name in guest_os if the record for kvm is not found in guest_os_hypervisor.
