ustcweizhou opened a new pull request #3879: kvm: Enable virtio drivers based on guest os display name URL: https://github.com/apache/cloudstack/pull/3879 ## Description <!--- Describe your changes in detail --> 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.
