install virtualbox guest additions ubuntu server 14.04

Do not mix repo and oracle vbox versions - always get both the core vbox stuff from the same place as you get the guest additions and make certain the version numbers match. If you are going to switch, purge the Canonical version before installing the Oracle version. I have been running VirtualBox for long time. Previously I always installed it from the package download on their website never having the recent problem.

Before installing VirtualBox I have made some searches on Internet. Some folk suggested installing it direct on repo because of easy maintenance on update.

I thought the suggestion seeming reasonable. Would it be possible exporting the VM on VirtualBox and importing it on KVM? Would following command line be workable to completely delete the installed VirtualBox? I'm prepared to uninstall it and download the latest package on VirtualBox. KVM can use vdi files directly or you can convert them using vboxmanage or qemu-img. I've been using virt-manager to setup/use KVM VMs - never did it the CLI way except when I had to edit the VM XML directly, then I'd use virsh edit. For Linux VMs, qcow2 might be a good VDI choice. I only have 1 VM with qcow2, the rest are raw/img fully allocated. On Linux, I never had much luck with virtualbox. Be certain you only have 1 hypervisor loaded/installed on the machine at time. You can have a hypervisor AND lxc/containers loaded. If you want to run a desktop OS on a desktop VM host, then virtualbox is probably the best of the free choices. #Virtualbox guest additions download ubuntu 14.04 free If you want to run a server VM on a Linux host, KVM is the best of any choice, IMHO.
