Although the KVM solution discussed here may work, the description of this in operation appears to be a true hypervisor even when only used to run, say, MS Windows as an application environment virtual machine under SL. That is, this solution is not the same "in spirit" as is VirtualBox. On a hard 802.3 wired connection, VirtualBox does provide Internet access to the outside world from the guest; this seems to be a failure on a 802.11 ISP wifi connection. JHas anyone used VMware-Player-12.0.0-2985596.x86_64.bundle on a SL7 host with a MS Win guest? If so, is the "free" version stripped of sufficient features as not to be useful in a "production" environment? I do not need merely to look at pretty pictures of a running guest environment; I need to access the Internet. to share files (e.g., docx, pptx, etc.) between the Linux host and the MS Windows guest, and to access both USB devices and the DVD drive of the host on the guest. My institution cannot afford the US$249 for the VMware Workstation license, and I cannot justify the expenditure of research funds. However, VMware player is licensed for free for non-commercial private use (mine). I do note that my query on the failure of VirtualBox to work with 802.11 host Linux networks and thus supply a connection to the guest OS within VirtualBox now has had 46 views on the VirtualBox Linux host "forum" without a reply -- evidently, this is a problem with the current VirtualBox for which no one has a viable solution -- hence my interest in VMware Player.
