MachineImpl.h@ 74910

Last change on this file since 74910 was 72919, checked in by vboxsync, 6 years ago
Main/*: From now on any valid UTF8 string is considered a valid guest OS type. Of course not all of them are known, so the API clients must be prepared to deal with not having a matching IGuestOSType object. Frontends/VBoxManage+VBoxShell: adjust to deal with the change
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
