vbox-cpuhotplug.dsl@ 28345

Last change on this file since 28345 was 26613, checked in by vboxsync, 15 years ago
CPU hotplug: The container has to be there always (you can't remove a CPU socket, only the CPU) and the OSPM needs to check the CPU object not the container during a hot-plug event. Fixes Linux guests not detecting the new CPU after insertion if it was removed before
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
