METHOD AND APPARATUS FOR SUPPORTING VIRTUALIZATION OF LOADABLE MODULE

摘要

The present invention relates to a virtualization support method and a device thereof. A virtualization support method given in the present invention includes a step of starting source code transformation of a loadable module; a step of searching for a virtualization sensitive command; a step of, if any virtualization sensitive command is found, generating a virtualization sensitive command table based on the found virtualization sensitive command; a step of converting the virtualization sensitive command to a command readable in a privileged mode based on the virtualization sensitive command table; and a step of running the loadable module by mounting the module in a kernel. By doing so, the overhead cost due to full-virtualization can be minimized and high performance in semi-virtualization can be guaranteed without source modification.
