Dynamic table configuration in a virtual machine
View Patent ↗A system, method, and software product provides for managing resources in a virtual machine. The system comprises a guest memory and a processor. The guest memory stores a file exception table and a file inclusion table. The file exception table indicates at least one first name of a host resource. The file exclusion table indicates at least one second name of a guest resource. The processor receives a resource query, processes the resource query to determine a host weight value using a weighting operation and the file exception table. The processor also processes the resource query to determine a guest weight value using the weighting operation and the file inclusion table. Additionally, the processor compares the host weight value to the guest weight value to determine whether the resource query is associated with the host resource or the guest resource.
1. A system for managing resources in a virtual machine, the system comprising:
a guest memory configured to store a file exception table comprising at least one first name of a host resource and a file inclusion table comprising at least one second name of a guest resource; and
a processor configured to:
receive a resource query, process the resource query to determine a host weight value using a weighting operation and the file exception table, process the resource query to determine a guest weight value using the weighting operation and the file inclusion table, and compare the host weight value to the guest weight value to determine whether the resource query is associated with the host resource or the guest resource;
determine whether the resource query matches the at least one first name of the host resource or the at least one second name of the guest resource;
receive a query directory command and process the query directory command to obtain first results according to the file exception table;
process the query directory command to obtain second results according to the file inclusion table and blend the first results with the second results to produce blended results; and
write the guest resource to the guest memory.
2. The system of claim 1 wherein the at least one second name of the guest resource comprises a registry filename.
3. The system of claim 1 wherein the at least one first name of the host resource is associated with a kernel object.
4. A method for managing resources in a virtual machine, said virtual machine having coupled therein a processor and a memory, said method comprising:
storing a file exception table comprising at least one first name of a host resource in a guest memory;
storing a file inclusion table comprising at least one second name of a guest resource in the guest memory;
receiving a resource query;
processing the resource query to determine a host weight value using a weighting operation and the file exception table;
processing the resource query to determine a guest weight value using the weighting operation and the file inclusion table;
comparing the host weight value to the guest weight value to determine whether the resource query is associated with the host resource or the guest resource;
determining whether the resource query matches the at least one first name of the host resource or the at least one second name of the guest resource;
receiving a query directory command and process the query directory command to obtain first results according to the file exception table;
processing the query directory command to obtain second results according to the file inclusion table and blend the first results with the second results to produce blended results; and
writing the guest resource to the guest memory.
5. The method of claim 4 wherein the at least one second name of the guest resource comprises a registry filename.
6. The method of claim 4 wherein the at least one first name of the host resource is associated with a kernel object.
7. A software product for managing resources in a virtual machine, the software product stored in a storage readable medium when executed by a processor cause a computer to perform the steps:
storing a file exception table comprising at least one first name of a host resource in a guest memory;
storing a file inclusion table comprising at least one second name of a guest resource in the guest memory,
receiving a resource query,
processing the resource query to determine a host weight value using a weighting operation and the file exception table,
processing the resource query to determine a guest weight value using the weighting operation and the file inclusion table, and comparing the host weight value to the guest weight value to determine whether the resource query is associated with the host resource or the guest resource;
receiving a query directory command and process the query directory command to obtain first results according to the file exception table;
processing the query directory command to obtain second results according to the file inclusion table and blend the first results with the second results to produce blended results;
determining whether the resource query matches the at least one first name of the host resource or the at least one second name of the guest resource;
writing the guest resource to the guest memory.
8. The software product of claim 7 wherein the at least one second name of the guest resource comprises a registry filename.
9. The software product of claim 7 wherein the at least one first name of the host resource is associated with a kernel object.
