Hi, Based on the feedback I received over the e820 reserve patch, I have changed it to have QEMU pass in a list of entries that can cover more than just the TSS/EPT range. This should provide the flexibility that people were asking for. The Seabios portion should allow for unlimited sized tables in theory, whereas for QEMU I have set a fixed limit for now, but it can easily be extended. Please let me know what you think of this version! Cheers, Jes
