After some testing and digging around the 2.6.32-26 Kernel, Ubuntu port, , it seems to me that KVM creates a separate EPT table for each separate guest CR3 value. So, if there are 100 guest processes, there are essentially 100 EPT tables. Is this correct?
No, it's not correct. Regards, Anthony Liguori
If so, can someone please tell me where these tables are actually being created? Is this design decision a historical artifact from how QEMU/KVM (without EPT/NPT) created multiple shadow page tables so that each guest/virtual CR3 value has a corresponding real CR3 value so that memory based separation for the guest is enforced?
