The following KVM and virtualization changes are included in this release of UEK 8:

• Two-Dimensional Paging (TDP) MMU support is added to significantly improve page fault performance on many-VCPU VMs. This functionality is enabled by default.

• The UEK 8 kernel configuration for VCPUs is increased to a theoretical limit of 4096. Note that the actual vCPU limit is use case specific and dependent on many factors including system and QEMU configuration.
