Changes in v2 from the cover letter
1) Incorporated feedback:
- DR6/DR7/CR2/DEBUGCTL should not be need.
- HSAVE should be set to a different page for each vCPU
- The on_cpu to set EFER should be in setup_svm
- The on_cpu to set cr0/cr3/cr4 should be in setup_vm.
2) Execute tests on selected vcpu using on_cpu_async so the tests may use the on_cpu functions without causing an ipi_lock deadlock.
3) Added additional test svm_init_startup_test which inits the vcpu and restarts with sipi.
