Moving to syscalls avoids these problems, but introduces new ones:
- adding new syscalls is generally frowned upon, and kvm will need several
- syscalls into modules are harder and rarer than into core kernel code
- will need to add a vcpu pointer to task_struct, and a kvm pointer to
mm_struct
- Lost a good place to put access control (permissions on /dev/kvm)
for which user-mode processes can use KVM.
How would the ability to use sys_kvm_* be regulated?
