Convert userspace_msr_exit_test to use vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is a "functional" change in the sense that the test now creates a vCPU with vcpu_id==0 instead of vcpu_id==1. The non-zero VCPU_ID was 100% arbitrary and added little to no validation coverage. If testing non-zero vCPU IDs is desirable for generic tests, that can be done in the future by tweaking the VM creation helpers. Opportunistically use vcpu_run() instead of _vcpu_run() with an open coded assert that KVM_RUN succeeded. Fix minor coding style violations too. Signed-off-by:

Convert memslot_perf_test to use __vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID. This is the first of many, many steps towards eliminating VCPU_ID from all KVM selftests, and towards eventually purging the VM+vcpu_id mess. Signed-off-by:

Return the created vCPU from vm_vcpu_add() so that callers don't need to manually retrieve the vCPU that was just added. Opportunistically drop the "heavy" function comment, it adds a lot of lines of "code" but not much value, e.g. it's pretty obvious that @vm is a virtual machine... Signed-off-by:

Add ____vm_create() to be the innermost helper, and turn vm_create() into a wrapper the specifies VM_MODE_DEFAULT. Most of the vm_create() callers just want the default mode, or more accurately, don't care about the mode. Signed-off-by:

Rename vm_create_without_vcpus() to vm_create() so that it's not misconstrued as helper that creates a VM that can never have vCPUs, as opposed to a helper that "just" creates a VM without vCPUs added at time zero. Signed-off-by:

Rename vm_create() to vm_create_barebones() and drop the @phys_pages param. Pass '0' for the number of pages even though some callers pass 'DEFAULT_GUEST_PHY_PAGES', as the intent behind creating truly barebones VMs is purely to create a VM, i.e. there aren't vCPUs, there's no guest code loaded, etc..., and so there is nothing that will ever need or consume guest memory. Freeing up the name vm_create() will allow using the name for an inner helper to the other VM creators, which need a "full" VM. Opportunisticaly rewrite the function comment for addr_gpa2alias() to focus on what the _function_ does, not what its _sole caller_ does. Signed-off-by:

Open code adding and doing setup for a vCPU in get-reg-list in order to avoid the stack allocation that comes with aarch64_vcpu_add_default(). get-reg-list doesn't need to run the vCPU, and so doesn't need the guest to be backed with memory. This will allow future cleanup to turn what is current vm_create() into a barebones helper. Signed-off-by:

Move the call to vm_adjust_num_guest_pages() from vm_create_with_vcpus() down into vm_create_without_vcpus(). This will allow a future patch to make the "w/o vCPUs" variant the common inner helper, e.g. so that the "with_vcpus" helper calls the "without_vcpus" helper, instead of having them be separate paths.
