Currently, the presence of a pKVM handle (pkvm.handle != 0) is used to determine if the corresponding hypervisor (EL2) VM has been created and initialized. This couples the handle's lifecycle with the VM's creation state. This coupling will become problematic with upcoming changes that will allocate the pKVM handle earlier in the VM's life, before the VM is instantiated at the hypervisor. To prepare for this and make the state tracking explicit, decouple the two concepts. Introduce a new boolean flag, 'pkvm.is_created', to track whether the hypervisor-side VM has been created and initialized. A new helper, pkvm_hyp_vm_is_created(), is added to check this flag. All call sites that previously checked for the handle's existence are converted to use the new, explicit check. The 'is_created' flag is set to true upon successful creation in the hypervisor (EL2) and cleared upon destruction.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
