It is possible to create a VCPU without setting the MSR before running it, which results in a warning in kvmhv_vcpu_entry_p9() that MSR_ME is not set. This is pretty harmless because the MSR_ME bit is added to HSRR1 before HRFID to guest, and a normal qemu guest doesn't hit it. Initialise the vcpu MSR with MSR_ME set.

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 Restructured Text 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.
