[XEN PATCH 0/3] libxl: Implement QEMU command line probe

Posted by Anthony PERARD 2 months, 3 weeks ago

Patch series available in this git branch:
https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.libxl-qemu-cmdline-probe-v1

Starting with QEMU 9.0, the option "-chroot", that we use for the
"dmrestrict" feature, is removed. We need to find out which to use
between "-chroot" and "-run-with chroot=dir".

Also, "-runas" is deprecated in QEMU 9.1 and will be remove in a future
release, it's replaced with "-run-with user=user".

To find out which command line option we can use, we'll spawn QEMU, and run the
QMP command "query-command-line-options".

Some example of running these patches:
    with qemu-xen (8.0):
        http://logs.test-lab.xenproject.org/osstest/logs/187352/
    with QEMU (upstream, 9.1-rc3):
        http://logs.test-lab.xenproject.org/osstest/logs/187353/

  libxl: Probe QEMU for -run-with chroot=dir and use it
  libxl: Probe QEMU for -run-with user=user and use it
