Re: [PATCH v2 2/4] qemu: avoid launching non-x86 guests with 'pvspinlock' setting

The 'pvspinlock' feature is x86 only. The "<pvspinlock/>" declaration will always have a value 'on' or 'off', and both will break QEMU when launching non-x86 guests. This is the error message for "<pvspinlock state='on'/>" when running a ppc64 guest: qemu-kvm: Expected key=value format, found +kvm_pv_unhalt A similar error message is thrown for "<pvspinlock state='off'/>". This patch prevents non-x86 guests from launching with any pvspinlock setting with a more informative error message: error: unsupported configuration: The 'pvspinlock' feature is not supported for architecture 'ppc64' or machine type 'pseries' Suggested-by: Andrea Bolognani <abologna(a)redhat.com&gt; Signed-off-by: Daniel Henrique Barboza <danielhb413(a)gmail.com&gt; --- src/qemu/qemu_domain.c | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-)
