Subject: libxl: add API wrapper for libxl_retrieve_domain_configuration
X-Git-Tag: v7.3.0-rc1~389
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=17855c5ca01d283a3bcaceeff96971491e6a6b44;p=thirdparty%2Flibvirt.git

libxl: add API wrapper for libxl_retrieve_domain_configuration

Upcoming changes will use different LIBXL_API_VERSION variants.

Prepare libxl_retrieve_domain_configuration, which got a new parameter
"libxl_asyncop_how" in Xen 4.12. libvirt does not use this parameter.

No functional change intended.
