commit ebaa23ffb84d8bf8a114e67d49041d9afdee3a56 Author: Roger Pau Monne <roger.pau@xxxxxxxxxx> AuthorDate: Fri Nov 13 17:38:06 2015 +0000 Commit: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx> CommitDate: Fri Feb 5 14:54:56 2016 +0000 xen: fix usage of xc_domain_create in domain builder Due to the addition of HVMlite and the requirement to always provide a valid xc_domain_configuration_t, xc_domain_create now always takes an arch domain config, which can be NULL in order to mimic previous behaviour. Add a small stub called xen_domain_create that encapsulates the correct call to xc_domain_create depending on the libxc version detected.
