CentOS 7 - Extras for x86_64: system environment/base: centos-release-xen-414
centos-release-xen-414 - CentOS Virt Sig Xen repo configs for Xen 4.14
yum configs and scripts to allow easy installation of Xen 4.14 on CentOS.
Multiple versions of centos-release-xen-NNN can be installed at the
same time; by default yum will choose the latest version of xen
available across all repositories.
This package will not update automatically to newer Xen releases;
if you don't have centos-release-xen installed, you will have to
manually install the newer version of centos-release-xen-NNN to get the
newer version. If this is not the behavior you want, please install
the generic package (centos-release-xen).
