At long last, we have the packages and the infrastructure set up in what will be (hopefully) the final form for the CentOS 7 Virt SIG Xen packages. Please help us by testing the packages and the infrastructure.
To install the Virt SIG Xen repositories, install the CentOS 7 centos-release-xen package directly from buildlogs:
yum update http://buildlogs.centos.org/centos/7/virt/x86_64/xen/centos-release-xen-7-11...
Because the CentOS packages aren't released yet, they are only available on buildlogs, which are in the (disable-default) centos-virt-xen-testing repository.
So first install the kernel:
yum --enablerepo=centos-virt-xen-testing update
Then install xen:
yum --enablerepo=centos-virt-xen-testing install xen
The version we're starting with is Xen 4.6, which has good systemd support as well as aarch64 support. The version on buildlogs has XSAs through 156 applied.
Libvirt is also available, for those who are so inclined.
Please report any bugs on this list.
Thanks, -George
