I am pleased to announce the official release of Virt SIG Xen packages for CentOS 7. To install: * Install centos-release-xen from centos-extras yum install centos-release-xen * Update to get the new kernel: yum update * Install the Xen packages from the centos-virt-xen repo: yum install xen There are also packages for libvirt 1.3.0 (which should be compatible with openstack) and virt-manager. Please report any bugs you find in the packaging here. -George
