由于国内用户访问oVirt官方源速度较慢，经与oVirt官方社区对接，现设立国内镜像yum源，以为广大国内用户提供服务！

可以使用下面的repo文件替换掉你环境中的（位置在/etc/yum.repos.d/）：
oVirt4.4：
http://mirror.massclouds.com/opencloud/ovirt-4.4.repo
oVirt4.3：
yum安装怎么使用？
正常的话会自动从mirrorlist选择，不好使的话用改一下/etc/yum.repos.d/ovirt-4.4.repo文件吧（4.3版本对应的把下面的4.4替换成4.3）：
# imgbased: set-enabled
[ovirt-4.4]
name = Latest oVirt 4.4 Release
# baseurl = https://resources.ovirt.org/pub/ovirt-4.4/rpm/el$releasever/
baseurl = http://mirror.massclouds.com/ovirt/ovirt-4.4/rpm/el$releasever/
enabled = 1
gpgcheck = 0
# gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-ovirt-4.4
# includepkgs = ovirt-node-ng-image-update ovirt-node-ng-image ovirt-engine-appliance
按照改法也不行
