添加节点显示installfailed
先说添加ovirt节点最近遇到了添加失败，ovirt engine上会显示installfailed，查看日志后发现，有下述信息
Error: Failed to download metadata for repo 'ovirt-4.4-centos-gluster8': Cannot prepare internal mirrorlist: No URLs in mirrorlist在失败节点上执行
dnf makecache也有类似的报错
[root@localhost ~]# dnf makecache
Ceph packages for x86_64 3.9 kB/s | 3.0 kB 00:00
oVirt Node Optional packages from CentOS Stream 8 - BaseOS 6.5 kB/s | 3.9 kB 00:00
oVirt Node Optional packages from CentOS Stream 8 - AppStream 5.9 kB/s | 4.4 kB 00:00
Latest oVirt 4.4 Release 3.9 kB/s | 3.0 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 38 kB/s | 8.6 kB 00:00
CentOS-8 - Gluster 8 69 B/s | 38 B 00:00
Error: Failed to download metadata for repo 'ovirt-4.4-centos-gluster8': Cannot prepare internal mirrorlist: No URLs in mirrorlist由此可知是源的问题，这是因为centos8在2022年后已经停止了，因此需要安装第三方源的ovirt-release，可以使用下述命令进行替换。
dnf --disablerepo=ovirt-4.4-centos-gluster8,ovirt-4.4-centos-opstools,ovirt-4.4-openstack-victoria install -y http://mirror.massclouds.com/ovirt/yum-repo/ovirt-release44.rpm节点证书创建失败
我在添加节点后还是失败，发现相关证书失败，查看日志显示下述信息

...发现是engine上的serial.txt文件缺失，按道理在/etc/pki/ovirt-engine上应该存在一个serial.txt文件的，这里我不知道为什么丢失了
查看这个request，有相似的情况，最后是重新创建该文件并写入1013到文件内。
cd /etc/pki/ovirt-engine
touch serial.txt
echo "1013" >> serial.txt
