这里要介绍一下使用ovirt engine管理平台进行oVirt宿主机的部署.

oVirt的架构介绍参考 : 

http://www.ovirt.org/Architecture

部署oVirt宿主机, 宿主机需要联通网络, 配置ovirt yum源, 配置DNS可以解析ovirt yum源, 另外宿主机的CPU需要支持虚拟化, 同时在BIOS打开虚拟化开关, 等.

本文部署HOST节点的主机为DELL R610, E5504的CPU.

部署步骤 : 
1. 首先检查宿主机的CPU是否支持虚拟化, 并且在BIOS开启它.

2. 然后需要给宿主机安装CentOS 6.x x64.

3. 配置宿主机的主机名, 最好整个oVirt环境部署DNS, 用于解析所有的宿主机和管理机, 存储的主机名.

没有的话, 需要配置/etc/hosts. 

# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
172.16.3.40 40.sky-mobi.com

# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=40.sky-mobi.com

# vi /etc/resolv.conf
nameserver 202.101.172.35

4. 配置防火墙, 打开宿主机和存储网络, 与ovirt engine的连通性. 

# vi /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -s 192.168.0.0/16 -j ACCEPT
-A INPUT -s 10.0.0.0/8 -j ACCEPT
-A INPUT -s 172.16.0.0/16 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

# service iptables restart

5. 配置时钟同步 

# yum install -y ntpdate
# crontab -e
8 * * * * /usr/sbin/ntpdate asia.pool.ntp.org && /sbin/hwclock --systohc

# /usr/sbin/ntpdate asia.pool.ntp.org && /sbin/hwclock --systohc

6. 关闭SELINUX  

# setenforce 0
# vi /etc/selinux/config
SELINUX=disabled

7. 配置limit.conf, sysctl.conf 

vi /etc/sysctl.conf
kernel.shmmni = 4096
kernel.sem = 50100 64128000 50100 1280
fs.file-max = 7672460
net.ipv4.ip_local_port_range = 9000 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_max_syn_backlog = 4096
net.core.netdev_max_backlog = 10000
vm.overcommit_memory = 0
net.ipv4.ip_conntrack_max = 655360
fs.aio-max-nr = 1048576
net.ipv4.tcp_timestamps = 0

# sysctl -p

# vi /etc/security/limits.conf
* soft    nofile  131072
* hard    nofile  131073
* soft    nproc   131072
* hard    nproc   131073
* soft    core    unlimited
* hard    core    unlimited
* soft    memlock 50000000
* hard    memlock 50000001

# vi /etc/security/limits.d/90-nproc.conf
#*          soft    nproc     1024
#root       soft    nproc     unlimited
* soft    nproc   131072
* hard    nproc   131073

8. 配置yum 

yum localinstall -y http://plain.resources.ovirt.org/pub/yum-repo/ovirt-release34.rpm
[root@40 ~]# cd /etc/yum.repos.d/
[root@40 yum.repos.d]# ll
total 24
-rw-r--r--. 1 root root 1926 Nov 27  2013 CentOS-Base.repo
-rw-r--r--. 1 root root  638 Nov 27  2013 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  630 Nov 27  2013 CentOS-Media.repo
-rw-r--r--. 1 root root 3664 Nov 27  2013 CentOS-Vault.repo
-rw-r--r--. 1 root root 1498 Jul 31 22:33 ovirt-3.4-dependencies.repo
-rw-r--r--. 1 root root  292 Jul 31 22:33 ovirt-3.4.repo

关闭gpg校验
# vi ovirt-3.4-dependencies.repo
# vi ovirt-3.4.repo
gpgcheck=0

9. 配置宿主机的硬件管理卡, 用户权限, 开放LAN IPMI功能, 测试fence接口.


 

10. 使用ovirt-engine管理平台添加主机, 并配置电源管理模块, 有很多FENCE接口, 我们这里使用ipmi, HP的话可以使用ilo. 其他厂商的自己参考一下厂商的说明.


 

11. 如果安装有错误的话, 可以查看host的event, 或者到ovirt engine主机查看日志 /var/log/ovirt-engine/host-deploy/*.log

1. 在HP DL360 G5 E5405的机器上部署host节点失败.

报错如下 

Host 176 is missing the NX cpu flag. This flag can be enabled via the host BIOS. Please set Disable Execute (XD) for an Intel host, or No Execute (NX) for AMD.  Please make sure to completely power off the host for this change to take effect.

配置如下, nx 配置enable , disable都一样, 每次到配置的最后会自动重启, 并且无法配置虚拟网卡.

最终的报错信息2条, 貌似是CPU的问题, 少了一个特性 : 

Host 176 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt'
Host 176 moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_Nehalem

罢了, 用这台老机器来做ovirt-engine节点吧, HOST节点还是用比较给力的CPU.

oVirt host deploy的相关文章

vdsm on oVirt HOST depend multipathd but must manual modify blacklist in multipath.conf

oVirt支持NFS, GlusterFS, FC, iSCSI等存储方式, 所以对于HOST节点, 在加入oVirt后, 可能出现一点小问题, 某些设备变成了dm设备, 并且用以前的方式无法挂载了. oVirt这么做的目的应该是配合FC和iSCSI的使用, 因为一般FC和iSCSI都可以用到多路径来获的链路冗余. 无法以原设备名挂载, 原因是vdsmd这个服务依赖multipathd服务. [root@150 etc]# cd /etc/init.d/ [root@150 init.d]# g

oVirt guest | VM & HOST HA in one Cluster

oVirt支持虚拟机的HA配置, 当集群中有合适的机器可以接管failed的宿主机上的虚拟机时, 这些虚拟机会自动在同集群下的合适的主机上运行. 但是有几个前提条件 :  1. Power management must be configured for the hosts running the highly available virtual machines. 需要配置HA的虚拟机, 它的宿主机的电源管理必须配置. 2. The host running the highly avail

oVirt engine 3.4 installed on CentOS 6.x x64

oVirt是RHEV的上游开源产品, 管理也和RHEV非常相似, 主打KVM的虚拟机管理平台. 相比OpenStack更加轻量化. 本文先介绍一下oVirt engine在CentOS 6.x x64平台下的安装. 除了数据库我们使用自己编译的PostgreSQL 9.3.5, 因为从依赖安装的版本实在太老了. 其他都使用依赖安装. 导入yum源 # wget http://resources.ovirt.org/pub/yum-repo/ovirt-release34.rpm # rpm -i

oVirt Reports Portal 3.4 added to ovirt-engine

配置完oVirt engine后, 可以进行用户管理和虚拟化平台的管理, 但是无法生成报告. 如图, 点击Reports Portal会告诉你没有安装report application. 安装ovirt engine可参考昨天发的一篇文章. http://blog.163.com/digoal@126/blog/static/1638770402014628114756319/ engine report建议在engine配置前就安装, 那么只需engine-setup时可以直接配置. 现在的
