oVirt4.2开源虚拟化安装笔记4-后续遇到的问题处理

设置Cockpit服务(WEB界面管理Node服务器)自动启动

重启host主机后发现之前用的那个web管理主机的界面访问不了了,翻了一下文档,发现其实那个功能是一个叫cockpit的服务提供的,默认没有设置开机自动启动,所以重新设置一下这个服务:

[html] view plain copy

print ?

1. [root@node1 ~]# systemctl enable cockpit  
2. [root@node1 ~]# systemctl start cockpit  
3. [root@node1 ~]# systemctl status cockpit  
4. 鈼[0m cockpit.service - Cockpit Web Service  
5.    Loaded: loaded (/usr/lib/systemd/system/cockpit.service; static; vendor preset: disabled)  
6.    Active: active (running) since Mon 2018-04-23 10:49:27 CST; 4s ago  
7.      Docs: man:cockpit-ws(8)  
8.   Process: 2598 ExecStartPre=/usr/sbin/remotectl certificate –ensure –user=root –group=cockpit-ws –selinux-type=etc_t (code=exited, status=0/SUCCESS)  
9.  Main PID: 2603 (cockpit-ws)  

[root@node1 ~]# systemctl enable cockpit 

[root@node1 ~]# systemctl start cockpit 

[root@node1 ~]# systemctl status cockpit 

鈼[0m cockpit.service - Cockpit Web Service 

   Loaded: loaded (/usr/lib/systemd/system/cockpit.service; static; vendor preset: disabled) 

   Active: active (running) since Mon 2018-04-23 10:49:27 CST; 4s ago 

     Docs: man:cockpit-ws(8) 

  Process: 2598 ExecStartPre=/usr/sbin/remotectl certificate --ensure --user=root --group=cockpit-ws --selinux-type=etc_t (code=exited, status=0/SUCCESS) 

 Main PID: 2603 (cockpit-ws)

部署NTP服务器及虚机自动同步时间

在ovirt-engine服务器上部署ntp服务,让所有的虚机从engine服务器上自动同步时间

1.安装ntp服务

[html] view plain copy

print ?

1. # yum install -y ntp  

# yum install -y ntp

2.设置ntp服务开机自动启动

[html] view plain copy

print ?

1. # systemctl enable ntpd  
2. # systemctl start ntpd  

# systemctl enable ntpd

systemctl start ntpd

虚拟机上设置时间自动同步

Windows系统:

CentOS7系统:

[html] view plain copy

print ?

1. # yum install ntp //安装ntp服务  
2. # systemctl enable ntpd //开机启动服务  
3. # systemctl start ntpd //启动服务  
4. # timedatectl set-timezone Asia/Shanghai //更改时区  
5. # timedatectl set-ntp yes //启用ntp同步  
6. # vi /etc/ntp.conf    //注释掉原有的server开头行,增加server 10.41.58.26  
7. # ntpq -p //同步时间  

# yum install ntp //安装ntp服务

systemctl enable ntpd //开机启动服务

systemctl start ntpd //启动服务

timedatectl set-timezone Asia/Shanghai //更改时区

timedatectl set-ntp yes //启用ntp同步

vi /etc/ntp.conf //注释掉原有的server开头行,增加server 10.41.58.26

ntpq -p //同步时间

调整虚拟机时区偏移设置

新建的虚机有个时区与配置不同的提示,需要修改一下相关设置

更新方法:

直接在engine服务器上修改默认时区设置:

[html] view plain copy

print ?

1. # engine-config -s DefaultGeneralTimeZone=‘Asia/Shanghai’  
2. # systemctl restart ovirt-engine  

# engine-config -s DefaultGeneralTimeZone='Asia/Shanghai'

systemctl restart ovirt-engine

重启ovirt-engine服务后在后台新增虚拟机可以看到时区已经默认为+8了

Ubuntu17.10及其他不支持的Guest操作系统安装ovirt guest agent

根据官方文档,虚拟机中Guest OS只支持以下操作系统发行版本:

Supported Guest Distributions

Once oVirt is running and you have configured a Host, you can proceed to install any number of supported operating systems as guest virtual machines.

Operating System	Architecture		SPICE support
Red Hat Enterprise Linux 3	32-bit, 64-bit		Yes
Red Hat Enterprise Linux 4	32-bit, 64-bit		Yes
Red Hat Enterprise Linux 5	32-bit, 64-bit		Yes
Red Hat Enterprise Linux 6	32-bit, 64-bit		Yes
Red Hat Enterprise Linux 7	64-bit		Yes
SUSE Linux Enterprise Server 10 [1]	32-bit, 64-bit		No
SUSE Linux Enterprise Server 11 [2]	32-bit, 64-bit		No
Ubuntu 12.04 (Precise Pangolin LTS)	32-bit, 64-bit		Yes
Ubuntu 12.10 (Quantal Quetzal)	32-bit, 64-bit		Yes
Ubuntu 13.04 (Raring Ringtail)	32-bit, 64-bit		Yes
Ubuntu 13.10 (Saucy Salamander)	32-bit, 64-bit		Yes
Windows XP Service Pack 3 and newer	32-bit		Yes
Windows 7	32-bit, 64-bit		Yes
Windows 8	32-bit, 64-bit		No
Windows 10[3]	32-bit, 64-bit		Yes
Windows Server 2003 Service Pack 2 and newer	32-bit, 64-bit		Yes

Windows Server 2008 R2	64-bit		Yes
Windows Server 2012 R2	64-bit		No
Windows Server 2016	64-bit		No

[1] select Other Linux for the guest type in the user interface
[2] SPICE drivers (QXL) are not supplied by Red Hat. Distribution’s vendor may provide SPICE drivers.
[3] 64-bit only. SPICE upstream drivers are also available

对于更高版本的Ubuntu或者其他Linux发型版本,可以参照官方的文档从github上下载源代码自行编译,下面是官方提供的编译流程,下面的示例对应的是在Ubuntu 12.04上进行的编译操作:

Building from source

Packages for Ubuntu 12.04 do no longer exist, so you will have to build from source:

1. Install dependencies

# sudo apt-get update

sudo apt-get install -y pkg-config pep8 libtool usermode python-ethtool git autoconf make

1. Clone Git repository

# cd /tmp

git clone https://github.com/oVirt/ovirt-guest-agent.git

1. Select a version to build

# cd ovirt-guest-agent

git checkout 1.0.14    //在Lubuntu 17.10上没有进行这一步检出老版本的操作

1. Configure, build and install

# ./autogen.sh

./configure –prefix=/usr –without-sso

make

sudo make install

sudo chmod +x /usr/share/ovirt-guest-agent/ovirt-guest-agent.py

1. Create an Upstart script to start the service when booting

# sudo sh -c 'echo "description \"oVirt Guest Agent\" 

start on local-filesystems 

stop on runlevel [!2345] 

respawn 

exec /usr/share/ovirt-guest-agent/ovirt-guest-agent.py 

" > /etc/init/ovirt-guest-agent.conf' 

1. Reboot or start the service manually

# sudo service ovirt-guest-agent start 

Troubleshooting

The web admin interface may take some time to start displaying the memory usage and other types of information. If you find that after some time this information has not been populated, restart the VM by performing a shut down or power off, power on, and verify that the service is started by running. A reboot of the virtual machine did not seem to resolve the issue.
