ovirt-node和ovirt-engine相连遇到的问题解决办法

1.  Host 192.168.70.7 does not comply with the cluster Default emulated machines. The Hosts emulated machines are <UNKNOWN> and the cluster is rhel6.4.0}

   问题定位：[root@lijiejun yum.repos.d]# /usr/libexec/qemu-kvm 
                     /usr/libexec/qemu-kvm: symbol lookup error: /usr/libexec/qemu-kvm: undefined symbol: usbredirparser_send_start_bulk_receiving

   解决方法： yum install usbredir-server.x86_64

   成功现象：/usr/libexec/qemu-kvm -machine ?

2.  Host installation failed. Command returned failure code 1 during SSH session '[email protected].*.*'
     1）查看/etc/yum.repos.d里面的源是否齐全，必须有ctvn.repo,还要有Centos-*的源
     2）查看是否能ping通外网
     3）/etc/init.d/rpcbind restart   /etc/init.d/vdsmd restart

3.  FATAL: Error inserting kvm_intel (/lib/modules/2.6.32-431.17.1.el6.x86_64/kernel/arch/x86/kvm/kvm-intel.ko): Unknown symbol in module, or unknown parameter (see dmesg)
     # dmesg
      kvm_intel: Unknown parameter `nested'
      解决方法：进入目录--/lib/modules/2.6.32-431.17.1.el6.x86_64/kernel/arch/x86/kvm/ 手动加载模块
                       # insmod kvm-intel.ko

                       # modprobe kvm-intel

4.  查看vdsm配置项:  vdsClient -s 0 getVdsCaps

5.  Error: No such file or directory: '/proc/net/iet/session'
      #rpm-qa|grep vdsm
      看看是不是安装了CTVO,安了要卸载它
6.   no response
      #/etc/init.d/vdsmd status

7.  后端vdsm.log报错--- cpu model 不符合

     问题定位：#rpm -qa|grep qemu-kvm
     如果不是出现下面的版本就有问题了

                       qemu-kvm-1.5.3-19.5.el6.x86_64
                       qemu-kvm-common-1.5.3-19.5.el6.x86_64
                       qemu-kvm-tools-1.5.3-19.5.el6.x86_64
    解决办法：重新安装qemu-kvm，版本要是-1.5.3的
