2.kvmmodulesareloaded(kvm,kvm_amd|kvm_intel)

解决方法：

1.必须安装虚拟化套件支持

1	[root@kvm01agent] # yum-ygroupinstall'Virtualization''VirtualizationClient''VirtualzationPlatform''VirtualizationTools'

2.确认kvm模块已经被正确加载

[root@kvm01~]

#
lsmod|grepkvm

kvm_intel525700

kvm3147391kvm_intel

如果没有任何信息，请使用如下命令加载kvm模块：

1 2	[root@kvm01~] # modprobekvm_intel##intel平台 [root@kvm01~] # modprobekvm_amd##amd平台

3.再次添加。

福利：

关于添加主机过程中的错误，千奇百怪，而java的报错又。。。教给大家一个小技巧：

当添加主机报错，日志中有没有明确原因时，可以手动在agent上面执行添加主机的命令。具体添加主机的命令可以在management的日志中获得：

比如我上面的例子,得到如下命令，并在agent上面执行：

这个过程中，如果报错，就很轻易就能判断出问题是出在哪一步。

另外，上面cloudstack-setup-agent命令的参数如下，根据自己的情况改写：
