无可用资源0000 / 0000

问题：无法创建eucalyptu实例，使用euca2命令查看资源如下:

[root@localhost node]# euca-describe-availability-zones verbose
AVAILABILITYZONE        hell_euca       192.168.0.8
AVAILABILITYZONE        |- vm types     free / max   cpu   ram  disk
AVAILABILITYZONE        |- m1.small     0000 / 0000   1    128     2
AVAILABILITYZONE        |- c1.medium    0000 / 0000   1    256     5
AVAILABILITYZONE        |- m1.large     0000 / 0000   2    512    10
AVAILABILITYZONE        |- m1.xlarge    0000 / 0000   2   1024    20
AVAILABILITYZONE        |- c1.xlarge    0000 / 0000   4   2048    20

原因：cc指向的nc错误，可能是指向的cc本身
解决方法：重新注册cc节点和nc节点
