openstack平台创建实例时报错找不到有效的宿主机,请各位帮帮忙,谢谢!
搭建了一个两节点的openstack平台,一个计算节点,一个控制节点,单网卡,nova-network
控制节点网络配置
auto eth0
iface eth0 inet static
address 10.21.1.228
netmask 255.255.0.0
gateway 10.21.0.98
broadcast 10.21.255.255
network 10.21.0.0
计算节点
auto eth0
iface eth0 inet static
auto br100
iface br100 inet static
address 10.21.1.200
netmask 255.255.0.0
gateway 10.21.0.98
broadcast 10.21.255.255
network 10.21.0.0
bridge_ports eth0
bridge_fd 0
bridge_stp off
创建nova-network时用了命令 nova network-create demo-net --bridge br100 --multi-host T --fixed-range-v4 203.0.113.24/29
报错好像和这个命令有关.
