新手求助！无法启动实例

由于是“新手上路”，无法在openstack学习法帖求助，只能在本版发帖求助。

在启动一个实例的时候，
[mw_shl_code=bash,true]nova boot --flavor m1.tiny --image cirros-0.3.4-x86_64 --nic net-id=3be58b93-32ad-42bb-80c7-7979554d6bc4 --security-group default --key-name demo-key demo-instance8[/mw_shl_code]
出现了错误：

查看nova-compute.log，出现了如下的警告信息：

计算在计算节点和控制节点都看看。还有看看三个节点hosts配置是否有问题。

“计算在计算节点和控制节点都看看。”是指？


controller和network是在同一个节点上了，compute占用一个节点，hosts没有问题
另外：
执行
[mw_shl_code=bash,true]tail -300 /var/log/nova/nova-compute.log | grep "WARNING"[/mw_shl_code]

有这样的几条：

hypervisor是KVM还是什么？
为何这么安装

是KVM啊

要怎么安装啊？

什么版本，nova-network，还是neutron

Alkaloid0515 发表于 2015-8-26 11:49

neutron

另外把controller和network安装到了同一个节点上，compute单独一个节点

是按照文档装的，还是自己琢磨着的。
最好分开装

执行这条命令

[mw_shl_code=bash,true]egrep -c '(vmx|svm)' /proc/cpuinfo[/mw_shl_code]

返回值是什么

Alkaloid0515 发表于 2015-8-26 13:49
执行这条命令

执行命令后，返回24

按照官方文档安装的，由于硬件所限，只能把controller和network安装到同一个节点
