创建实例时出错！

Question

1、上传镜像是成功的
glance add name="ubuntu" is_public=true container_format=ovf disk_format=qcow2 < ubuntu.img
2、创建密钥也是成功的
ssh-keygen
cd .ssh
nova keypair-add --pub_key id_rsa.pub mykey
3、创建实例
nova boot --flavor 1 --image 9bab7ce7-7523-4d37-831f-c18fbc5cb543 --key_name mykey myinstance
创建好后如下

为什么状态是ERROR，而且没有IP地址，

Answer 1

1.首先看network服务启动没有
2.其次，是否执行了nova-manage network create 创建IP地址池
3.最后，你的机器是否支持虚拟
Trying to launch a new virtual machine instance fails with the ERROR state, and the
following error appears in /var/log/nova/nova-compute.log
libvirtError: internal error no supported architecture for os type 'hvm'
OpenStack Compute
This is a symptom that the KVM kernel modules have not been loaded.Intel-based processors
If your compute host is Intel-based, run the following as root to load the kernel modules:
# modprobe kvm
# modprobe kvm-intel
Add the following lines to /etc/modules so that these modules will load on reboot:
kvm
kvm-intel
AMD-based processors
If your compute host is AMD-based, run the following as root to load the kernel modules:
# modprobe kvm
# modprobe kvm-amd
Add the following lines to /etc/modules so that these modules will load on reboot:
kvm
kvm-amd
