openstack Train版本安装（compute有异常待处理）

openstack Train版本安装（compute有异常待处理）
compute节点有异常

这几天测试用用CentOS7做了 T 版和用 CentOS8 测试做了 V 版的openstack都是这个情况，都是在compute节点上启动 libvirtd.service 和 openstack-nova-compute.service 服务时就报 kernel doesn't support AMD SEV
不确定是我宿机的CPU问题还是其他哪里的问题，等待高手指点

宿机：intel I7-6700 / 24G /1T机械盘

虚机：Vmware Station 16 pro

Openstack T版安装

openstack官方kvm文档

KVM 被配置为 Compute 的默认管理程序。
要显式启用 KVM，请将以下配置选项添加到 /etc/nova/nova.conf文件中：
compute_driver = libvirt.LibvirtDriver
[libvirt]
virt_type = kvm

对于基于 x86 的系统确定是否存在svm或vmxCPU 扩展
grep -E 'svm|vmx' /proc/cpuinfo
如果 CPU 能够进行硬件虚拟化则此命令会生成输出。即使显示输出，您可能仍需要在系统 BIOS 中启用虚拟化以获得全面支持。
如果没有出现输出需确保您的 CPU 和主板支持硬件虚拟化。验证是否在系统 BIOS 中启用了任何相关的硬件虚拟化选项。
每个制造商的 BIOS 都不同。如果必须在BIOS中启用虚拟化，查找包含单词的选项 virtualization，VT，VMX，或SVM。
要列出加载的内核模块并验证kvm模块是否已加载
lsmod | grep kvm

如果输出包括kvm_intel或kvm_amd，kvm则加载硬件虚拟化模块并且您的内核满足 OpenStack Compute 的模块要求。
如果输出未显示kvm模块已加载
modprobe -a kvm

对于英特尔CPU运行命令
modprobe -a kvm-intel

对于AMDCPU运行命令
modprobe -a kvm-amd

嵌套访客支持
要启用嵌套KVM的客人，你的计算节点必须加载 kvm_intel 或 kvm_amd与模块nested=1。
您可以nested通过创建一个命名的文件/etc/modprobe.d/kvm.conf并用以下内容填充它来永久启用该参数：
vim /etc/modprobe.d/kvm.conf
options kvm_intel nested=1
或
options kvm_amd nested=1

可能需要重新启动才能使更改生效。

以上是第一步，必须做，否则在后面安装会报错，后面在compute节点上还要做其他的设置

确定计算节点是否支持虚拟机的硬件加速
[root@compute ~]# egrep -c '(vmx|svm)' /proc/cpuinfo
>如果返回值为非0，则计算节点支持硬件加速，这通常不需要额外配置
如果返回值为0，则计算节点不支持硬件加速，必须配置libvirt为使用 QEMU 而不是 KVM。
编辑/etc/nova/nova.conf文件中的[libvirt]部分：
[libvirt]
virt_type = qemu

 

嵌套访客支持
要启用嵌套KVM的客人，计算节点必须加载 kvm_intel或kvm_amd与模块nested=1
[root@compute ~]# cat > /etc/modprobe.d/kvm.conf << EOF
options kvm_intel nested=1
options kvm_amd nested=1

将计算节点添加到cell数据库中
```

发现计算主机
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
```
添加新计算节点时必须在控制器节点上运行以注册这些新计算节点。
