本文介绍了一种解决在OpenStack环境中创建云主机时遇到的500错误的方法。通过调整vinova.conf文件中的scheduler_default_filters配置为AllHostsFilter，并重启openstack服务，可以成功创建云主机。

openstack创建云主机报错500：

 

vi nova.conf


#scheduler_default_filters = AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter


scheduler_default_filters = AllHostsFilter


openstack-service restart

重新创建云主机即可

一套新起的OpenStack环境，在创建实例是发现报错。No valid host was found. There are not enough hosts available. 查看日之后发现 httpd有报错日志，日志指向horizon和nova。 [root@controller httpd]# cat error_log [Wed Dec 16 14:46:09.105540 2020] [:error] [pid 3409] INFO openstack_auth.views Loggi

 这个问题，可以先重启nova和neutron中的服务，再重启
 如果依旧出现这样的问题，可以中下面进行排查
 这个问题产生的很大原因有：1）计算节点的内存不足、CPU资源不够、硬盘空间资源不足造成的；将云主机类型规格调小点，发现就能创建成功。

对于一些刚接触OpenStack的新人，辛苦两天终于把OpenStack部署好了，建立实例时却失败了。这是一件很郁闷的事情。 大家试想一下，如果你准备启动一台物理服务器，如果服务器的CPU,内存,存储发生错误，在开机自检阶段就过不了，即意味着服务器挂掉，无法启动了。 同样，生成VM时常见的报错 ” No valid host was found. There are not enough hos

使用openstack创建虚拟机经常会遇到以下的这个错误 Error: No valid host was found. There are not enough hosts available. 从字面意思就可以看出是无法找到可用的host的资源来创建虚拟机。 再深一层的分析就是为什么会无法找到host主机呢？ 原因有多种，有可能是计算节点down了，但这个原因相信大家都能轻易的分析出来...
