Issue There are no hosts available to migrate a VM. In the engine.log can be seen the reason: Candidate host 'XXX' (XXXXX) was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'Memory'Environment Red Hat Virtualization (RHV) 4.x ...
再次创建实例并检查日志。 查看一下nova-scheduler.log文件，并尝试找到如下一行： 。。信息nova.filters...
C# driver 3:All hosts tried for query failed (tried :10350: BusyPoolException'All connections to host :10350 are busy, 2048 requests are in-flight on each 10 connection(s)') 建议 请确保将max requests per connection设置为最小值 10,而不是优化connections per host。 请参阅代码示例部分。
There is no way to detect vSAN storage provider, If none of the hosts are available when vCenter Server starts. Note: vSAN storage provider cannot be recognized automatically even after host start working properly. Resolution To work around this issue, you have the following options. Initiate sy...
针对你遇到的“No valid host was found. There are not enough hosts available”错误,这是一个在OpenStack环境中创建虚拟机时常见的错误。下面我将根据提供的参考信息和你的提示,分点详细解答如何解决这个问题: 1. 确认错误信息的来源和上下文 这个错误信息通常表明OpenStack的调度器(nova-scheduler)在尝试为虚拟机...
实现“OpenStack No valid host was found. There are not enough hosts available.”的解决方法 1. 简介 在OpenStack中,当我们尝试创建一个虚拟机实例时,有时会遇到"OpenStack No valid host was found. There are not enough hosts available."这样的错误消息。这通常是由于OpenStack无法找到可用的主机来运行虚...
No valid host was found. There are not enough hosts available---openstack建虚拟机直接报错 一、问题现象: 二、解决思路: 1、查看计算节点的nova-compute 日志,发现如下日志: 2、查看nova-scheduler.log 3、进数据查看数据库表 4、尝试将compute节点从nova service-list中删除,并重新加入到集群中 5、...
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。
(1)控制节点和计算节点在部署前,需要在/etc/hosts里面对主机映射,并且后面不能轻易更改,否则会出问题! (2)mysql的连接数要调大!否则在操作过程中会由于mysql连接数过多而中断!比如设置mysql连接数为1000,mysql命令为set GLOBAL max_connections=1000;
