Azure并行创建多个虚拟机失败

Question

我正在使用这个示例https://github.com/azure-samples/compute-java-manage-virtual-machines-in-parallel

它可以很好地与VM编号5配合使用。但是，如果指定VM数量为17或33，则会失败，异常数量等于无法创建的VM数量(其中一些已创建)。没有返回好的错误消息。可能的错误是什么？

我得到的日志是这样的

[RxIoScheduler-22] INFO com.microsoft.azure.management.compute.VirtualMachines createOrUpdate - <-- 409 Conflict https://management.azure.com/subscriptions/.../resourceGroups/rgcoppc3834913a3950/providers/Microsoft.Compute/virtualMachines/VM-19?api-version=2016-04-30-preview (1815 ms, 195-byte body)

堆栈跟踪示例(33个虚拟机，其中一些未创建)：

Answer 1

Java Azure SDK在提供有意义的错误消息方面应该更有帮助。

在Web Azure界面中，转到“事件”页面。在那里，您可以找到故障日志。那里的消息仍然不是很有帮助，但谷歌为他们提供了帮助。

我发现每个地区和/或订阅都有配额https://docs.microsoft.com/en-us/azure/azure-subscription-service-limits

下面是典型的错误：https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-manager-common-deployment-errors#quotaexceeded

您应该发出支持请求以增加配额：https://blogs.msdn.microsoft.com/girishp/2015/09/20/increasing-core-quota-limits-in-azure/
