GitHub user akrasnov-drv added a comment to the discussion: CloudStack starts misbehaving under minimal load
@rajujith First of all thank you, changing `execute.in.sequence.hypervisor.commands` to `true` significantly improved the state. Just now I started 38 VMs and they really started. Though I still saw kind of echo of the same problem. First 22 started fine, but then the rest were hanging in `Starting` state longer than I'd expect them to, e.g. ``` INFO VM.CREATE Started admin admin ROOT 20 Feb 2025 12:25:18 INFO VM.CREATE Completed admin admin ROOT 20 Feb 2025 12:27:07 ``` Almost 2 minutes, while the 1st ones started within 5-10 seconds ``` INFO VM.CREATE Started admin admin ROOT 20 Feb 2025 12:22:08 INFO VM.CREATE Completed admin admin ROOT 20 Feb 2025 12:22:13 ``` The problem may appear just on faster hardware, it may be some timing issue - I use 2x Xeon CPU physical servers. I mean, if you can't reproduce it on VM, you may need to try it on 2xCPU physical server. I'm using basic network now to exclude additional influences (e.g. VR), and I'm sure it will be no better on advanced network. Meanwhile I'll go further and try to add hosts and start more VMs. GitHub link: https://github.com/apache/cloudstack/discussions/10414#discussioncomment-12261955 ---- This is an automatically sent email for users@cloudstack.apache.org.
