  said in Feature Request / Community Input – VM Boot Order & Delayed Startup: Hello everyone, I’m currently deploying a complete infrastructure for a client who previously used Hyper-V, where we could easily configure a VM boot order as well as startup delays between VMs. This ensured a clean sequence: XOA Domain Controller Application servers, etc. ⸻ What I have verified so far I contacted the official XCP-ng / XOA support, and they confirmed that this functionality does NOT currently exist, even on the paid (Premium) version of XOA. They also confirmed that: • There is no native way to set a boot priority in XCP-ng • There is no parameter such as order= or delay= in xe vm-param-set • XOA does not provide a UI for this either • The orchestration engine does not currently support dependent startup ⸻ What I’m asking the community Before I build something custom (scripts, hooks, cron jobs, etc.), I would like to know: Has anyone implemented a reliable way to: • Force a boot order for VMs • Introduce a configurable delay between VM startups • Ensure XOA starts first, then the Domain Controller, then other servers Is there perhaps: • A community script • A known workaround • A XenAPI trick • Or an unofficial feature hidden somewhere? ⸻ Environment • XCP-ng host • XOA Premium • ~5 VMs (DC, financial software, POS system, XOA itself, etc.) • Need clean deterministic startup order after host reboot or power outage ⸻ Any insight or community solutions would be greatly appreciated! This is something my client relied on in Hyper-V, so I’m trying to replicate the behavior in XCP-ng as cleanly as possible. Thanks in advance! Hello Olivier, vApp ??? What do you mean ?

  I hope someone will reply to my post here about how to check status on this but I believe I've resolved the main issue: I disabled and re-enabled the whole task itself yesterday and it ran this morning as scheduled.

  @SethNY you could even enhance this VM_LIST = with TAGs on VM, so that you manage the selection directly in XOA
• Infrastructure as Code

  Terraform, Packer or any tool to do IaC

  @cichy said in DevOps Megathread: what you need and how we can help!: Prioritization of VM startup AND shutdown sequencing! PLEASE - in the GUI (XO). So - without code - I can finally shutdown my servers accessing DB's prior to shutting down the DB server vm's themselves thereby saving myself from table corruption. @cichy In the past it was recommended to do this with an vApp and script. However this means editing the script or configuration file (if one’s created for the script). Which doesn’t make it as easy as the method, used by VMware ESXi for configuring the order and enabling the capacity. Xen Orchestra and/or XCP-ng could really do with an UI (and API) based method of setting up and managing the VM boot and shutdown order.
