@olivierlambert +1 For creating vApps GUI in XO Reason: I recently had this configuration: VM1 - Delay 90 Seconds VM2 - Delay 100 Seconds VM3 - Delay 0 Seconds The VM3 instead of starting first, always starts last without fail. One difference I noticed is that VM3 is UEFI vs VM1 & 2 being in BIOS mode. I read elsewhere in the forum that vApps is the only reliable way to have an order. Maybe if we can somehow ensure that delay works, vApps will become less significant ?

@Alexander-0 Thanks! I'll compare this to my original notes (still from Xenserver 6 era, but used on 7 and 8 too)
