The following image does not boot (or there is no connection to it), the status is blue (OK) in the GUI, but no connection to it is possible via the terminal. (tried different terminal solutions)
Does anybody have any experience with this (or a simmilar) release, what could be the difference to v7.10.2 which runs without any issues.
The templates have been updated according to the instructions in the cookbook.

and here's the template. Additional information

It's a different appliance, but I copied the files and used the same template anyway, but the router does not even boot (the status turns grey immediatalley)
According to GNS3 turning on UEFI boot is important, but I couldn't figure out yet how to do it in Eve NG
Here is ther guide (you can download the images from there to test e.g.: xrv9k-fullk9-x-24.3.1.qcow2)
https://gns3.com/cisco-ios-xrv-9000
************** Important Note ***********
From release version 24.4.1, the CML v2.9 IOS-XRv 9K 25.1.1 version and so on..., you must "Enable UEFI boot mode" option on the template configuration in order to boot this image.
