I think it’s based on the software what you use. I also get an error, but the vmware player import it without problem.
the name of your network card come from the driver, so different virtualization/settings cause different names. You can overwrite it.
How do you fix it?
If you check nginx in marketplace, you can go to the github page, where a big notice about the content pack is deprecated. Also another content pack’s link. https://github.com/graylog-labs/graylog-contentpack-nginx
The content pack was written when GL 3.0 was not available, so maybe it is normal if you can’t import a pack what not compatible with the new version.
If you have a bug in the software you should report to the developers.
“vmware player” is a toy to play at home. I’ve tried to import .owa into production environment based on licensed VMware ESXi hypervisor running on HPE DL380 Gen9. Not sure why we need sound card on server. Better to remove it from virtual hardware to avoid confusion.
Problem fixed by manual edit of 01-netcfg.yaml. Never has such issues with 2.4.x appliances.
Not a big issue, will be waiting for update compatible with v3.0
