it definitively happened when upgrading to 9.4.1 from a spread of earlier versions. but to be honest i havent tracked if it happened to 9.4.2.
i run 20~ customer xcp-ng installations most of them 9.4.1 for now since the CTX692748 security fix and was thinking to skip 9.4.2 but some newer guests of the customer servers is on that version.
@KPS i have seen the same on WS 2022. when upgraded to version 9.4.1 and 9.4.2 create a new nic and then the old disappears. and if static IP is set it also loses the gateway for the ip setting in some cases.
Yeah understandable! okay i will test that in the lab before production.
Thank you Oliver for fast reply and keep up the good work 
.
not directly support tape "yet" is there any roadmap or is it in the future?
I guess when veeam support is live it will be posible since support is in veeam for tape storage but i rather stick to just one backup solution in this case XOA to streamline the whole proccess.
you say our linux program can you point me to any documentation on this?
Thank you Oliver!
