ssh -i id_rsa  youruser@fedorahost

this is quite strange; because the same keyfiles works from another Linux [not 
Fedora]

what's causing this strange behaviour?
In cases like this I run ssh with debug option to see what is happening.
Try ssh -v and see of the output help point to the problem.
Adding more -vvv outputs more debug details.

ssh -vvv didn't really give any useful hints; I guess the problem is NOT caused by just the key;

I found this: https://kcore.org/2023/03/27/ssh-unifi-fedora-37/

(the key would be suitable: it is a RSA 2048 bit key)

but I don't want to set the crypto policies on the Fedora VM to LEGACY

for connecting to the Fedora VM I created an ED25519 key
(https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_keymanagement)

and now it works: the RSA key to the other Linux VMs and the ED25519 key just to the Fedora VM;

but quite strange phenomen;
