strange, you could check with debug log mode, there it outputs the paramiko related logging for setting up the ssh session too. |

no i don't think another key is used ssh -vvv -i /root/.ssh/id_rsa [email protected] debug1: Authentication succeeded (publickey) and when I cd to the directory for my backup can see this file |

run virtnbdbackup with "-v" option to see the paramiko logging output. |

already run it with --verbose and for the log from my remote server that's when I run backup command and when I run ssh -v -i /root/.ssh/id_rsa [email protected] : pam_unix(sshd:session): session opened for user root by (uid=0) the session is opened and not disconnect |

idk sorry, you must check for what reason the ssh connection is denied, maybe run sshd on remote system in debug mode to get more info. Maybe ssh connection attempts to use some key authentication algorithms that are disabled. Its all default in paramiko, no special code in virtnbdbackup that i would know to cause such an issue Also i cant reproduce it, it works fine on all my systems (debian bookworm) involved. If executed with -v i, on my system, get an detailed information on what is going on on the paramiko layer: i wonder why that output is missing at your system. It should clearly show more informations here. Can you connect remote sytem via virt-manager and ssh transport? What happens if you point "virsh" to the qemu+ssh uri you specified, as in:
from the remote? |

why does the system resolve to localhost.localdomain?
are you sure youre connecting to the right system here?? it seems to try to use both id_rsa and id_cdsa but fails:
I assume both keys dont have an password set? |
