Hi Peter, thank you very much for this hint. Seems to work! :) But i also tried another switch: no_verify=1 The whole call: virsh -K0 -k0 migrate --copy-storage-inc --verbose --persistent --live testInstance qemu+ssh://testnode4:22/system?keyfile=/tmp/key-5ff4b02ca966c?no_verify=1?no_tty=1 So as you can see no_verify=1 no_tty=1 has been added. But still i receive The authenticity of host '[testnode4]:22 ([10.0.1.4]:22)' can't be established. ECDSA key fingerprint is SHA256:tcF31bWN6Gg8O5bMTkkusbcariPBWjGdLAP7WnfdqsM. Are you sure you want to continue connecting (yes/no/[fingerprint])? Should it not accept automatically this unknown fingerprint ? -- Mit freundlichen Gruessen / Best regards Oliver Dzombic Layer7 Networks mailto:info@xxxxxxxxxx Anschrift: Layer7 Networks GmbH Zum Sonnenberg 1-3 63571 Gelnhausen HRB 96293 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic UST ID: DE259845632 Am 03.01.21 um 13:33 schrieb Peter Krempa: > On Sat, Jan 02, 2021 at 14:25:32 +0100, Oliver Dzombic wrote: >> Hi, >> >> happy new year! >> >> Is there a way to tell libvirt to migrate an instance via qemu+ssh using >> a specific ssh key ? >> >> It seems libvirt will always try to use the .ssh/id_rsa private key. >> >> But i would like to somehow tell libvirt to use a specific private ssh >> key.
