Migration via qemu+ssh using a given private ssh key possible ?

[Oliver Dzombic]

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 ?
