"command: sudo hostname testcl01-pool1-a9f476fd-slm2c && echo "testcl01-pool1-a9f476fd-slm2c" | sudo tee /etc/hostname err: inappropriate ioctl for device output: )"

Hello @med-jordan

I found the problem and it is unrelated to nutanix, in all case ssh connection is not managed by the rancher node driver but by the rancher-machine binary

In the rancher/machine:v0.15.0-rancher110 container they remove the ssh binary from the image (on purpose or not) so now the rancher-machine binary use a SSH Go native implementation as we can see in the log

SSH binary not found, using native Go implementation

And this is the reason why it broke against recent OS like centos-9-stream
