can not add hypervisor, alert "Got error: BAD_SSH_CREDENTIALS"

[hypozhong]

hi all,
i deploied two VMs, one of them is Dashboard（192.168.10.107）, the other is Hypervisor（192.168.10.108）, and the Dashboard and vdi-agent worked normal.

and then i try to add hypervior, but it unormal, an it reported error, like this PIC:

I checked the log in the /var/log/apache2/error.log, like this PIC,

then i try to check the key-free login,command like :ssh -i /var/hyper_keys/id_rsa VDI@192.168.10.108，
it logged in sucessfull

this is the /var/log/auth.log records.

my question is , the dashborad server connect to the hypervisor by Key-free login, this way is OK by command-line, why can not add hypervisor........

This was asked many times before. Your webserver user cannot read key files. Change permissions.

thank u @Seitanas
I am not very clear about the current allocation of privileges.

1. what is the dashboard process user,root or VDI
2. what is the vdi-agent process user?
3. what the permissions of rhe folder /var/hyper_keys

Please give me a clear idea. thanks a lot

chown +r /var/hyper_key
and then add the hypervisor machine successfull

I have been trying to solve the problem with ssh2_auth_pubkey_file but it does not solve.
I have tried the forum solutions, but have not yet managed to add the new hypervisor.
Can someone help me, thanks

Finally got it working, changed the permissions of the privkey and public key in /var/hyperkeys/ to 644.
