Hi,

From the logs it looks like a permission issue: ssh-keygen: /proc/self/fd/0: Permission denied Cannot generate ssh pubkey out of certificate

Can you please also attach vdsm and messages logs from the host. Sandro, maybe you will have more insights about this error? Regards, Maor On Tue, Aug 30, 2016 at 5:50 AM, 554450306@qq.com <554450306@qq.com> wrote:

Did you try to remove the Host and reinstall it, can you please attach the engine and VDSM logs.

I found an email which might help if that is indeed the same issue: http://lists.ovirt.org/pipermail/users/2014-November/028870.html
