[ovirt-users] Import Virtual Machines From Web Admin GUI

[Beckman, Daniel]

I indeed followed that procedure, including confirming I could SSH into the KVM host as user ‘vdsm’ without being prompted for a password. I had specified the host name of the KVM host, not the IP (though at one point I also tried the IP, with same results.) 

I was curious so on the KVM (source) host I added entries in /etc/hosts for all of the hypervisors in oVirt, along with the oVirt engine host for good measure (probably not necessary).

I tried another import, this time withouth the “no_verify=1” and it worked without error. 

Our internal DNS works – all of the hosts were able to correctly resolve addresses prior to me editing /etc/hosts. But I guess something in that process does not query DNS. 

Anyway, at least that’s a cleaner solution than removing verification. 

Thanks,
Daniel

    Hi,
    
    I'm sort of puzzled why you still saw "Host key verification failed" if
    you followed the procedure (or the steps described in [1]).

https://www.ovirt.org/develop/release-management/features/virt/XenToOvirt/

    
    Only thing I can think of is that you used IP of the KVM host during the
    procedure but then you used hostname in the URL (in import dialog).
    
    Another possible problem could be that there were two conflicting host
    keys in known_hosts file. But I believe adding "no_verify=1" would not
    help in this case.

Specifically, what user needs to trust what keys on which machines? The hypervisor hosts? The machine running the engine? Also, some examples of URI paths would be much appreciated.
