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

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.

Re: [ovirt-users] Import Virtual Machines From Web Admin GUI
Hi, you can try to exchange the keys shown here: https://www.ovirt.org/develop/release-management/features/virt/XenToOvirt/ if you want to use tcp without ssh look here: http://wiki.libvirt.org/page/Libvirt_daemon_is_not_listening_on_tcp_ports_although_configured_to basically you need to set * /etc/libvirtd.conf: listen_tls = 1 listen_tcp = 1 listen_addr = "0.0.0.0" * /etc/sysconfig/libvirtd: LIBVIRTD_ARGS="--listen" and restart libvirt but the no_verify you did works as well.

Re: [ovirt-users] Import Virtual Machines From Web Admin GUI
To answer my own question: as is often the case, perusing the commercial (RHV 4.0) documentation proved useful. The documentation is here: https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/virtual-machine-management-guide/612-exporting-and-importing-virtual-machines-and-templates However, I kept getting the error “Host key verification failed.: Connection reset by peer”. This despite having followed the official documentation on generating and copying keys, under Procedure 6.2.6 Importing a Virtual Machine from KVM. Then I found this article from July 2012 about a different (but similar) scenario: https://access.redhat.com/solutions/136463 What helped was the “alternative test” suggestion. Here is the URI I ended up using with success: qemu+ssh://root@MY_KVM_HOST/system?no_verify=1 Appending “no_verify=1” did the trick. It’s possible that adding hostnames and IPs to /etc/hosts would have also resolved this, but for something performed infrequently (importing a VM from another environment), modifying the URI is easier.
