Hello,
I'm just trying to see if I can import from Oracle VM a bunch of VMs.
I'm trying from gui in 4.1 using XEN (via RHEL) as Source and in URI I put
this
xen+ssh://root@oracle_vm_host
I use one of my oVirt hosts as proxy (ovmsrv05 with ip 10.4.168.74)
From ovmsrv05 I verified I can ssh with public key and without
password
input to the oracle_vm_host
But when I click the "Load" button in oVirt GUI, in /var/log/secure of
Oracle VM Host I get a series of these messages:
Feb 23 15:22:25 oracle_vm_host sshd[25707]: Failed password for root from
10.4.168.74 port 54792 ssh2
Feb 23 15:22:25 oracle_vm_host sshd[25707]: Failed password for root from
10.4.168.74 port 54792 ssh2
Feb 23 15:22:25 oracle_vm_host sshd[25710]: Connection closed by 10.4.168.74
What I'm doing wrong here?
Thanks,
Gianluca

you need to add/run that as a vdsm user on ovmsrv05. Did you check the ssh via something
like "runuser -u vdsm”?

Ah... ok
I didn't realize that the import process is run by vdsm user on oVirt hosts.
Now I setup it for vdsm user but I get this in import window:
Failed to communicate with the external provider, see log for additional
details.
And this in webadmin events pane:
Failed to retrieve VMs information from external server
xen+ssh://root@oracle_vm_server
VDSM ovmsrv05 command GetVmsNamesFromExternalProviderVDS failed: End of
file while reading data: : Input/output error
Furher lines in vdsm.log (nothing inside import directory):

Host.getExternalVMNames failed (error 65) in 10.09 seconds (__init__:515)
Does the import phase need a libvirt daemon in target? In this case my
Oracle VM is 3.2.9 while probably libvirt (for integrating with Openstack)
has been introduced only in 3.4.1....
Or any chance to be able to communicate with Oracle VM Manager...?

Where can I find the commands it would run via xen+ssh against Xen to get
VMs and such...?

As Michal mentioned, virt-v2v uses libvirt to access VMs on Xen. So if
you have a ssh connection working then the following is the next thing
that should work:
virsh -c 'xen+ssh://root@oracle_vm_host' list --all
If it doesn't, you're out of luck.
After virt-v2v fetches the relevant information about VM it uses ssh
backend driver in Qemu to copy and modify the disks.
If you want to know more details, you probably should check the virt-v2v
sources.
