[ovirt-users] Unable to import KVM VM from oVirt web-ui

[George Chlipala]

I am trying to import a VM from libvirt/KVM from the oVirt web UI
using the Virtual Machines > Import.   Here are the steps that I take.

- I select "KVM (via Libvirt)" as source
- I set the URI as "qemu+ssh://root@<hostname>/system".  I have
previously generated an SSH key for vdsm on the VM node and copied the
key to the libvirt host.
- I unlick "Require authentication" (using SSH keys)
- I select the proxy host as the VM host I setup vdsm with the ssh keys.
- Click "Load" to retrieve a list of VMs on the libvirt/KVM system
- Select the VMs to migrate and click the right arrow to move to the
right side of the wizard (Virtual Machines to Import)
- Click "Next"
- Select the proper storage domain, i.e. master storage domain.   (I
have tried both Preallocated and Thin-provisioned options for storage
and both fail to import.  I have also tried selecting "Clone" for the
VMs without success.)
- Click "OK"

oVirt seems to start the import, but then gives a message that it
failed to import.  I have gone through the vdsm.log and this seems to
be the relevant lines...
