hi,
i'm trying to import a VM in oVirt from a KVM host that doesn't use storage pools. this fails with the following message in /var/log/vdsm/vdsm.log:
2017-07-05 09:34:20,513+0200 ERROR (jsonrpc/5) [root] Error getting disk size (v2v:1089) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 1078, in _get_disk_info vol = conn.storageVolLookupByPath(disk['alias']) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4770, in storageVolLookupByPath if ret is None:raise libvirtError('virStorageVolLookupByPath() failed', conn=self) libvirtError: Storage volume not found: no storage vol with matching path
the disks in the origin VM are defined as
<disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writethrough'/> <source file='/dev/kvm108/kvm108_img'/>
<disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/some/path/CentOS-7-x86_64-Minimal-1611.iso'/>
is this a virt-v2v or oVirt problem?
Well the stack trace is in the oVirt code, so I guess it's an oVirt problem. Adding ovirt-users mailing list.
Right, import of KVM VMs to oVirt doesn't involve virt-v2v. The current process gets the virtual size (i.e., capacity) and the actual size (i.e., allocation) of the volume using libvirt api that seems to rely on having the volume in a storage pool. So the process would need to be extended in order to support the case of having volumes that are not part of a storage pool.
