I could reproduce customer's problem Packages: rhv:4.1.3-0.1.el7 vdsm-4.19.20-1.el7ev.x86_64 virt-v2v-1.36.3-6.el7.x86_64 libguestfs-1.36.3-6.el7.x86_64 Steps: 1.Prepare a guest which is not listed storage pool # virsh dumpxml avocado-vt-vm1 .... <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/root/RHEL-7.3-x86_64-latest.qcow2'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> ..... 2.Try to import this guest in rhv4.1 from KVM host but failed to import the guest as screenshot and get error info from vdsm.log .... 2017-07-07 14:41:22,176+0800 ERROR (jsonrpc/6) [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 4555, in storageVolLookupByPath if ret is None:raise libvirtError('virStorageVolLookupByPath() failed', conn=self) libvirtError: Storage volume not found: no storage vol with matching path '/root/RHEL-7.3-x86_64-latest.qcow2' .... 3.Try to convert this guest to rhv by virt-v2v on v2v conversion server,could import the guest from export domain to data domain on rhv4.1 after finishing conversion # virt-v2v avocado-vt-vm1 -o rhv -os 10.73.131.93:/home/nfs_export [ 0.0] Opening the source -i libvirt avocado-vt-vm1 [ 0.0] Creating an overlay to protect the source from being modified [ 0.4] Initializing the target -o rhv -os 10.73.131.93:/home/nfs_export [ 0.7] Opening the overlay [ 6.1] Inspecting the overlay [ 13.8] Checking for sufficient free disk space in the guest [ 13.8] Estimating space required on target for each disk [ 13.8] Converting Red Hat Enterprise Linux Server 7.3 (Maipo) to run on KVM virt-v2v: This guest has virtio drivers installed.
