this RFE is for completing the next RFE https://bugzilla.redhat.com/show_bug.cgi?id=1365411 which fixing the listing VMs issue in a case of Xen VMs with block device. Description of problem: - Currently, when trying to list available VMs to import from Xen using RHEV webadmin, if there is a block device disk configured on Xen, the list failed to load with the next vdsm.log error: jsonrpc.Executor/5::ERROR::2016-08-08 15:59:30,265::v2v::918::root::(_add_disk_info) Error getting disk size Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 915, in _add_disk_info vol = conn.storageVolLookupByPath(disk['alias']) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4596, in storageVolLookupByPath if ret is None:raise libvirtError('virStorageVolLookupByPath() failed', conn=self) libvirtError: cannot read dir '/dev/sdb': Not a directory - According to virt-v2v wiki, If the guest disks are located on a host block device, then the conversion will fail. see http://libguestfs.org/virt-v2v.1.html#xen-or-ssh-conversions-from-block-devices for a workaround. - It would be nice to have an ability to import VM with block device from Xen using virt-v2v workaround. Version-Release number of selected component (if applicable): rhevm-4.0.2.4-0.1.el7ev How reproducible: 100% Steps to Reproduce: 1. Add Block device to Xen 2. Using webadmin import dialog, enter Xen details and click "load" button. 3. Actual results: list failed to load. Expected results: using virt-v2v workaround, it should be possible to list source VMs and import them. Additional info: vdsm.log attached (issue occured at: 2016-08-08 15:59:30,265)
