Although a guest will be imported correctly into RHEV and will run correctly, attempting to create a template from it will result in the following error in RHEV-M's Events log: Failed to complete creation of Template Test from VM rhel6. vdsm.log contains: e7c2c09e-e224-4ba0-a551-67015f1b677e::ERROR::2011-02-09 11:24:12,041::image::738::Storage.Image::(copy) Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/image.py", line 733, in copy dstVol.extend(newsize) File "/usr/share/vdsm/storage/blockVolume.py", line 300, in extend lvm.extendLV(self.sdUUID, self.volUUID, sizemb) File "/usr/share/vdsm/storage/lvm.py", line 904, in extendLV raise se.VolumeGroupSizeError("%s/%s %d > %d" % (vgName, lvName, int(size) * MEGAB, free_size)) VolumeGroupSizeError: Volume Group not big enough: ('b00de9fd-25e4-45f5-95b5-8292921395c4/b0a7664a-30a2-4037-bc57-4d63a4d51147 1099511627776 > 101267275776',) earlier in the logs reveals: Thread-639::INFO::2011-02-09 11:24:11,128::volume::628::Storage.Volume::(getInfo) b00de9fd-25e4-45f5-95b5-8292921395c4/e6fa620e-535f-4912-bbc0-a4b8d43faac0/9d4040b9-22d6-4602- 88d1-c9f670cf3183 info is {'status': 'OK', 'domain': 'b00de9fd-25e4-45f5-95b5-8292921395c4', 'truesize': '2147483648', 'voltype': 'LEAF', 'uuid': '9d4040b9-22d6-4602-88d1-c9f6 70cf3183', 'parent': '00000000-0000-0000-0000-000000000000', 'format': 'RAW', 'description': 'Exported by virt-v2v', 'children': [], 'ctime': '1297250566', 'disktype': '1', 'l egality': 'LEGAL', 'mtime': '1297250567', 'capacity': '1099511627776', 'apparentsize': '2147483648', 'type': 'PREALLOCATED', 'image': 'e6fa620e-535f-4912-bbc0-a4b8d43faac0', ' Note that capacity == apparentsize * 512, and the template is attempting to create a new volume of size <capacity>. I believe that this is caused by incorrect units for SIZE in the .meta file for the volume originally created by virt-v2v. virt-v2v currently assumes units of bytes. Trial and error suggests the units should be 512 byte sectors. I am currently looking for confirmation of this: http://post-office.corp.redhat.com/mailman/private/rhev-devel/2011-February/msg00106.html
