Description of problem:
Before convert, the disk size is 6G, after convert, the disk size show 3.3T when execute command "fdisk -l".

Version-Release number of selected component (if applicable):
virt-v2v-0.7.1-2.el6.x86_64
libguestfs-winsupport-1.0-5.el6.x86_64
libguestfs-1.7.17-12.el6.x86_64
libvirt-0.8.7-5.el6.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Convert xen guest to RHEV
# LIBGUESTFS_TRACE=1 virt-v2v -ic xen+ssh://10.66.72.123 -o rhev -osd 10.66.90.115:/vol/v2vrwu1/xen_export rhel5u6-64b-fv-raw-xen > /root/rhel5u6-64b-fv-raw-xen_convert.log 2>&1
2. After conversion, import it and then run it
3. Execute command "fdisk -l".


Actual results:
[root@dhcp-93-104 ~]# fdisk -l
