Unless I'm missing something, these three patches are
already included in libguestfs 1.14.

Verified this bug on libguestfs-1.16.2-1.el6

Version-Release
libguestfs-1.16.2-1.el6
virt-v2v-0.8.7-4.el6.x86_64
rubygem-virt-p2v-0.8.6-2.el6

Steps：
1. convert CCISS-rhel6.2-x86_64 to rhevm successfully.
2. import CCISS-rhel6.2-x86_64 to rhevm successfully.
3. start the guest on rhevm successfully.
4. check some files on source and target.

Cause:
CCISS devices have paths (eg. "/dev/cciss/c0d0p1") which libguestfs didn't understand.

Consequence:
When virt-p2v converted a physical machine that uses CCISS devices to run in a VM, libguestfs inspection would fail because it didn't understand the /etc/fstab file containing these paths.

Fix:
libguestfs has been updated so that it understands /dev/cciss/* paths appearing in guest /etc/fstab.

Result:
virt-p2v is now able to successfully convert these guests.
