Comment 4 Xianghua Chen 2017-01-09 05:01:05 UTC

Verified with packages:
libguestfs-1.32.7-3.el7_3.2.x86_64
qemu-kvm-1.5.3-126.el7.x86_64

Steps:
1. Prepare an rhel7 guest image on an Intel host (not on an AMD host),boot it.
2. In the guest vm：
Update the qemu-kvm version to ：
qemu-kvm-1.5.3-126.el7.x86_64
Install libguestfs：
libguestfs-1.32.7-3.el7_3.2.x86_64
3. 
# mkdir /tmp/whatever 
# cd /tmp
# curl -L -O http://download.lab.bos.redhat.com/devel/lkocman/efiboot.img
# LIBGUESTFS_BACKEND=direct guestmount -a efiboot.img -m /dev/sda /tmp/whatever -v

There is no such errors:
Probing EDD (edd=off to disable)... ok

4. ls whatever/
EFI

The image is mounted successfully.
