Error using guestmount to mount windows qcow2 image

my os is centos 7.4

root@wllabs:/home/wllabs/instances/image2016$ cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

kernel version: 3.10.0

root@wllabs:/home/wllabs/instances/image2016$ uname -r
3.10.0-693.5.2.el7.x86_64

Here is my mount command and error prompt， use guestmount -m /dev/sda1

root@wllabs:/home/wllabs/instances/image2016$ guestmount -a win2016 --ro -m /dev/sda1 /mount libguestfs: error: mount: unsupported filesystem type guestmount: '/dev/sda1' could not be mounted. guestmount: Did you mean to mount one of these filesystems? guestmount: /dev/sda1 (ntfs) guestmount: /dev/sda2 (ntfs)

here is use guestmount -m /dev/sda2

root@wllabs:/home/wllabs/instances/image2016$ guestmount -a win2016 --ro -m /dev/sda2 /mount libguestfs: error: mount: unsupported filesystem type guestmount: '/dev/sda2' could not be mounted. guestmount: Did you mean to mount one of these filesystems? guestmount: /dev/sda1 (ntfs) guestmount: /dev/sda2 (ntfs)

-m /dev/sda report error , so i use -i to guestmout, but also error

root@wllabs:/home/wllabs/instances/image2016$ guestmount -a win2016 --ro -i /mount guestmount: no operating system was found on this disk If using guestfish '-i' option, remove this option and instead use the commands 'run' followed by 'list-filesystems'. You can then mount filesystems you want by hand using the 'mount' or 'mount-ro' command.

If using guestmount '-i', remove this option and choose the filesystem(s) you want to see by manually adding '-m' option(s). Use 'virt-filesystems' to see what filesystems are available.

If using other virt tools, this disk image won't work with these tools. Use the guestfish equivalent commands (see the virt tool manual page).

the libguestfs-winsupport and ntfs are all installed.

root@wllabs:/home/wllabs/instances/image2016$ rpm -qa | grep winsupport
libguestfs-winsupport-7.2-2.el7.x86_64
root@wllabs:/home/wllabs/instances/image2016$ rpm -qa | grep ntfs
ntfs-3g-devel-2017.3.23-1.el7.x86_64
ntfsprogs-2017.3.23-1.el7.x86_64
ntfs-3g-2017.3.23-1.el7.x86_64

I'm noticing the same behavior..

According the documentation, this is normal behavior. They removed ntfs support starting from RHEL/CentOS 7.3. More info on: http://libguestfs.org/guestfs-faq.1.html#mount:-unsupported-filesystem-type-with-ntfs-in-rhel-7.2

It is possible to compile your own libguestfs which supports ntfs, but this is not supported. I haven't tested it yet, but this thread mentions the steps. https://www.redhat.com/archives/libguestfs/2016-February/msg00145.html

I hope this helps since this is my first post. :-)

Kind regards,

Jeff
