This is neither an issue with aptitude nor a bug:

As the output says, "zfsutils : Conflicts: zfs-fuse", but libguestfs-tools depends on libguestfs0 which depends on zfs-fuse.

So zfsutils and libguestfs-tools can't be installed at the same time. Which is exactly what aptitude argued about.

Closing as invalid.

I didn't wanted to bring this up, but that is not the case in Centos. there i can install zfs and libvirtguestfs both without issues.

in the above comment there was a typo, and it's not letting me fix it. what i meant was i can install and use zfs and libguestfs-tools both on Centos.

Which version of libguestfs?

In Debian libguestfs, the zfs dependency has been split out into a separate package (libguestfs-zfs). So it's likely that Ubuntu needs to sync with the Debian package.

This is technically not an issue with aptitude, which is doing what it's supposed to, but this is ABSOLUTELY a bug.

zfsutils provides all the code that libguestfs0 is looking for, but the libguestfs0 package is not configured to accept anything but the installation of zfs-fuse, bar none, full stop. Which is a bug. You don't necessarily need any ZFS at all to be running libguestfs0, and you *absolutely* don't need zfs-fuse, which is essentially a dead project, even if you do want to run ZFS and libguestfs-tools.

This should be fixed by changing the dependencies in libguestfs0. For one, ZFS shouldn't be a hard dependency at all, it should be a recommend. For another, whether a depend or a recommend, it should be 'zfs-fuse | zfsutils', not merely 'zfs-fuse' as it is now.

In the meantime, workaround for those of us who aren't package maintainers is here:

http://jrs-s.net/2015/05/13/libguestfs0-and-zfs-on-linux-in-ubuntu/

TL;DR edit the deb, remove the ill-considered dependency, done (at least until the next update puts it right back again).
