Are you able to install xposed on Android 4.4?
I ask, because i get these messages when i try to install xposed without using a custom kernel image.

What is your base image? (Google images or something else)

The message itself does not make any sense to me, other than the logging mechanism (which doesn't work for me) there is nothing that needs to mount a filesystem.

Hi, it's been 2.5 years since you answered so I thought to ask again.

I'm using the Nox emulator, xposed version 89 and android 5.1.1
when I look the look on xposed installer this is what I get:
09-05 11:28:55.789 I/Xposed ( 1468): -----------------

I don't get any information about the API hooking of the droidmon module.. I'm looking at the wrong place?
and when I look and the 'adb logcat -d' output there is a line that says:
W/PackageManager( 1758): Not granting permission android.permission.MOUNT_UNMOUNT_FILESYSTEMS to package com.cuckoodroid.droidmon (protectionLevel=18 flags=0x8be46)

it might be the problem? what to do?
thank you.
