I was wondering if there is a way to use encrypted filesystem inside a domU ? I tried to look around and whatever guides i found required me to patch the kernel.

I also found about cryptoloop, however when i try to use it inside domU, it gives me an error

losetup -e cryptoloop /dev/loop0 /dev/sda2
Password:
ioctl: LOOP_SET_STATUS: Invalid argument

I also tried various combinations

losetup -e des /dev/loop0 /dev/sda2
losetup -e aes128 /dev/loop0 /dev/sda2
losetup -e aes-256 /dev/loop0 /dev/sda2

However all the above result in the same error.

How should i setup the encrypted fs ? Any help would be appreciated.
