You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

Occasionally we will deploy a virtual instance into our KVM infrastructure and realize after the fact that we need more local disk space available. This is the process we use to expand the disk image. This process assumes the following:

• You're using legacy disk partitions. The process for LVM is similar and I will describe that in another post.
• The partition you need to resize is the last partition on the disk.

This process will work with either a qcow2 or raw disk image. For
