Wanlong Gao is correct that using libguestfs on a running
VM will (not maybe, *will*) cause disk corruption.

However you might want to look at libguestfs-live, which
involves installing a daemon in the VM that libguestfs talks to:

https://rwmj.wordpress.com/tag/libguestfs-live/
(Currently this only works for Linux VMs)

Also, if the VM is switched off, you can install a firstboot
script (as previously discussed).  This script runs when the
guest boots, and can install software etc.
