I just received some information I would like to share with you:
The devs are still working on the Qemu LizardFS support. However, there are two things to consider:
Because of these two points, there might be a closed alpha test on the Qemu integration. The module requires compiling QEMU from sources with the LizardFS block device driver.
So far, I have received no information if and how you could apply for such a test. However, I guess it is positive to know that things are still going forward.
