By passing root=UUID=... to supermin, we make the appliance boot process less sensitive to the non-deterministic process of scanning SCSI disks (of which much more to come). This patch should be tested alongside the supermin patch posted here: https://www.redhat.com/archives/libguestfs/2017-April/msg00174.html which in turn requires this supermin patch series:

The previous version did not prevent updating the balloon when it was being removed. There was an idea to update the stats in a separate work and cancel it after the config reset. But this does not seem to work. The code for updating the stats communicates with the host. IMHO, it should not run after the reset (flushing buffers). Therefore I decided to use a boolean value and a spin lock (inspired

Hello The current crypto_engine support only ahash and ablkcipher.

This patchset remove all algs specific stuff and now only process generic crypto_async_request. The requests handler function pointer are now moved out of struct engine and

Hi Jérôme, Ben and Jason, below is a series against the hmm tree which starts revamping the migrate_vma functionality. The prime idea is to export three slightly lower level functions and thus avoid the need for migrate_vma_ops callbacks.
