Nikita, Please take a look at the attached patch. I have rewritten it a little, and only lightly tested it. Rich.

virt-sparsify shouldn't die if sparsifying a filesystem that contains read-only LVs. https://bugzilla.redhat.com/show_bug.cgi?id=1185561 I thought about trying to make the LV writable temporarily, but I suspect that if the sysadmin has made the LV read-only, then they probably did it for a reason, so we shouldn't touch it.

DAX is explained in detail here: https://lwn.net/Articles/610174/ This patch adds support to supermin for using a DAX root filesystem. The corresponding libguestfs patches will be posted shortly once I've tested them a bit more. This requires qemu >= 2.6. Unfortunately it's not really a win for a few reasons: - Requires enabling ACPI, which slows everything down by hundreds of

Require the root= parameter is passed to specify which root (apppliance) to mount. Libguestfs has done this since 2012. The other two patches are small code refactorings in the init program. Rich.

https://bugzilla.redhat.com/show_bug.cgi?id=1564983 Because Mount.mount_vfs was declared with the wrong type signature it could never be called correctly from outside the daemon. The root cause of this problem is that the generator doesn't generate the type signatures automatically (which it could do, and fairly easily). Therefore there are probably other similar bugs waiting to be found.
