[libvirt] [PATCH v1 0/2] Fix qcow2 fully allocated filesystem objects.
From: Wim ten Have <wim.ten.have(a)oracle.com>
When tools like virt-install request to create a fully allocated
filesystem object storage by setting the parameter sparse=no, libvirt
doesn't allow that to happen for qcow2 formatted files.
Regardless of its XML instuction request libvirt always targets its
filesystem object storage with preallocation=metadata if format=qcow2
is in effect. This results in sparse files which could cause problems
since total image storage potentially can overrun actual filesystem
available space.
(NOTE: This is a RESEND holding corrected cover letter and commit
messages / Subject headers.)
Wim ten Have (2):
storage: extend preallocation flags support for qemu-img
tests: add qemu-img test for preallocation=falloc
