The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

v2 was here: https://www.redhat.com/archives/libguestfs/2020-March/msg00154.html v3: - Micro-optimize tmpdir. - Quote $disk in default command shell fragment. - Don't redirect mkfs output to /dev/null. Instead use exec </dev/null >/dev/null before the shell fragment. We may want to do this in other places where we run external shell scripts, or more generally for all

Hi ,all : thanks for helping me ! I am using libguestfs-1.28.1 on ubuntu 12.04 to manage vm disk created by KVM. I downloaded libguestfs-1.28.1.tar.gz ,and then executed (1) ./autogen.sh (2) ./configure (3) make (4) make check .there is the error. /usr/Libvmi/libguestfs-1.28.1/run --test guest-aux/make-fedora-img.pl md_create: feature 'mdadm' is not available in this

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be

https://bugzilla.redhat.com/show_bug.cgi?id=836710 https://bugzilla.redhat.com/show_bug.cgi?id=836913 There are at least two related bugs going on: (1) Linux sync(2) system call doesn't send a write barrier to the disk, so in effect it doesn't force the hard disk to flush its cache. libguestfs used sync(2) to force changes to disk. We didn't expect that qemu was caching anything
