I download libguestfs from github and fetch to the *origin master*. I tried to build libguestfs in my own linux distro and I followd the http://libguestfs.org/guestfs-building.1.html#using-a-prebuilt-binary-appliance to replace with supermin I download the appliance-1.30.1.tar.xz and appliance-1.30.1.tar.xz.sig and extract the tarball to /home/user/appliance and export

So it didn't make any noticable difference in my test. I wonder if the test guest I'm using (Fedora 32 using dracut) doesn't use parallel compression? However I don't think it can cause a problem and it seems obvious that it could benefit some cases. Rich.

Currently the tests fail on x86 with recent kernels: FAIL: test-255-disks.sh This confused me for a while because our other test program (utils/max-disks/max-disks.pl) reports that it should be possible to add 255 disks. Well it turns out that the default amount of appliance memory is sufficient if you're just adding disks, but if you try to add _and_ partition those disks there's
