Hello everyone, we switched from using qemu-img from CentOS 7.x to qemu-img-ev from the Virt SIG several months ago, to allow us to generate Hyper-V images. My attempts to build Vagrant images are failing the automated tests since the beginning of July, apparently due to corrupt filesystems. I see XFS metadata corruption in the CentOS 7 images when using qemu-img-ev, as well as ext4 superblock corruption in the CentOS 6 images.[1] The distro installer runs just once and the resulting disk image is converted by Image Factory to different formats, depending on the virtualization target. Since the VirtualBox images are working as expected, while the libvirt images don't even boot due to filesystem corruption, I would assume that the installation produces a valid image, but the conversion of the disk images for libvirt-kvm fall prey to bugs in qemu-img-ev and the stock qemu-img. If anyone has the possibility to test with VmWare or Hyper-V, please write me off-list. I noticed that qemu-img-ev is at version 2.1.2, while Debian Stable has version 2.8 and Fedora 28 has version 2.11. Maybe such bugs, if real, were already fixed upstream - would it be possible to use a newer version than what qemu-img-ev provides? We reverted to using the EL7 qemu-img, but this still produces broken libvirt images and wețd have to drop the Hyper-V images as well. Any help or suggestions are appreciated.
