I am using a debian 9 guest, hosted on a ESXi platform with nested virtualisation enabled. On this debian 9 guest when I run libguesfs-test-tool, it fails with an error: "qemu-system-x86_64: /build/qemu-DqynNa/qemu-2.8+dfsg/target-i386/kvm.c:1805: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed." Instead when I use a wrapper script and hook it with the env variable LIBGUESTFS_HV=/tmp/qemu.wrapper, things work fine, as in the script I just spawn the guest with the specific machine type pc-i440fx-2.1 over KVM. exec qemu-sys...

Hi, I am having issues with libguestfs; I am unable to mount a disk either from cli or via python bindings. This was working previously, but in order to have access to python3.5 I am trying to upgrade from Debian 8/Jessie to Debian 9/Stretch. Unfortunately the libguestfs error is getting in the way. Output of libguestfs-test-tool is attached as per libguestfs.org help. My current environment:

I don't believe there is a resolution yet, but please see: https://bugzilla.redhat.com/show_bug.cgi?id=1651021 https://lists.gnu.org/...
