Source: libguestfs
Version: 1:1.26.9-1
Severity: important
Dear Maintainer,
When trying to use virt-sparsify, I got the failure message:
libguestfs error: guestfs_launch failed
Running libguestfs-test-tool shows that libguestfs incorrectly detects
the CPU type / architecture. It mentions:
This kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot - please use a kernel appropriate for your CPU.
See below for the full libguestfs-test-tool output.
Both my CPU and my kernel are 64-bit (see below). Virtualisation is also
enabled and works fine - I frequently run both 32-bit and 64-bit virtual
machines (using: 'qemu-system-x86_64 -enable-kvm')
Both qemu-system-i386 and qemu-system-x86_64 are installed on my
system.
Kind regards,
Rogier.
(As an aside, on my system, libguestfs-test-tool does not seem to
terminate. After printing the messages below, it just hangs.
Similarly, virt-ls also seems to hang indefinitely, without
producing any output.)
