Re: Xen: libvirt.libvirtError: An error occurred, but the cause is unknown

I enabled the log output in libvirt daemon, and there was one error message that appeared: error : libxlMakeDomBuildInfo:553 : unsupported configuration: emulator '/usr/lib/xen-4.11/bin/qemu-system-i386' not found

When searching the path with apt-file, there are no packages providing this file. I have qemu-system-x86-xen however: https://ubuntu.pkgs.org/20.04/ubuntu-universe-amd64/qemu-system-x86-xen_4... which provides /usr/bin/qemu-system-i386 Creating a symlink solved my issue: cd /usr/lib/xen-4.11/bin sudo ln -s /usr/bin/qemu-system-i386 . -> This seems to be an opened bug report on the libvirt Debian package (since 2016 !) https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=830307 -> Is there a way for libvirt to actually report meaningful errors in this case ?
