[Qemu-devel] [Bug 1838312] Re: Qemu virt-manager Segmentation fault

[Hans Peter <1838312@bugs.launchpad.net>]

I removed in "/usr/lib/python3/dist-packages" the file
"apport_python_hook.py"

so the output of # PYTHONDEVMODE=1 virt-manager --no-fork

is now:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/libvirt.py", line 24, in <module>
    import cygvirtmod as libvirtmod
ModuleNotFoundError: No module named 'cygvirtmod'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager", line 20, in <module>
    from virtinst import util
  File "/usr/share/virt-manager/virtinst/__init__.py", line 26, in <module>
    from virtinst import util
  File "/usr/share/virt-manager/virtinst/util.py", line 15, in <module>
    import libvirt
  File "/usr/lib/python3/dist-packages/libvirt.py", line 28, in <module>
    raise lib_e
  File "/usr/lib/python3/dist-packages/libvirt.py", line 20, in <module>

Bug description:
  Hi!

  I installed all these packages:

  sudo apt install qemu
  sudo apt install ipxe-qemu-256k-compat-efi-roms libspice-server1 libbluetooth3
  sudo apt install libbrlapi0.6 libcacard0 libfdt1 libusbredirparser1 libvirglrenderer0 libxen-4.9 libxenstore3.0
  sudo apt install cpu-checker ibverbs-providers ipxe-qemu libibverbs1 libiscsi7 libnl-route-3-200 librados2 librbd1 librdmacm1 msr-tools sharutils
  sudo apt install qemu-block-extra qemu-system-common qemu-system-data qemu-system-gui qemu-utils
  sudo apt install --no-install-recommends qemu-kvm qemu-system-x86
  sudo apt install libauparse0 ebtables gir1.2-gtk-vnc-2.0 gir1.2-libosinfo-1.0 gir1.2-libvirt-glib-1.0 gir1.2-spiceclientglib-2.0 gir1.2-spiceclientgtk-3.0 libvde0 libvdeplug2 libgovirt-common libgovirt2 libgtk-vnc-2.0-0 libgvnc-1.0-0 libosinfo-1.0-0 libphodav-2.0-0 libphodav-2.0-common libspice-client-glib-2.0-8 libspice-client-gtk-3.0-5 libusbredirhost1 libvirt-clients libvirt-daemon libvirt-daemon-driver-storage-rbd libvirt-daemon-system libvirt-glib-1.0-0 libvirt0 osinfo-db python3-libvirt python3-libxml2 spice-client-glib-usb-acl-helper vde2 vde2-cryptcab virt-viewer virtinst virt-manager

  without the i386 packages for Qemu because I want only 64 bit.

  I installed all these packages without error, but when I run

  # virt-manager

  Output: ...shows me:

  Segmentation fault

  
  My hardware is 100% ok.
  Maybee a broken lib?


  How can I fix that?
