Comment 0 for bug 2000186

When upgrading from 0.8.8-1ubuntu1 to 0.8.8-1ubuntu1.22.04.1, dpkg fails.
Based on the error messages, I believe this to be due to running under a paravirt kernel.

Package does not seem to offer a way to disable without uninstalling, which also forces the removal of the meta-package ubuntu-server.

Manually running multipathd to obtain verbose output indicates this is most likely due to missing kernel module:
