Comment 6 for bug 2033957

It is not necessary to downgrade all packages.
What I did at the end was to exchanged the virtiofsd manually.
You can do this two ways, first and mostly better solution with an old version from the Ubuntu packages.
Second, download the new RUST based version from github. Second option has the requirement to update your guests as the parameters "flock and posix" are no longer required and supported.
