Package: linux-image-6.0.0-6-cloud-amd64
Version: 6.0.12-1
Severity: wishlist

Hi,

I already talked with Bastian on #debian-devel about this, but that was
inconclusive, so I'm taking it to email.

I request adding support for the 9p filesystem to the cloud image. While
Bastian pointed out that the primary use case of cloud kernels is AWS,
Azure and GCE, I think that these kernels should be generally useful in
virtualisation environments such as kvm. As far as I understand it, they
significantly reduce the size by removing hardware drivers that are not
usually available in virtualised environments.

While none of the mentioned cloud providers provide 9p filesystems to
their guests, the -virtfs option to kvm/qemu is by far the simplest way
to share a host filesystem with a virtual machine. The cloud kernel
image already covers virtiofs, but virtiofsd comes with significant
additional complexity on the host - most significant is the requirement
for being run as root. Given the similarity of virtiofs and 9p, the
latter should be included as well.

Adding 9p would increase the Installed-Size by about 600kb, i.e. less
than 0.5%.

Of course, one can always install the non-cloud kernel to use 9p.

Hi

This bug was filed for a (very) old kernel or the bug is old itself
without resolution. Maybe it was for a feature enablement which nobody
acted on. We are sorry we were not able to timely deal with this issue.
There are many open bugs for the src:linux package and thus we are
closing older bugs where it's unclear if they still occur in newer
versions and are still relevant to the reporter. For an overview see:
https://bugs.debian.org/src:linux .

If you can reproduce your issue with

- the current version in unstable/testing
- the latest kernel from backports

or, if it was a feature addition/wishlist and still consider it
relevant, then:

Please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Please try to provide as much fresh details including kernel logs where
relevant. In particular were an issue is coupled with specific hardware we
might ask you to do additional debugging on your side as the owner of the
hardware.

Regards,
Salvatore
