behaviour. Non-technical users using, say, Windows (in full-screen
mode)
on a GNU/Linux desktop need to know that their HDD is full and they
must
free up space - not have the guest complain about cryptic HDD
errors and
failed writes (assuming the guest OS can even be trusted to do this).
Pausing the VM and notifying the user of no free host storage space is
also the same behaviour as other virtualization products, so this
might
already be the expected behaviour from the user's POV.
At the very least, I feel a switch to enable this behaviour would be
appropriate.
Having developed applications for memory-limited devices I agree that
an application must handle any cases, whether assumed common or not,
including out-of-memory situations. So qemu should always detect this
and handle it in some way.
Regarding the user's point of view described above, I concur that a
switch would be a good compromise. However given that someone using
CVS head is likely to read the mailing list and all other users
upgrading should read the release notes, this option should be the
default or otherwise exactly those users the feature is targeted at
will not use the switch! It's also more frontend-friendly not needing
an additional switch for mainstream users.
