Hello,
I _might_ be doing something wrong when calling KSPSetFromOptions/KSPSetUp, but still, am I supposed to get this kind of error?
[0]PETSC ERROR: No support for this operation for this object type
[0]PETSC ERROR: KSP gmres does not support PRECONDITIONED with RIGHT

If not, I’ll try to send a MWE (it basically depends on where I set the option -ksp_pc_side right).

I believe its telling you that it cannot display the preconditioned residual with right preconditioning, which is true.
Are you requesting both?
