Expose QEMU's 9pfs 'fmode' and 'dmode' options via attributes on the 'filesystem' node in the domain XML. These options control the creation mode of files and directories, respectively, when using accessmode=mapped. QEMU defaults to creating files with mode 0600 and directories with mode 0700.

This patch still mixes the XML bits with the qemu implementation.

Compilation of the tree doesn't pass 'virschematest' after this patch as you are adding the RNG schema after adding the XML.

You are missing a change to qemuxml2argvtest to actually invoke also the testing of the command line formatter ...
