For some reason the dedicated anchor 'msize' does not work though: https://wiki.qemu.org/Documentation/9psetup#msize Not sure whether that's a wiki installation problem? When I view the wiki source, it looks like it is showing some errors there. v1->v2: * Updated commit log message to make it more clear why the client cannot auto pick a good value for 'msize'. * Added a web link to the log message, pointing to the appropriate QEMU wiki page which explains the 'msize' issue in detail.
