Daniel P. Berrange eed968607d hw/9pfs: Remove O_NOATIME flag from 9pfs open() calls in readonly mode ... When 2c74c2cb4b added support for the 'readonly' flag against 9p filesystems, it also made QEMU add the O_NOATIME flag as a side-effect. The O_NOATIME flag, however, may only be set by the file owner, or a user with CAP_FOWNER capability. QEMU cannot assume that this is the case for filesytems exported to QEMU. eg, run QEMU as non-root, and attempt to pass the host OS filesystem through to the guest OS with readonly enable. The result is that the guest OS cannot open any files at all. If O_NOATIME is really required, it should be optionally enabled via a separate QEMU command line flag. * hw/9pfs/virtio-9p.c: Remove O_NOATIME Acked-by: M.
