    qemu-img: Add cache command line option · 661a0f71
    Federico Simoncelli authored
    qemu-img currently writes disk images using writeback and filling
    up the cache buffers which are then flushed by the kernel preventing
    other processes from accessing the storage.
    This is particularly bad in cluster environments where time-based
    algorithms might be in place and accessing the storage within
    certain timeouts is critical.
    This patch adds the option to choose a cache method when writing
    disk images.
