Setting RBD cache parameters for libvirt+qemu
...ings on a per-volume basis. Under libvirt-1.0.6 such VM's refuse to start:
error: Failed to start domain foo
error: unsupported configuration: ':' not allowed in RBD source volume name 'mypool/foo:rbd_cache_size=268435456:rbd_cache_max_dirty=134217728:rbd_cache_target_dirty=33554432:rbd_cache_max_dirty_age=5'
So my question is how do I control the cache settings now?
Thanks,
JN

You can set the cache mode with the cache attribute on the <driver>
element inside a <disk> [1]. This works for rbd with QEMU 1.2 or later.
