[PATCH v2 1/2] conf, docs: Add qcow2 cache configuration support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Random write IOPS will drop dramatically if qcow2 l2 cache could not
cover the whole disk. This patch gives libvirt user a chance to adjust
the qcow2 cache configuration.

Three new qcow2 driver paramters are added. They are l2-cache-size,
refcount-cache-size and cache-clean-interval.

The following are from qcow2-cache.txt.
The amount of virtual disk that can be mapped by the L2 and refcount
caches (in bytes) is:
disk_size = l2_cache_size * cluster_size / 8
disk_size = refcount_cache_size * cluster_size * 8 / refcount_bits

The parameter "cache-clean-interval" defines an interval (in seconds).
All cache entries that haven't been accessed during that interval are
removed from memory.
