See the COPYING file in the top-level directory. + +Introduction +------------ +The QEMU qcow2 driver has two caches that can improve the I/O +performance significantly. However, setting the right cache sizes is +not a straightforward operation. + +This document attempts to give an overview of the L2 and refcount +caches, and how to configure them. + +Please refer to the docs/specs/qcow2.txt file for an in-depth +technical description of the qcow2 file format. + + +Clusters +-------- +A qcow2 file is organized in units of constant size called clusters. + +The cluster size is configurable, but it must be a power of two and +its value 512 bytes or higher. QEMU currently defaults to 64 KB +clusters, and it does not support sizes larger than 2MB. + +The 'qemu-img create' command supports specifying the size using the +cluster_size option: + + qemu-img create -f qcow2 -o cluster_size=128K hd.qcow2 4G + + +The L2 tables +------------- +The qcow2 format uses a two-level structure to map the virtual disk as +seen by the guest to the disk image in the host. These structures are +called the L1 and L2 tables. + +There is one single L1 table per disk image. The table is small and is +always kept in memory. + +There can be many L2 tables, depending on how much space has been +allocated in the image. Each table is one cluster in size. In order to +read or write data from the virtual disk, QEMU needs to read its +corresponding L2 table to find out where that data is located. Since +reading the table for each I/O operation can be expensive, QEMU keeps +an L2 cache in memory to speed up disk access. + +The size of the L2 cache can be configured, and setting the right +value can improve the I/O performance significantly. + + +The refcount blocks +------------------- +The qcow2 format also mantains a reference count for each cluster. +Reference counts are used for cluster allocation and internal +snapshots. The data is stored in a two-level structure similar to the +L1/L2 tables described above. + +The second level structures are called refcount blocks, are also one +cluster in size and the number is also variable and dependent on the +amount of allocated space. + +Each block contains a number of refcount entries. Their size (in bits) +is a power of two and must not be higher than 64. It defaults to 16 +bits, but a different value can be set using the refcount_bits option: + + qemu-img create -f qcow2 -o refcount_bits=8 hd.qcow2 4G + +QEMU keeps a refcount cache to speed up I/O much like the +aforementioned L2 cache, and its size can also be configured. + + +Choosing the right cache sizes +------------------------------ +In order to choose the cache sizes we need to know how they relate to +the amount of allocated space. + +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 + +With the default values for cluster_size (64KB) and refcount_bits +(16), that is + + disk_size = l2_cache_size * 8192 + disk_size = refcount_cache_size * 32768 + +So in order to cover n GB of disk space with the default values we +need: + + l2_cache_size = disk_size_GB * 131072 + refcount_cache_size = disk_size_GB * 32768 + +QEMU has a default L2 cache of 1MB (1048576 bytes) and a refcount +cache of 256KB (262144 bytes), so using the formulas we've just seen +we have + + 1048576 / 131072 = 8 GB of virtual disk covered by that cache + 262144 / 32768 = 8 GB + + +How to configure the cache sizes +-------------------------------- +Cache sizes can be configured using the -drive option in the +command-line, or the 'blockdev-add' QMP command. + +There are three options available, and all of them take bytes: + +"l2-cache-size": maximum size of the L2 table cache +"refcount-cache-size": maximum size of the refcount block cache +"cache-size": maximum size of both caches combined + +There are two things that need to be taken into account: + + - Both caches must have a size that is a multiple of the cluster + size. + + - If you only set one of the options above, QEMU will automatically + adjust the others so that the L2 cache is 4 times bigger than the + refcount cache. + +This means that these options are equivalent: + + -drive file=hd.qcow2,l2-cache-size=2097152 + -drive file=hd.qcow2,refcount-cache-size=524288 + -drive file=hd.qcow2,cache-size=2621440 + +The reason for this 1/4 ratio is to ensure that both caches cover the +same amount of disk space. Note however that this is only valid with +the default value of refcount_bits (16). If you are using a different +value you might want to calculate both cache sizes yourself since QEMU +will always use the same 1/4 ratio. + +It's also worth mentioning that there's no strict need for both caches +to cover the same amount of disk space. The refcount cache is used +much less often than the L2 cache, so it's perfectly reasonable to +keep it small. + + +Reducing the memory usage +------------------------- +It is possible to clean unused cache entries in order to reduce the +memory usage during periods of low I/O activity. + +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. + +This example removes all unused cache entries every 15 minutes: + + -drive file=hd.qcow2,cache-clean-interval=900 + +If unset, the default value for this parameter is 0 and it disables +this feature. + +Note that this functionality currently relies on the MADV_DONTNEED +argument for madvise() to actually free the memory, so it is not +useful in systems that don't follow that behavior. diff --git a/qapi/block-core.json b/qapi/block-core.json index 7b2efb8678..bb2189ef3a 100644 --- a/qapi/block-core.json +++ b/qapi/block-core.json @@ -1592,6 +1592,10 @@ # @refcount-cache-size: #optional the maximum size of the refcount block cache # in bytes (since 2.2) # +# @cache-clean-interval: #optional clean unused entries in the L2 and refcount +# caches.
