Hi all,
as we all know, one of the main things that can make the qcow2 format
slow is the need to load entries from the L2 table in order to map a
guest offset (on the virtual disk) to a host offset (on the qcow2
image).
We have an L2 cache to deal with this, and as long as the cache is big
enough then the peformance is comparable to that of a raw image.
For large qcow2 images the amount of RAM we need in order to cache all
L2 tables can be big (128MB per TB of disk image if we're using the
default cluster size of 64KB). In order to solve this problem we have
a setting that allows the user to clean unused cache entries after a
certain interval of time. This works fine most of the time, although
we can still have peaks of RAM usage if there's a lot of I/O going on
in one or more VMs.
In some scenarios, however, there's a different alternative: if the
qcow2 image is stored in a slow backend (eg. HDD), we could save
memory by putting the L2 cache in a faster one (SSD) instead of in
RAM.
I have been making some tests with exactly that scenario and the
results look good: storing the cache in disk gives roughly the same
performance as storing it in memory.
|---------------------+------------+------+------------+--------|
| | Random 4k reads | Sequential 4k reads |
| | Throughput | IOPS | Throughput | IOPS |
|---------------------+------------+------+------------+--------|
| Cache in memory/SSD | 406 KB/s | 99 | 84 MB/s | 21000 |
| Default cache (1MB) | 200 KB/s | 60 | 83 MB/s | 21000 |
| No cache | 200 KB/s | 49 | 56 MB/s | 14000 |
|---------------------+------------+------+------------+--------|
I'm including the patch that I used to get these results. This is the
simplest approach that I could think of.
Opinions, questions?
Thanks,
Berto

In scenarios where we have a large qcow2 file stored in a slow storage
backend, we can save memory by storing its L2 cache in a faster drive
rather than keeping it in RAM.

I suppose you used the fact that the cache is now on disk to increase
the cache size so that it covers the whole image?
If so, are you sure that you aren't just testing that accessing memory
in the kernel page cache is just as fast as accessing memory in qemu's
own cache? It seems this would just bypass the cache size limit given to
qemu by instead leaving things cached in the kernel where the limit
doesn't apply.

Well, from a full design standpoint, it doesn't make a lot of sense to me:
We have a two-level on-disk structure for cluster mapping so as to not
waste memory for unused areas and so that we don't need to keep one
large continuous chunk of metadata. Accessing the disk is slow, so we
also have an in-memory cache which is just a single level fully
associative cache replicating the same data (but just a part of it).
Now you want to replicate all of it and store it on disk. My mind tells
me that is duplicate data: We already have all of the metadata elsewhere
on disk, namely in the qcow2 file, and even better, it is not stored in
a fully associative structure there but directly mapped, making finding
the correct entry much quicker.
Therefore, this is not a good idea. The existing structures already
exist and are just better.
However, the thing is that the existing structures also only exist in
the original qcow2 file and cannot be just placed anywhere else, as
opposed to our cache. In order to solve this, we would need to
(incompatibly) modify the qcow2 format to allow storing data
independently from metadata. I think this would be certainly doable, but
the question is whether it is worth the effort.
I'm not sure, maybe it actually is worth the effort. Your patch is nice
and simple and certainly improves things now. But the question is
whether we can't do better than to look up all cluster mappings in a
fully associative table.
Maybe we can at least make the cache directly mapped if it is supposed
to cover the whole image? That is, we would basically just load all of
the L2 tables into memory and bypass the existing cache.

Right, the wording on the table is not clear, but that's what I did. I
also don't think this makes much sense if the cache is not big enough to
cover the whole image.

Fair question: what I checked is that the PSS/RSS values match the
expected values (i.e, they don't grow as you read from the disk
image). If the kernel is caching those pages so accessing them after
MADV_DONTNEED does not require going to disk again is a possibility that
I haven't ruled out.

This is what the man page says:
Note that, when applied to shared mappings, MADV_DONTNEED might not
lead to immediate freeing of the pages in the range. The kernel is
free to delay freeing the pages until an appropriate moment. The
resident set size (RSS) of the calling process will be immediately
reduced however.
I think it makes sense that this is what is happening in your case. Your
patch uses MADV_DONTNEED after every single access, so even if you're
using an SSD, accessing it should be slower than accessing memory. This
means that at least for sequential I/O where cached tables are reused
all the time, your patch would have to be considerably slower than the
default cache.
Maybe try putting the image on some storage where you definitely notice
whether the kernel accesses it or not. Using a floppy should be fun, but
an NBD device connected to qemu-nbd with enabled throttling or tracing
could do the job as well.

Yes but the use case is that the qcow2 image is stored in a slow disk,
so things will be faster if we avoid having to read it too often.
But the data is there and it needs to be read, so we have three options:
1) Read it everytime we need it. It slows things down.
2) Keep (part of) it in memory. It can use a lot of memory.
3) Keep it in a faster disk.
We're talking about 3) here, and this it not about creating new
structures, but about changing the storage backend of the existing L2
cache (disk rather than RAM).

You mean split the qcow2 file in two: data and metadata? I don't think
it's worth the effort.

I don't see how this addresses the original use case that I described.
But leaving that aside, would that improve anything? I don't think the
cache itself adds any significant overhead here, IIRC even in your
presentation at KVM Forum 2015 qcow2 was comparable to raw as long as
all L2 tables were cached in memory.

The root of the performance problem is the L2 table on-disk format,
which also happens to be used as the in-memory L2 table format. It does
not scale to large disk images.
The simplest tweak is to use larger cluster sizes. 64 KB has been the
default for a long time and it may be time to evaluate performance
effects of increasing it. I suspect this doesn't solve the problem,
instead we need to decouple metadata scalability from the cluster
size...
Is it time for a new on-disk representation? Modern file systems seem
to use extent trees instead of offset tables. That brings a lot of
complication because a good B-tree implementation would require quite a
bit of code changes.
Maybe a more modest change to the on-disk representation could solve
most of the performance problem. In a very sparsely allocated L2 table
something like run-length encoding is more space-efficient than an
offset table. In a very densely allocated L2 table it may be possible
to choose a "base offset" and then use much smaller offset entries
relative to the base. For example:
typedef struct {
uint64_t base_offset;
uint16_t rel_offset[]; /* covers 4 GB with 64 KB cluster size */
} L2TableRelative;
uint64_t offset = l2->base_offset + l2->rel_offset[i] * cluster_size;
A final option is to leave the on-disk representation alone but
convert to an efficient in-memory representation when loading from disk.

I'm arguing that we already have an on-disk L2 structure and that is
called simply the L1-L2 structure in the qcow2 file. The cache only
makes sense because it is in RAM.

That's the thing. I don't know.
I definitely like how simple your approach is, but from a design
standpoint it is not exactly optimal, because O(n) for a cluster lookup
is simply worse than O(1).

It just fixes the issue that the cache is fully associative and then the
only issue I would have with your approach is that we are keeping
duplicate data.

I haven't compared CPU usage, though. That may have gone up quite a bit,
I don't know. For large enough images, it may even become a bottleneck.

I am looking at this problem from a different angle:
Assume a qcow2 image created by a known version of QEMU with the option
preallocation=falloc, it is theoretically possible to do a hacky optimization in
qcow2 I/O path that, instead of looking up in L1/L2, we can calculate file
offset for any given virtual address, by adding the file offset of LBA 0.
If we make this optimization a header extention and add it to the spec, it is no
longer a hack, and it should offer nearly the same performance as raw in all
cases - if we say raw is doing "identical mapping" from LBA to file offset, this
new operation mode of qcow2 file is basically doing a "shift by constant" mapping.

Is this a scenario that matters in practice, though? If you want
performance and you don't need COW functionality, just use raw images to
begin with.

It's actually not O(n) anymore since I rewrote that code last year.
When I changed the algorithm to use LRU for cache eviction I also
optimized the lookup:
1) qcow2_cache_put() simply divides the table offset by the cluster
size and it immediately obtains the index.
2) qcow2_cache_get() hashes the offset to do the lookup. In my tests
doing random I/O and a 2048 entry cache the average number of
comparisons was 2.5 (430 before the rewrite).
The cache was ~13% faster after the rewrite, but the results in terms of
actual disk I/O improvements were negligible, because that's not where
the bottleneck is. We even discussed how the hash function that I was
using was weak, but we decided not to touch it because it was not worth
the effort.

I don't know, I don't have any data to suggest that there's a problem
there, particularly after the rewrite from last year I think the cache
is reasonably fast (as long as the cache is big enough; and if it's not
big enough the problem is going to be in the extra I/O).

The intention is actually to combine the advantages of both: external snapshot
can be supported by an allocation status bitmap generated from scanning the
whole L1/L2 table, or even from loading a new type of qcow2 bitmap specifically
for making that efficient.
I share the same doubt as Stefan regarding the on disk format. Modern file
systems support sparse file quite well, so I wonder what advantages are still
there in using L1/L2 tables instead of a simple bitmap, if the user doesn't use
internal snapshot in the first place?

13% is not really what O(1) vs. O(n) is about, but you are completely
right, For some reason I haven't seen that. OK, so the code is indeed
O(1) in the best case (and probably in the average case, too), so that's
good.

So the remaining question is whether we want a cache for the cache. If
the cache is stored directly on an SSD, any access to it has to go there
and back, and that seems like we may still want to have the option of
having an in-RAM cache on top of it.
If we don't want to split the qcow2 file into separate metadata and data
files, then we could still create a sparse temporary file at runtime
which contains all L2 tables. Reading an L2 table then wouldn't go
through the qcow2 file but through that temporary file and our existing
metadata cache would work on top of it.

That would be indeed possible... but I wouldn't have any without data
showing that it's worth it.

And if you modify a table you have to do it in both places.
The basic idea is the same, anyway. I just started with the assumption
that the L2 cache structures don't add significant overhead and went for
the simplest solution (that's why it's an RFC after all).
But implementation details aside, the main question is whether the best
way to go is to keep the existing metadata and store it in a faster disk
or, as Stefan suggested, think about replacing the current structures
with something else that scales better. I think that's at least worth
exploring.
