Subject: [PATCH v2 00/10] Multifd Migration Compression
Date: Wed, 18 Dec 2019 03:01:09 +0100 [thread overview]
Message-ID: <20191218020119.3776-1-quintela@redhat.com> (raw)
[v2]
- rebase on top of previous arguments posted to the list
- introduces zlib compression
- introduces zstd compression
Please help if you know anything about zstd/zlib compression.
This puts compression on top of multifd. Advantages about current
compression:
- We copy all pages in a single packet and then compress the whole
thing.
- We reuse the compression stream for all the packets sent through the
same channel.
- We can select nocomp/zlib/zstd levels of compression.
Please, review.
Juan Quintela (10):
migration: Increase default number of multifd channels to 16
migration-test: Add migration multifd test
migration-test: introduce functions to handle string parameters
migration: Make multifd_save_setup() get an Error parameter
migration: Make multifd_load_setup() get an Error parameter
migration: Add multifd-compress parameter
migration: Make no compression operations into its own structure
migration: Add zlib compression multifd support
configure: Enable test and libs for zstd
migration: Add zstd compression multifd support
