My error.log notes that InnoDB: Not using CPU crc32 instructions, I’ve added innodb-checksum-algorithm = crc32 to my.cnf but didn’t help. Server is running on Debian Wheezy on VirtualBox, can anybody give me an advice why?
Self answer: it’s VirtualBox related ([url]Chapter 9. Advanced Topics) through CPU supports sse4.2 it must be manually enabled for virtual machine.
