Windows --> *nix.

VM --> dedicated server

datadir="D:/MySQL/data\" -- D: is SSD?

Were your tables MyISAM on the old machine, but InnoDB on new?

How big was the VM?

innodb_buffer_pool_size=8G --> 70% of available RAM

innodb_thread_concurrency=6 -- Why? Try 0

Generally, the settings look good. I don't see anything that can explain the performance problem you are seeing.

Since you have the slowlog turned on, let's check there. Do one of these:
mysqlslowdump -s t
pt-query-digest
Then, let's discuss the 'worst' queries.
