I have a Linux virtual server experiencing IO issues from MySQL.

Would using the deadline io elevator possibly be preferable to noop in this case?

Probably not, but it depends on your virtualization platform. This is easy to test (change the I/O elevator and apply the same workload), but I'd suspect lower-level issues... E.g. Your storage back-end or something at the hypervisor level.

noop should be the best scheduler in a VM, with deadline usually the most effective on the hosts. But before any advice is given, you need to elaborate on your setup, maybe you've missed something much more fundamental
