Hi all, My host is qemu-1.1.1 and x64 kernel 3.5.4. The guest is using aio="native"
I am trying to use unsafe cache mode to boost i/o performance. After googling a while, there are some old web page telling that linux native aio do not use host cache. (http://stackoverflow.com/questions/5664105/buffered-asynchronous-file-i-o-on-linux) is it still valid for recent kernel? do i need to change to aio="threads" to take advantage of unsafe cache mode? Thanks in advance. Regards, ching
