Hi, all, I just found out that xen assigns the NOOP disk scheduler for linux guest OSes. Dom0 uses cfq scheduler (it is the linux default). Is there a reason for xen to turn off disk request merging in the quest OS by selecting a NOOP scheduler? Is it because the request optimization will be performed in dom0 or VMM ? Thansk in advance, Jia. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
