Hi, I want to improve the IO performance of the hvm guest OS (use vhd image files on an iscsi target). I saw the source code of block cache driver in blktap2, but don’t know whether it is helpful and how it works. Who can help me ? thank you very much! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
