Hi, My system is Gentoo x86, with Xen 4.1.2, the kernel is the latest gentoo kernel. My computer supports VT-x, but not VT-d. My guest is Win7 x86, resides on a LVM partition. In my guest, I was installing stuffs, and on my host I ran "dstat -cd 5" and observed IO-starving. Please look at http://pastie.org/3873523. Actually, I am not sure if it is IO-starving. I am new to Xen, and have know idea how Xen would perform in normal scenarios. -- Regards， David Shen http://about.me/davidshen https://twitter.com/#!/davidshen84 _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
