...enerate configure scripts with 4.4 version" This series removes some of the really old deadwood from the tools build and makes some other things which are on their way out configurable at build time with a default depending on how far down the slope I judge them to be. * nuke in tree copy of libaio * nuke obsolete tools: xsview, miniterm, lomount & sv * make xend optional, still on by default (for now!) * disable blktap1 by default (needs qemu patch, just posted) * some cleanup of .*ignore Ian.

LOCAL_LIBAIO is prolly a crappy name, but this patch will enable a tool build to select either the local or the system provided libaio. Note, it only builds the local libaio.a so the linker get the right one automatically, so you''ll want to "make -C tools/libaio clean". -JX --- diff -r 1f...

Hi, I am trying to install xen-3.2.0 , but its failing. The rpms used for installing are 1. xen-3.2.0-0xs.fc8.i386.rpm 2. xen-3.2.0-0xs.fc8.src.rpm 3. xen-debuginfo-3.2.0-0xs.fc8.i386.rpm 4. xen-devel-3.2.0-0xs.fc8.i386.rpm 5. xen-libs-3.2.0-0xs.fc8.i386 when I tried installilng the first rpm rpm -ivh /home/devi/Desktop/xen-3.2.0-0xs.fc8.i386.rpm it gave an failed dependencies

All, I''ve gone ahead and built the latest QEMU as a package. The package is in the usual spot, at http://www.thoughtwave.com/emulators.html This is the 20080113 CVS head, built for x86 and sparc. Simply install the most recent package, add /opt/thoughtwave/qemu/bin to your path, and the wrapper scripts there will automagically run the right binaries for your architecture. Have fun

Are you picking up the libaio in tools/libaio? That is an ancient snapshot used to support older distros which don't ship libaio themselves. It rea...

Hi, I have installed Xen on Linux 2.6.11.10 <http://2.6.11.10> and i am trying to do Asynchronous Direct IO on SAS drives. The application which does the asynchronous direct io on SAS drive is running on Domain 0. Actually the IOPs what i get for a 512Bytes IO size is 67, but if i do the same operation on Linux 2.6.11.10 <http://2.6.11.10> native kernel, i get 267 IOPs.Cananyone
