Hello, I have a question about disk access. (IDE in my case) When I _don't_ boot the xen dom0 kernel and run hdparm -tT Timing buffered disk reads: 156 MB in 3.03 seconds = 51.44 MB/sec When I boot xen dom0 and run hdparm -tT Timing buffered disk reads: 8 MB in 3.22 seconds = 2.48 MB/sec I'm running this on debian testing and compiling xen3.0.0 When booting dom0 I get those fatal errors of the type "ide_generic module not found" (i've seen those on other instalations). While compiling xen from the source I noticed that ide_generic.o (i think) isn't compiled as a module. I'm a bit stuck. Sould I compile ide as a module for dom0? Or perhaps this isn't even the problem? Should I forget about IDE and go and buy SATA? Thanks Chris. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
