It builds and installs without complaint. "/lib/tls" has been moved to "/lib/tls.disabled". My understanding is that in a stand-alone (no vms running) situation the performance difference between a standard kernel and a xen enabled kernel should be roughly the same. Is this correct? 2.6.10-xen0 boots with no errors, but the mouse seems jerky and slow to respond but is functional. Networking is up and functional. The drives are IDE in a raid0 using lvm. The m/b is typical budget x86 with 1GB ram and 1GHz Athlon. It has been in various uses without failure for a couple years. As a test I created a logical volume "Main/test" of 1G rw and formatted it with ext3. The inode creation part took perhaps 1 second but the journal creation took over 1 minute. I was able to have lunch (and do the dishes) in the time it took to format 18G. Reboot into 2.6.9 non-xen and try the same experiment and the entire process takes less than 2 seconds. I looked in /proc/interrupts but nothing there seems awry, i.e. no runaway counts. Does anyone have any idea what may be wrong or where I should look next?
