I was waiting for opensuse 11.2 to migrate the guests, in order to have the support for xenpm ( cpufreq and cpuidle ), that comes with the new kernel and the new version of xen.
Even if i disable cpufreq and cpuidle at boot in the xen command line, after a few minutes, the system freeze, with the 3 led of the numeric pad blinking!!!
There is nothing in the log, telling me the reason… ( kernel ?? xen ?? ).
To watch kernel crash Xen system has to be setup with serial console.View: XenParavirtOps - Xen Wiki
For instance:-
title Xen dom0-test (2.6.31.5) with serial console
root (hd0,0)
kernel /xen-3.4.gz dom0_mem=1024M loglvl=all guest_loglvl=all com1=9200,8n1 console=com1
module /vmlinuz-2.6.31.5 ro root=/dev/vg00/lv01 console=hvc0 earlyprintk=xen
module /initrd-2.6.31.5.img
root=/dev/…/ for xenified kernel on OpenSuse 11.2 will be a bit different, like for your normal grub entry. Been connected via NULL modem cable to another Linux box Xen Instance will sent bootup messages to /dev/ttyS0 on the second box and provide you login prompt on the first one ( if Dom0 loaded ok). In case of system crash, kernel stack trace may captured in same file :-
cat /dev/ttyS0 | tee log
In meantime i have same keyboard behaviour during crashes xenified kernel on OpenSuse 11.2 RC2(2.6.35-01).
