On Linux the sysrq only does anything if kexec is in use and a crash image has been provided (crash_kexec). Perhaps you should do the same and make this part of the Xen portion of your kexec patches? Also please use D (dump?) instead of p. p is already used by the performance counters. I'm a bit concerned that we might eventually run out of keys... Is this really useful? christian _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
