You dump the first gigabyte of the physical memory of a guest VM in KVM by Ctrl+Alt+2 and 'pmemdump 0 1073741824 memdump'

The only log message appearing there after I 'sudo reboot' is

    Oct 23 06:02:18 ubuntu-gnome rsyslogd: [origin software="rsyslogd" swVersion="7.4.4" x-pid="1022" x-info="http://www.rsyslog.com"] exiting on signal 15.

I enabled full SysRq with 'echo 1 > /proc/sys/kernel/sysrq' before attempting sudo reboot. Unfortunately alt-sysrq-t/w showed absolutely nothing.

Alt-SysRq+E produced the following messages on /dev/tty1:

    [ 150.506887] SysRq : Terminate All Tasks
    [ 150.507817] init: rc main process (3232) killed by TERM signal
