The loglvl=all (and likewise guest_loglvl=all) parameter goes on the Xen
command line in /boot/grub/menu.lst.
If with standard log files you also mean anything Xen prints out over the
serial console, then I'd like you to first see whether SysRq-t generates any
output at the point of the hang (requires that you can see the system console
and that you made sure that SysRq is enabled at all) and second whether sending
'd' over the serial console to Xen provides any output (requires that you
switch input to Xen prior to trying). Any output should be attached here.
Also, I'd want to see your loaded module list.
