Xen devel - Aug 2006 - About the behavior on an illegal dom0_mem value

Hi, all,

I would like to ask for comments about what behavior you think
appropriate when they supply dom0_mem parameter with a large value
exceeding the size of physical memory.  The current behavior is that a
system stops with warnings and then it reboots.  Attached is the
console log when the system stopped.


There are at least three options, including the current behavior:

1/ Boot Dom0 with the default dom0_mem value (maybe showing warnings.)
2/ Halt and never reboot.
3/ Halt and reboot (current behavior.)

I understand that the current behavior (halt and reboot) is the
ordinary way of handling errors caused by illegal parameters, but
repeating reboot seems not helpful to me.  So, how about #1 ?

Considering the benefit for system administrators, another option is
booting Dom0 in single user mode so that they get a chance to correct
the illegal value immediately.


Best,
Hiroya INAKOSHI
