Hi,
I''m having problem in reducing the memory-size for Dom0. I got it
running
after compiling the xen-unstable source code on FC4. The domain0 starts fine
and I can start DomU also. Initially, Dom0 starts with default memory
(although I''m not sure what that is). However, if I get the following
when
trying to reduce the memory-size for Dom0 as I needed more memory for the
DomU''s.
#xm list
Name ID Mem(MiB) VCPUs State
Time(s)
Domain-0 0 581 1 r----- 12353.5
# xm mem-max 0 384
Error: domain_setmaxmem() takes no keyword arguments
I tried to set a lower value of memory-size (384MB) by putting that value
inside grub entry, which did not help.
tools/python/xen/lowlevel/xc/xc.c has got the definition of
pyxc_domain_setmaxmem() as
static PyObject *pyxc_domain_setmaxmem(XcObject *self, PyObject *args) [**
note that no keywords in the list of parameters]
although, /usr/lib/python/xen/xend/XendDomain.py is using this function as
try:
return xc.domain_setmaxmem(dominfo.getDomid(),
maxmem_kb = maxmem) [** note that
keywords are being sent as arguments]
Since, the things are not matching, is this a bug or am I missing something.
Please help........
Thanks,
Amitayu

Please help........That''s a bug. Thanks for your report. You can just remove the maxmem_kb here and anywhere else that this problem occurs (I recently tidied up the argument handling, and obviously have broken this call). Please note, however, that xm mem-max is dangerous, and using it to shrink the domain will probably crash it. You want to try xm mem-set, which sets a soft limit instead, and will shrink the domain without crashing it. There is a bug outstanding (#212) to remove the xm mem-set command (or at the very least to reduce its potency). Please don''t use it, and use xm mem-set instead.
