Hi everyone,
I tried to restore a saved domain but it failed with:
Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/xen/xend/XendDomain.py", line
263, in domain_restore_fd
    return XendCheckpoint.restore(self, fd)
  File "/usr/lib/python2.4/site-packages/xen/xend/XendCheckpoint.py",
line 150, in restore
    balloon.free(xc.pages_to_kib(nr_pfns))
  File "/usr/lib/python2.4/site-packages/xen/xend/balloon.py", line 166,
in free
    raise VmError(
VmError: I need 192512 KiB, but dom0_min_mem is 200704 and shrinking to
200704 KiB would leave only 119668 KiB free.

For some reason, balloon.py get the wrong value for dom0_min_mem. In
grub.conf I set dom0_mem=131072 and xm list shows it correctly:
# xm list 0
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0      128     1 r-----   4906.2

Did I miss something ?

Thanks,
Tuan
