Hi all,
I finally found where the problem is with the help of a friend. :-)
About this freeze issue, that is mainly because the domU OS cannot get enough
memory as it wants, which is because dom0 gets too much memory (almost all)
from the computer.
solutions:
1. "xm mem-set 0 XXX" to set a suitable memory for dom0, and be sure that is
still enough memory left for domU, which could be checked by "xm info"
2. if you don't wanna use "xm mem-set" everytime you boot up a domU, go to
change the /boot/grub/menu.lst, adding "dom0_mem=XXX" behind the "kernel"
line. Note that here the memory is measured by KB.
This should clear the freeze problem, at least in my case.
Hope this helps :-)
Besides, I still cannot get the network work properly. I cannot ping from dom0
to domU or vice versa. And vif1.0 does not get a IPV4 address when using
ifconfig to check it :-(
Any ideas?
