Hello:
My problem has been solved ,I have a mistake of pci-stup
first,i haven't install libpci-devel or pciutils-devel,so when i search xend.log in /var/log/xen/ ,I found this:
[2011-03-23 10:30:59 4914] DEBUG (image:508) signalDeviceModel: orig_state is None, retrying
I have found this reason is: the config_passthough is not set,so that when assigning device,The device model express error about pci-ins which cannot be recognized by HVM . so it say"Error: Timed out waiting for device model action"
The right way is :
reset Domain0 config by updating this "
CONFIG_XEN_PCI_PASSTHROUGH=y
CONFIG_XEN_PCIDEV_BACKEND_PASS=y
"
and recompile。then the problem can be solved.

My Dear:
I have a VTD problem on Xen4.0.1.of course,I hide a PCI device,which is audio device:00:1b.0.
my grub config is this:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda2
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-194.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.18-194.el5.img
title Xen Dom0, kernel 2.6.32.12
root (hd0,0)
kernel /xen-4.0.1.gz iommu=1
module /vmlinuz-2.6.32.12 root=LABEL=/ ro xen-pciback.hide=(00:1b.0)
module /initrd-2.6.32.12.img
and I reboot to xen4.0.1 and update the HVM config by adding
"pci = [ '00:1b.0' ]"
however,when i excute
#xend start
#xm create winxp
I found that it gave the following information:
[root@localhost xen]# xm create winxp
Using config file "./winxp".
Error: Timed out waiting for device model action
[root@localhost xen]#
What this problem is?
