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.
