I had created a vm without device assignment with VT-d, and it could run
normally.

Did you try to create the guest without device assignment with VT-d?

The the vm hang!!
And I used the option pci=routeirq as kernel parameter, but the output is
the same.
And I use the command xm pci-list-assignable-devices, nothing show.
cat /sys/bus/pci/driver/pciback/slots, I can find the pci device what I
needed.
But if I use cat /sys/bus/pci/driver/pciback/permissive, nothing is showed
out.

主题: RE: [Xen-devel] Linux DomU halted very early after booted
withVT-ddevice
Another mothod is to add "console=ttyS0, 115200, 8n1" to guest's kernel
cmdline in domU's grub and use "xm con $hvm-dom-id" in dom0's terminal at
the same time. Then guest's kernel output should redirect to the dom0's
terminal. And once you see the kernel output, maybe you can paste it here,
and it should help to identify this issue.
