I use qemu-2.5.0.
This is a part of my xml:
......
<vcpu placement='static' current="1">64</vcpu>
<cpu>
<topology sockets='4' cores='8' threads='2'/>
<numa>
<cell cpus='0-3' memory='524288'/>
<cell cpus='4-7' memory='524288'/>
</numa>
</cpu>
.....
<hostdev mode='subsystem' type='usb' managed='yes'>
<source missing='yes'>
<address bus='1' device='5'/>
</source>
<address type='usb' bus='0' port='4'/>
</hostdev>
....
and this xml will failed to install win2008 with usb, and qemu reports in
its log: cpage out of range(EHCI) 。
but if the part of xml above: <vcpu placement='static' current="1">64</vcpu>
changes to <vcpu placement='static' cpuset='0-1' current="1">64</vcpu> ,
and other part of xml stay the same.
Then it works, I can install win2008 with usb successfully.
I change my qemu to 2.8.0, and the first xml can work too, but I don't know
the reason, and which part of qemu code fix this bug.
Ask for help
