Yosuke,
Thanks for you work.
I have tested your patch works on HVM VT-d side.
I'm relieved to hear that. Thank you.
One suggestion is error handling for user input. e.g. following input error
should be caught by xm:
[root@vt-gang32 ~]# xm pci-attach EdwinHVMDomainVtd2 0:2.0.0 (should be
0:2:0.0)
Error: pci: failed to locate device and parse it's resources - [Errno 2] No such
file or directory: '/sys/bus/pci/devices/0000:00:02.0/driver'
Usage: xm pci-attach <Domain> <domain:bus:slot.func> [virtual slot]
Okay.
The small patch below should fix the issue.
(applied after the previous patch)
Thanks,
Yosuke Iwamatsu
