pci passthrough error "unknown command"pci-ins"

[-- Attachment #1.1: Type: text/plain, Size: 8026 bytes --]

Hi All,

Please help me.

I am now installing the XEN on my PC and trying to config the pci pass
through.

My motherboard is intel DQ45CB which is vtd enabled.
I downloaded the latest xen4.0 source from xen.org which is the latest
release.
I downloaded stable-2.6.32-x dom0 kernel source from jeremy's repository.

After compiling the xen and dom0 kernel, I could play it. I could create
hvm. And the VM was runing very well.

But when I configured the pci pass through, it always failed with  the
following error:

root@charles-dq45:/opt/virtualmachines# xm pci-attach 1 0000:02:00.0

Error: Failed to assign device to IOMMU (0000:02:00.0@100
,msitranslate=1,power_mgmt=0)
Usage: xm pci-attach [-o|--options=<opt>] <Domain> <domain:bus:slot.func>
[virtual slot]
Insert a new pass-through pci device.

when I compiled the xen-tools, it's said the pci pass has been enabled...

Have you tried to have your guest file contain the pci entry instead of
doing hot-plug add? Does that work?

Here is an example:

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048
maxvcpus = 4
serial='pty'
vcpus = 2
disk = [ 'file:/mnt/lab/vs08/root_image.iso,hdc:cdrom,r']
boot="dn"
vif = [ 'type=ioemu,model=e1000,mac=00:0F:4B:00:00:68, bridge=switch' ]
vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']
pci = [ '0000:01:00.0' ]

Ugh, that means you don't have CONFIG_PASSTHROUGH set.. but.

You got it there. So is md5sum of the i386-dm/qemu-dm the same as
/usr/<somewhere>/.../xen/qemu-dm? Maybe you haven't installed the
newer version of QEMU?

Thank your very much for your reply and suggestions!

After googling the internet. I found the problem. My previous xen-tools was
not built with pci-utils. After building it with pci-uitls, i didn't install
it into correct place "/usr/local/". My system was still using the old one.
After I reinstall it, everything was working fine!
