Dear Users,
Debian Etch 2.6.18.8-xen from xensource.com with Xen 3.3.0 on AMD64:
After i want to start the HVM i get:
VmError: fail to assign device(1:0.0): maybe it has already been
assigned to other domain, or maybe it doesn't exist.

VmError: fail to assign device(1:0.0): maybe it has already been
assigned to other domain, or maybe it doesn't exist.
I want to passthrough a PCI-E graphiccard to a windows 2000 hvm-guest:
01:00.0 is the correct pci-id from lspci output:
After the pci device is hidden, lspci doesnt show it anymore as expected.
Please see details below:
