hi everybody
i have trouble with pci passthrough of a parallel port adapter. I need this for a key dongle.
The Server is a single machine and i want to use them with the all-in-one plugin from ovirt.
I do some tests with:
Fedora 17, CentOS6.3, Oracle Linux 6.3
latest kernel, qemu-kvm and libvirt from repos. No extras or advanced configurations. Only a simple standard Server.
I install "yum groupinstall virtualization" + virt-manager and some other.
I configure iommu, modul blacklist and some other.
Then i starting a Windows Server 2003 and assign the parallel adapter to the running server. I look in the device manager and found the adapter card.
The dongle work finde and the Datev Lizenz Service are online.
.. so far so good
but when i install on the same Server ovirt. With same kernel qemu-kvm and libvirt!
And i attach the adapter card to the windows server 2003 look in the device manager and found the card with a error "device cannot be start (code 10)"
I am now looking for several days after the error and have diverse tried but I can not keep going.
can someone help me?
Thanks & greetings
Andreas
