Hi i'm coworker of Mr Chapelle,
Thank you for your reply.
so if i understand we need to "downgrade" our ovirt engine which is in version
3.6.6.x to version 3.6.5?
But how can we do that?
You would only need to downgrade the 2 hosts to 3.6.5 VDSM. But
thinking of it, you could instead upgrade to 3.6.7 (rc2) - the bug is
fixed there.

Objet: Re: [ovirt-users] PCI Passthrough problem

We are no more able to give a pci device to one VM.
Here is the process we used to assign one device to one VM:
- Click on the VM, and then on the tab "Host devices"
- In the tab, click on "pin to host" and select the host that will give the pci
device
- Click on "add device", in the window appear all the pci devices: choose the
pci card you wish (ex. pci_0000_83_00_0 pci_0000_83_00_1) and then click on the gray
arrow to assign this device to the VM
- Click on ok
- boot the VM.
The problem is that in the window that appears, there is not a single pci
device listed (there should be many listed).
I checked first: the IOMMU setting is set in the kernel.
Our environment:
We have two HV running CentOs7.
Each of them have three fiber channel cards. First card is connected to a disk
array, second one to the first tape library and third one to another tape
library.
We used to give the second card to a VM1, and the third card to another VM2.
Both VMs ran on one HV or on the other in the past: everything was fine.
What happened:
Today we add to upgrade one of the HV (HV1). Both VMs ran on this HV1. We
upgraded then restarted the HV1.
Then I edited the second VM2 in order to remove card from HV1. Then I tried to add the
card from HV2 to this VM2: the list of "host devices" is empty.
I started the VM1: it works fine (I didn't change anything on it).
Hello!
I'm afraid you have hit the bug [1]. For hosts where you need host
devices, the best solution is most likely not upgrading them to 3.6.6
for now.
