We are no more able to give a pci device to one VM.=20
Here is the process we used to assign one device to one VM:=20
- Click on the VM, and then on the tab "Host devices"=20
- In the tab, click on "pin to host" and select the host that will give the=
pci device=20
- Click on "add device", in the window appear all the pci devices: choose t=
he 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=20
- Click on ok=20
- boot the VM.=20
The problem is that in the window that appears, there is not a single pci d=
evice listed (there should be many listed).=20
I checked first: the IOMMU setting is set in the kernel.=20
Our environment:=20
We have two HV running CentOs7.=20
Each of them have three fiber channel cards. First card is connected to a d=
isk array, second one to the first tape library and third one to another ta=
pe library.=20
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.=
=20
What happened:=20
Today we add to upgrade one of the HV (HV1). Both VMs ran on this HV1. We u=
pgraded then restarted the HV1.=20
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.=
=20
I started the VM1: it works fine (I didn't change anything on it).=20
