Aline,
Actually it'sa backend issue. Today we are raise exceptions but we need to call the task callback for failure instead.
For example, if you do this in your _attach_pci_device() -> vmhostdevs.py:
try: self._validate_pci_passthrough_env() except: cb('Failed', False)
you should see the error.
However, there's a number of issues that can happen in this process and we need a way to send those error to the front-end in order to be able able to display each of them accordingly.
Why do not _validate_pci_passthrough_env() receives cb as parameter and automatically updates the Task status?
I meant that we need to send the translated error message for any error to the frontend. I'll send a patch for that. @Samuel, can you confirm if your code displays the message from the backend in case of failure? Thank you

I've added some console.log('') messages between the getOngoingAttachingDevices function to make sure that it is running and it does runs after the "/plugins/kimchi/vms/*guest*/hostdevs/" request is completed but it is too late to filter for failed devices. I can remove the filter for tasks that are running and always show the latest failure message but I don't think this should be the proper way to tackle this issue.

I think there's a timeout issue when attaching a PCI device. The same doesn't happen when you try to detach it. The first time I try to attach the device, the browser network console shows that the 'kimchi/vms/*vm*/hostdevs' request is not finished, so for this I'll have to show the "loading" backdrop before the "process" callback starts. The problem is that by the time it runs the function getOngoingAttachingDevices() it doesn't show any result because the task already failed.

Almost there! =)
I noticed the following:
1. Tried to attach a device 2. Task was created but it failed
[alinefm@alinefm-TP440 wok]$ curl -H "Content-Type: application/json" -H "Accept: application/json" -k https://localhost:8001/plugins/kimchi/tasks/2 { "status":"failed", "message":"KCHVMHDEV0003E: No IOMMU groups found. Host PCI pass through needs IOMMU group to function correctly. Please enable Intel VT-d or AMD IOMMU in your BIOS, then verify the Kernel is compiled with IOMMU support. For Intel CPU, add 'intel_iommu=on' to GRUB_CMDLINE_LINUX parameter in /etc/default/grub file. For AMD CPU, add 'iommu=pt iommu=1'.", "id":"2", "target_uri":"/plugins/kimchi/vms/opensuse42.1/hostdevs/" }[
3. I could see a request on /tasks?target_uri=status=running&target_uri=/plugins/kimchi/vms/*name*/hostdevs
The problem is the task status is failed. So it is running nothing and no error is shown.

This commit fixes an issue with PCI passthrough devices through Kimchi. It also addresses an enhancement to display success messages when some actions doesn't require the Save button and there's no UI feedback to the user (Issue #975).
v2 - Added error callbacks for kimchi.addVMPCIDevice() and kimchi.removeVMPCIDevice() to display error messages before if starts to track ongoing tasks.
