[Kimchi-devel] [PATCH v2] [Kimchi] Issue #956: Unable to assign pci passthrough devices through kimchi

[Samuel Henrique De Oliveira Guimaraes]

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 at 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.
