I've come across a need to hotplug PCI devices between dom0 and domU using SR-IOV NIC. But I'm experiencing problems when trying to detach VF more than one PV guests.
I can attach VF to DomU successful as follow:
# xl pci-assignable-list
It seems that everything is working fine and it can work well in DomU. But when I detach VF it report errors as follow:
# xl pci-detach 2 05:10.2
Each guest config is the same like this:
name = "ubuntu-pv-1"
Follow xl dmesg log:
And libxl-driver log:
# cat /var/log/libvirt/libxl/libxl-driver.log
I'm running in Ubuntu 14 using Xen-4.9. I have tested in other machine using the same environment but encountering the same problem.
