[Pkg-xen-devel] Bug#721345: xcp-xapi: xl pci-attach is called by xapi in a PCI passthrough attempt. An error is raised due to the use of xapi and the PCI device cannot be attached to the VM.

Package: xcp-xapi
Version: 1.3.2-15
Severity: normal

I am trying to pass an SRIOV virtual function in a virtual machine but the
attempt fails with the following errors shown in the xcp-xapi.log

When trying for a second time I get the following extra line which shows that
the first try has already bounded the virtual function to xen-pciback module:

What I did to make it work is to change the default toolstack from xapi to xl in
the file /etc/default/xen, then I ran the "xl pci-attach <vm-name>
0000:04:00.1" manually and changed the toolstack back to xapi.
Eventually the pci device shows in the VM.
