Re: [Xen-devel] [Xen-users] PCI passthrough problems after legacy update of xen 4.1

Ok, I changed so that the corresponding first lines of code looks like this:
   
        if dev.irq: 
            rc = xc.physdev_map_pirq(domid = fe_domid,
                                   index = dev.irq,
                                   pirq  = dev.irq)

(only the first line changed)
Then, after restarting xend, I get a different failure on line 346, which is the last line of the above: "VmError: (17, 'File exists')". Full xend.log attached below.

I can also do tests with the one device which I still manage to pass through (a gpu), if I get specific suggestions on what to look for.

No, not the entire line, just the is_hvm part needs to be dropped.
