Hi!

parsing for the "pci" parameter for pciback is broken and returns "too
many values to unpack" - errormessage
this error occurs since cs 12070

Tried as command line parameter

    xm create <cfg> pci=00:10.1

and as option in config file itself

    pci= [ '00:10.1']


Please see attached xend.log for backtrace captured from a cs 12392

Hi,

I am having the same problem, described in the "[Xen-devel] xen and latency - sending faxes via capi (fritzcard USB in domU)" thread.
