Hi all,

i just installed ovm on my lab pc for learning purposes.

my lab pc is a Gigabyte X79-UD5 motherboard with sandy bridge processor and 32 gb ram.

the installation went ok but when i wanted to discover it with OVM manager i received :

"Caused by: OVMAPI_4004E Server Failed Command: discover_server , Status: org.apache.xmlrpc.XmlRpcException: exceptions.RuntimeError:Command: ['xm', 'info'] failed (1): stderr: Error: Unable to connect to xend: No such file or directory. Is xend running?

i had a look on the ovm server and noticed following in /var/log/xen

PciDeviceParseError: Broken capability chain: 0000:0c:00.0
