qemu.tests.pci_devices: Get firmware time to initialize

Before "info qtree" returns the correct values, firmware initialization
has to finish. 10s should be enough (in case we won't define 1000
devices)

qemu.tests.pci_devices: Major config update

Original setups were only for developing the test and some of them
were invalid (impossible for real hw and thus unsupported by kernel).
These setups were checked with pci device developer and they should be

2013-04-16 21:35:56: udev: renamed network interface eth0 to eth4

the root cause of this cause is after the nic driver loaded,
the nic name not changed immediately by udev rules, because
the guest is under heavy working pressure.

This patch modify the guest udev net rules before test,
make guest nic always nemed eth0.

virsh_migrate: remove static mac address for "xml" test

We are using static mac address "ff:ff:ff:ff:ff:ff" which is broadcast
address, but libvirt neads unicast address. Instead of using static mac
address we can leave libvirt to generate one and then obtain that mac
address for further checking in the code.

Direct migration is supported only for xen in libvirt and therefore

virsh.migrate: fix the connect uri

The src uri for migration tests should be gotten from the cfg file
instead from the vm object.

Also change the "connect_uri" into the "virsh_migrate_connect_uri"
and instead of "logging.warning()" that the src_uri or dest_uri aren't
updated use "error.TestNAError()" which will skip the test.
