bhyve: fix SATA address allocation
As bhyve for a long time didn't have a notion of the explicit SATA
controller and created a controller for each drive, the bhyve driver
in libvirt acted in a similar way and didn't care about the SATA
controllers and assigned PCI addresses to drives directly, as
the generated command will look like this anyway:
2:0,ahci-hd,somedisk.img
This no longer makes sense because:
1. After commit c07d1c1c4f it's not possible to assign
PCI addresses to disks
2. Bhyve now supports multiple disk drives for a controller,
so it's going away from 1:1 controller:disk mapping, so
the controller object starts to make more sense now
So, this patch does the following:
- Assign PCI address to SATA controllers (previously we didn't do this)
- Assign disk addresses instead of PCI addresses for disks. Now, when
building a bhyve command, we take PCI address not from the disk
itself but from its controller
- Assign addresses at XML parsing time using the
assignAddressesCallback. This is done mainly for being able to
verify address allocation via xml2xml tests
- Adjust existing bhyvexml2{xml,argv} tests to chase the new
address allocation
This patch is largely based on work of Fabian Freyer.
