Description Jeremy Fitzhardinge 2011-09-22 21:11:17 UTC
Description of problem:
When running F16 as an HVM Xen domain, the xen-platform-pci driver needs to be present.  If it isn't, then the kernel will unplug the emulated disk and net devices, but never load the corresponding Xen netfront and blkfront drivers, resulting in a system which has no root filesystem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install kernel
2. Boot as HVM under Xen
Actual results:
Boot fails, because it can't find a root filesystem (or any LVM disks)

Expected results:
Boot on PV drivers

Additional info:
Adding "xen-platform-pci" to the dracut config and rebuilding fixes this for me, but the driver should probably just be built in rather than modular.

Comment 1 Dave Jones 2011-09-22 22:34:10 UTC
ok, made this =y.  I assume there's no downside to having this always loaded on baremetal ?

Comment 2 Jeremy Fitzhardinge 2011-09-22 22:45:51 UTC
Nope.  It's just a PCI device driver, so if the device isn't present it does nothing.
