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): kernel-3.1.0-0.rc6.git0.3.fc16.x86_64 How reproducible: Always Steps to Reproduce: 1. Install kernel 2. Boot as HVM under Xen 3. 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.
ok, made this =y. I assume there's no downside to having this always loaded on baremetal ?
Nope. It's just a PCI device driver, so if the device isn't present it does nothing.
