Paravirtualized systems with Xen tools and a kernel that resides in the Host (Dom0) system. HVM (hardware supported virtualization with special processor features) via a software BIOS taken from qemu (only CPU and Memory management are supported by the processors of current generations). As the Network drivers for hvm don't have PXE support, and don't work with any etherboot image I tried(I'm gonna test again in while, it will work one day, but now yet), I have to make a FAI bootflopy/iso. As I understood it, this won't be possible anymore without the fai-kernels package, and that's why I vote against it, currently. Have you filed a (wishlist) bug for this issue? Against what? Xen? I did look upstream on the state of the issue, but people are busy with other things, giving unclear answers. It seems to be on their agenda. Mayxbe it works in the meantime, I have to try again some day. I have added a comment to the bug for the removal of fai-kernels a long time ago, saying that I think they are still needed. Henning

Where is the mistake and what can I do? Until recently we have been using bootfloppies, but with a recent kernel version it was no longer possible to fit a kernel supporting all network chips we have in our fai clients on a floppy. It could be done by disabling acpi but then some boards would freeze when booted with this install kernel. We have about 50 different mainboard types to support with about 35 different network chips (different PCI-ID, not necessarily different driver). We have started to eliminate all network cards not being able to do PXE. You can buy Intel Etherexpress 100 PCI Cards on Ebay for 3 EUR each (e.g. 150065437782). In the long run this is probably your best option, because even if you manage to fit a recent kernel on a floppydisk, at some point this will probably not be possible anymore. Booting over PXE is also much faster.

Okay, I want look around. In older versions I don't know this problem. Thanks. -- Best regards, Michael

It's quite possible that the default kernel is not optimized for floppy usage anymore, there are even plans to throw them out totally. (as I understood with the effect that bootfloppy isn't possible anymore than, that's why I don't like this idea - here's another proff that this is still needed, and xen hvm systems also can neither run real nor etherboot pxe at the moment) Still, you can look in the README of the fai-kernels package, there's a documentation on how to build you own fai-kernels, with only the drivers you need. The NIC's are old and have no features how PXE. maybe etherboot? Henning
