Hi, had a few problems with using xen:


First:
built a xen from source (tgz) and make dist ... then made initrd with mkinitrd and modules=all in the mkinitrd.conf -> initrd.img was 14mb and set it up in the grub with module /initrd....

on boot it loads the initrd like:
Loading ramdisk into ram .... done

but then NO MODULES in the initrd are being loaded by the kernel, though initrd support is in the kernel, and the kernel states kernel panic (because no sata or raid modules are being loaded).



Second:
Built a kernel with sata support and everything and make 2.6-xen-build and 2.6-xen-install --->
Dom0 differs from xen on boot ...
saved a .config from the kernel , make mrproper, make dist, put .config in kernel path, make dist again... -> xen stated failure in kernel package and asked me to run make mrproper...

so is this called stable or what ?


Greetz anyway,
Amin

First of all, if I'm not mistaken mkinitramfs is better than mkinitrd, so try using this one instead. The second error I think it's related to PAE not being enabled in you custom kernel, so switch it on in:

Processor type and features >> MTRR

That's because you have to have PAE enabled in XEN and in you dom0 kernel.

Installation is not a piece of cake, so take it easy and with time you'll sea how good it works.

Regards,
Miguel
