[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] single kernel for xen0 & xenU
I'm sure someone asked in this list if they can run the same kernel in xen0 and xenU and that the answer was yes, but now I can't find it - did I imagine it? Presumably all I need to do is compile the kernel with frontend and backend drivers and xen will sort the rest out itself right? What disadvantages are there to this approach apart from kernel bloat? Are there any optimisations made in the kernel compile if it is front- or back-end? In the testing phase, especially where the xen api is changing a lot, one of the things I find hard is when I build a new kernel, I also need to recompile iscsi etc. Having to only do this once would make it easier. Which brings up another point, how often these days is xen changing such that a xenU domain won't migrate between domains if one is todays build and another is yesterdays build? Finally, is anyone working on a shared memory filesystem that can be exported by xen0 and read by xenU, and would be available very early on in the boot cycle? I ask because updating modules is one of the hard things to do in xenU on boot when the xenU filesystem isn't readily mountable by xen0. My workaround is to put all the xenU modules in the initrd and copy them out of that on boot into the live filesystem before they are required. Or at least it will be once I get it going. Is anyone interested in a quick howto on that assuming it works well?
