[Xen-devel] Xen compatibility interface numbering

[Rich Persaud <rich.p@xxxxxxxxxxxxx>]

Questions about compatibility between dom0 and domU kernels.   In the 
ideal situation, all domU kernels would be patched to the same level of 
Xen in dom0.   What happens if they are not?
1.  Can an incompatible domU take down or in any way interfere with dom0?

2.  Does Xen/dom0/Xend perform version checking on domUs?

3.  Can a binary Xen kernel be queried for its compatibility version?

4.  How frequently does the Xen compatibility interface change?

5.  Can I run a 2.4 domU against a 2.6 dom0 and vice-versa, if both are 
patched to the same level of Xen?
Thanks,
Rich
