Re: [Xen-devel] Xen compatibility interface numbering

2. Does Xen/dom0/Xend perform version checking on domUs?
Yes.
Out of curiosity, what happens in dom0 if a domU spoofs its interface
version?
3. Can a binary Xen kernel be queried for its compatibility version?
There's a dom0 op that queries the interface version.
Is this accessible to the management tools, i.e. can Xend report the
dom0 interface version to userland?
If I have a domU binary kernel image (vmlinuz), is there any way to
query its interface version (even a search string for strings+grep)?
4. How frequently does the Xen compatibility interface change?
Only when there's a major release number change.
Major = 1.x, 2.x, 3.x, not 2.0.4 to 2.0.5-pre, right? So the Xen
interface is compatible between 2.0.4 and the testing/unstable tree.
