There is ongoing work to have Xen 4.11 for Qubes 4.0. But I wouldn't expect installable alpha builds before December, or even January. > In parallel can I rely on you for some level of support if I try and do the > 4.9 update to 4.0 myself ? For 4.0, much easier (in terms of time) would be to backport that single patch and see if that works. It's here, totally untested (not even build tested): https://github.com/marmarek/qubes-vmm-xen/tree/xen-4.8-amd-iommu You can try building this, by adding to your builder.conf: GIT_URL_vmm_xen = https://github.com/marmarek/qubes-vmm-xen BRANCH_vmm_xen = xen-4.8-amd-iommu Then: make get-sources make vmm-xen # or `make qubes` if you didn't build other components before make iso - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
