Hi all since 5.9.0 configure doesnt find the libxl libs/headers... It works With 5.8.0, with 5.9.0 not... not even if I set --with-libxl What can be the problem?

-- ------ Greetz

I use centos 7 (7.7.1908). these pkgs are installed: xen-hypervisor-4.12.2-1.el7.x86_64 xen-devel-4.12.2-1.el7.x86_64 qemu-xen-4.12.1-1.el7.x86_64 xen-runtime-4.12.2-1.el7.x86_64 xen-licenses-4.12.2-1.el7.x86_64 xen-4.12.2-1.el7.x86_64 xen-libs-4.12.2-1.el7.x86_64 xen-ovmf-20180825-1.gitef529e6ab.el7.x86_64

even with --with-libxl it doesnt work...

Thanks for the report. Do you think it will be enough to simply remove the reference?

libxenlight still depends on a blktap in the CentOS package, but it is a different one that don't have a .pc file. It is easier to remove the reference that to try to write a new .pc file :-). There is xen-4.12.2-2 package that should be available in the testing repo in a couple of hours. Thanks, -- Anthony PERARD
