Hi, I'm new to KVM. I'm doing some test on nested Virtualization with Xen and KVM. I tried to test the Xen hypervisor as L1 over KVM ( Linux 3.9.0) and I found this in "xm dmesg" log ( for the complete log, see the attached file). -------------------------------------------- (XEN) VMX: CPU0 has insufficent VMExit Control (00036fff but requires min 00008200) (XEN) VMX: failed to initialise. -------------------------------------------- I found some bug-traces [1] [2] but the hex value here is different from the previously reported one, so maybe that is a different issue. Will Xen be supported as L1? Many Thanks. Alex [1] https://patchwork.kernel.org/patch/1318301/ [2} https://patchwork.kernel.org/patch/789632/
