[libvirt] [RFC] Question regarding the validity of QEMU capabilities

2017-10-20 Thread Marc Hartmayer
Hi all, the actual capabilities of QEMU are depending on the host. This includes dependencies like which kernel modules are loaded or which kernel parameters are used (e.g. kvm.nested). Therefore, after a restart we cannot be sure that the QEMU capabilities remain the same. How can we solve this
