Hi, when some Hyper-V enlightenments are added to the domain configuration, e.g. <features> ... <hyperv> .. <vpindex state='on'/> </hyperv> ... I'm observing the following: # virsh create /etc/libvirt/qemu/win2k16.xml error: Failed to create domain from /etc/libvirt/qemu/win2k16.xml error: unsupported configuration: host doesn't support hyperv 'vpindex' feature the feature is, of course, supported in KVM/QEMU. I've bisected the problem to the particular commit: commit 63acb7bfd56f117309e4fcaf438639d4d7bc7dcb Author: Jiri Denemark <jdenemar@xxxxxxxxxx> Date: Mon Jun 17 23:38:46 2019 +0200 qemu_process: Prefer generic qemuMonitorGetGuestCPU Any ideas? -- Vitaly -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
