I am able to power on vms on newly upgraded host, But not able to migrate VMs from other hosts to new host or newly upgraded hosts to other hosts. This was worked fine before upgraded. i see below logs Unable to read from monitor: Connection reset by peer internal error: qemu unexpectedly closed the monitor: 2022-01-24T17:51:46.598571Z qemu-kvm: get_pci_config_device: Bad config > 2022-01-24T17:51:46.598627Z qemu-kvm: Failed to load PCIDevice:config 2022-01-24T17:51:46.598635Z qemu-kvm: Failed to load pcie-root-port:parent_obj.parent_obj.parent_obj 2022-01-24T17:51:46.598642Z qemu-kvm: error while loading state for instance 0x0 of device '0000:00:02.0/pcie-root-port' 2022-01-24T17:51:46.598830Z qemu-kvm: load of migration failed: Invalid argument Guest agent is not responding: QEMU guest agent is not connected Guest agent is not responding: QEMU guest agent is not connected Guest agent is not responding: QEMU guest agent is not connected OS Version: RHEL - 8.6 - 1.el8 OS Description: CentOS Stream 8 Kernel Version: 4.18.0 - 358.el8.x86_64 KVM Version: 6.1.0 - 5.module_el8.6.0+1040+0ae94936 LIBVIRT Version: libvirt-7.10.0-1.module_el8.6.0+1046+bd8eec5e VDSM Version: vdsm-4.40.100.2-1.el8 SPICE Version: 0.14.3 - 4.el8 GlusterFS Version: [N/A] CEPH Version: librbd1-16.2.7-1.el8s Open vSwitch Version: openvswitch-2.11-1.el8 Nmstate Version: nmstate-1.2.1-0.1.alpha1.el8
