+description = """After hotplugging a CPU and finishing a migration from node 1 to node 2, the instance on node 2 crashes when virtio block devices are used:
+```
+qemu-system-x86_64: get_pci_config_device: Bad config data: i=0x9a read: 2 device: 3 cmask: ff wmask: 0 w1cmask:0
+qemu-system-x86_64: Failed to load PCIDevice:config
+qemu-system-x86_64: Failed to load virtio-blk:virtio
+qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk'
+qemu-system-x86_64: load of migration failed: Invalid argument
+```
+
+I found the problem also exhibits when using `scsi-hd` in combination with `virtio-scsi`, but not when using IDE hard disks or SCSI disks with an LSI controller. VMs with network cards aren't affected either, as are VMs without virtio disks.
+
+
+Interestingly, the latest QEMU version shipped with Ubuntu 20.04 (4.2.1-Debian 1:4.2-3ubuntu6.29) is able to migrate this VM just fine."""

+4. Start a migration by executing the following QMP command (again substituting `<ip:port>` with the IP:port combination of node 2
+   ```
