What were you trying to do that didn't work?

Have an automated test restore VM from file.

Please provide the package NVR for which bug is seen:

libvirt-10.0.0-1.el9.x86_64
qemu-kvm-8.2.0-2.el9.x86_64

How reproducible:

100% with automated test, 0% success so far trying it manually or with bash scripts

Steps to reproduce

1. The test hotplugs a direct interface, reads interface information on host and in guest. Another test apparently executes a hot plug/unplug of vcpus before the following step.
2. virsh save
3. virsh restore

Expected results

The VM is restore

Actual results

The restore fails with error message

error: operation failed: domain is not running

Additional info

1. This does not reproduce when using QEMU 8.1.0-5
2. The libvirt log (attached) contains the following message after the `migrate-income`call:

   2024-01-19 11:41:51.704+0000: 142784: error : qemuProcessReportLogError:1925 : internal error: QEMU unexpectedly closed the monitor (vm='avocado-vt-vm1'): 2024-01-19T11:41:51.703533Z qemu-kvm: Failed to put registers after init: Invalid argument
