Issue

What were you trying to do that didn't work? Start a vm, migrate it to another host or do save&&restore on local host. It report error: [root@dell-per740-78 ~]# virsh save avocado-vt-vm1 ./avocado-vt-vm1.save1 Domain 'avocado-vt-vm1' saved to ./avocado-vt-vm1.save1 [root@dell-per740-78 ~]# virsh restore ./avocado-vt-vm1.save1  error: Failed to restore domain from ./avocado-vt-vm1.save1 error: operation failed: domain is not running Please provide the package NVR for which bug is seen: Host&&guest kernel: kernel-5.14.0-408.el9.x86_64 qemu-kvm-8.2.0-2.el9.x86_64 libvirt-9.10.0-1.el9.x86_64 microcode_ctl-20230808-2.20231009.1.el9_3.noarch How reproducible: 80% Steps to reproduce Start a guest Wait for guest os to boot up(not sure whether this is relevant, but in my practice, I can't reproduce this issue if guest os is not fully boot up) Migrate it to another host, or do save&&restore on local host [root@dell-per740-78 ~]# virsh save avocado-vt-vm1 ./avocado-vt-vm1.save1 Domain 'avocado-vt-vm1' saved to ./avocado-vt-vm1.save1 [root@dell-per740-78 ~]# virsh restore ./avocado-vt-vm1.save1 error: Failed to restore domain from ./avocado-vt-vm1.save1 error: operation failed: domain is not running Check qemu log 2024-01-16T11:13:37.586851Z qemu-kvm: Failed to put registers after init: Invalid argument 2024-01-16 11:13:37.790+0000: shutting down, reason=crashed Expected results Migration can succeed, or save&&restore can succeed Actual results Migration fails, or save&&restore fails.
