+qemu 8.1.1 and 7.2.6 live migration with qcow2 attached to vm using postcopy crashes
+Description of problem:
+Live migrating a vm with a qcow2 disk attached using postcopy will cause vm to crash during migration.
+Steps to reproduce:
+1. Create a generic vm and attach a qcow2 file to the vm.
+<disk type='file' device='disk'>
+      <driver name='qemu' type='qcow2' cache='none'/>
+      <source file='/var/lib/libvirt/images/jlow2.qcow2'/>
+      <target dev='vda' bus='virtio'/>
+      <boot order='1'/>
+</disk>
+
+2. virsh migrate jlow2 --change-protection --persistent --live --verbose --undefinesource --abort-on-error --postcopy --postcopy-after-precopy --timeout 1 --timeout-postcopy qemu+tcp://10.18.64.118/system
+
+vm will start migrating and then pause on the source and be shut down on the target once migration switches to postcopy

+If postcopy is disabled with command below, migration will succeed:

+virsh migrate jlow2 --change-protection --persistent --live --verbose --undefinesource --abort-on-error  qemu+tcp://10.18.64.118/system
