Test with scratch build:
libvirt-7.0.0-15.el8_rc.51bc9b53a8.x86_64
qemu-kvm-5.2.0-16.module+el8.4.0+10806+b7d97207.x86_64
Test Steps:
# cat test.sh
#!/bin/bash
DOMAIN=lmn
DISK=sda
TDISK="/dev/sdc"
LOG_FILE="/var/log/libvirt/libvirtd.log"
FIND_STR="not assigned to domain"
rm -rf /tmp/$DOMAIN.s*
for i in {1..100}
do
echo "------$i------"
virsh destroy $DOMAIN
virsh create $DOMAIN.xml;
sleep 3;
virsh snapshot-create-as $DOMAIN --disk-only --diskspec $DISK,file=/tmp/$DOMAIN.s$i;
virsh blockcopy $DOMAIN $DISK $TDISK --wait --verbose;
sleep 2;
virsh blockjob $DOMAIN $DISK --pivot;
virsh dumpxml $DOMAIN | grep /disk -B8
virsh domblkthreshold $DOMAIN $DISK 100
virsh domstats $DOMAIN --block --backing
if [ `grep -c "$FIND_STR" $LOG_FILE` -ne '0' ]; then
break
else
continue
fi
done
# sh test.sh
......
------100------
Domain 'lmn' destroyed
Domain 'lmn' created from lmn.xml
Domain snapshot 1621492378 created

Also do the basic test with the libvirt-7.0.0-14.1.module+el8.4.0+11095+d46acebf.x86_64 and the test script in Comment 5: # sh test.sh ...... ------100------ Domain 'lmn' destroyed Domain 'lmn' created from lmn.xml Domain snapshot 1621991597 created Block Copy: [100 %] Now in mirroring phase <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='block' device='disk'> <driver name='qemu' type='qcow2'/> <source dev='/dev/sdc' index='3'/> <backingStore/> <target dev='sda' bus='scsi'/> <alias name='scsi0-0-0-0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> Domain: 'lmn' block.count=1 block.0.name=sda block.0.path=/dev/sdc block.0.backingIndex=3 block.0.rd.reqs=1 block.0.rd.bytes=512 block.0.rd.times=92180 block.0.wr.reqs=0 block.0.wr.bytes=0 block.0.wr.times=0 block.0.fl.reqs=0 block.0.fl.times=0 block.0.allocation=1074135040 block.0.capacity=1073741824 block.0.physical=2147483648 block.0.threshold=100 Both the auto test and the manual test were passed.
