Steps to Reproduce:
1.The same pool in the both source and target host:
# virsh pool-list
Name State Autostart
-------------------------------
default active yes
pool0 active yes
# virsh pool-dumpxml pool0
<pool type='dir'>
<name>pool0</name>
<uuid>a66e307a-cd3c-4164-95f5-7809392912cb</uuid>
<capacity unit='bytes'>13886460059648</capacity>
<allocation unit='bytes'>1855581720576</allocation>
<available unit='bytes'>12030878339072</available>
<source>
</source>
<target>
<path>/opt/kvm/pool0</path>
<permissions>
<mode>0775</mode>
<owner>64055</owner>
<group>116</group>
</permissions>
</target>
</pool>
2.Show the image of the guest:
# virsh domblklist ubuntu-minimal-18.04
Target Source
-------------------------------------------------------------
vda /opt/kvm/pool0/ubuntu-minimal-18.04.hd-system.img
3.Do storage migration:
# virsh migrate --live --persistent --copy-storage-all --verbose
ubuntu-minimal-18.04 qemu+ssh://10.10.10.10/system
error: Cannot access storage file
'/opt/kvm/pool0/ubuntu-minimal-18.04.hd-system.img': No such file or directory
Actual results:
As step 3,migration failed.
Expected results:
Migrate successfully with pre-creating the image on target pool.
