Thank for your response, I'm quite new on libvirt...
1) virsh blockjob ... -info gave me an empyt list
2( virsh blockjob ... -abort gave me this error: error: Requested 
operation is not valid: another job on disk 'vda' is still being ended....

..but what ?

I'm looking at the man page of virsh to find an useful option for me...
