Thread-topic:	blktap and NFS relationship

Hello guys, one question hopefully easy for some of you.

Look this example:

Server1 (using tap2) with:

tap:tapdisk:aio:/nfsserver/disk

Where "nfsserver" is mounted in DOM0 pointing to my test system (Server-NFS1) 
and "disk" is a image with Linux CentOS.

Everything works fine (Linux boots, I can use it, etc), but I CAN access THE 
SAME IMAGE using another server (say Server2). I can boot the image and use it. 

Shouldn´t blktap2 open the image in exclusive mode ? How can I force this 
behavior ?

Thanks in advance.

Antonio
