and libvirtd dies with a segfault.<br>
<br>
The strange thing is--according to this template, there is<br>
nothing to save at all. Why would it go into "epil" state at all?<br></blockquote><div><br></div><div>The epilog state is also used to clean up the host, so even if nothing has to be saved at all the VMs go through this state (e.g. to remove links, log out from iSCSI sessions...).</div>

I am presuming that this condition can also exist in OpenNebula 3.x<br>
versions. Is there any way to prevent it? </blockquote><div><br></div><div>Yes it is there, and we are working in producing a synchronous delete operation that waits for the cancel of the VM. The current suggested **work around** is to introduce ad-hoc waiting times in the epilog scripts to accommodate the cancel operation. This can be easily added to the epilog scripts.</div>

user by doing onevm shutdown/onevm delete can crash my whole set<br>
of VM hosts if he wants to. A similar race condition can<br>
exist with onevm stop / onevm delete.<br></blockquote><div><br></div><div>Apart from doing a synchronous request we are also evaluating moving the DELETE operation to the ADMIN set. So only oneadmin and oneadmin group are granted permissions to delete a VM. Regular users will still have CANCEL to get rid of running VMs... </div>
