Dang. Happens _every_ time :(

On the other hand, virsh isn't used as often with transient domains, and any management app (I'm thinking things like VDSM) that already prefers transient domains probably already knows how to properly wipe storage after the fact, without needing syntactic sugar in virsh.
Well, I think that would require remembering that the user wishes to remove storage in (transient) domain's configuration, and when the daemon stops the domain, it would remove the storage. Or virsh would have to wait if the domain disappears and then undefine the storage, but this would have limited usability as it would require virsh to run while the transient domain is being destroyed.

I see your point. This is this definitely the best option to write it, but I somehow overlooked the curly braces while reading your v3 review :/
ACK with nits in virsh.pod fixed; no need to send a v5.
Thanks, fixed and pushed. Peter -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
