Hi, all!
We are once again faced with the null-domains problem.
At this moment we have xen node with 49 null-domains and if I create new
domain and shutdown it I w'll get a new one null-domain.
All blkback and netback kernel process are exists. There is no qemu
process running.
I can't delete any vif or stop disk, which was used by dead domain.
How we can prevent appearance of null-domains?
How we can unlock resources of existing null-domains?
