Re: changeset:6989 vm sticking around in shutdown state

We previously discussed adding something like -zombie-X to the name,
where X is the old numeric domid.  That would make it evident that the
domain was hanging around after death.

Yea, so, since Xend looks things up mostly by name, we need to create
the new domain with the real name, and mangle the name of the zombie
so that it mostly gets ignored.

Well, it would keep track of stuck instances, true.  I don't think we
want to keep track of anything that we don't have to.  That's what the
logs are for :)

TK> Name           Id  Mem(MB)  CPU VCPU(s)  State  Time(s)
TK> Domain-0       0      182    -      2   r----    970.7
TK> debian	   3      128    -      2   -b---    502.4
TK> debian.1	   3.1      0    -      2   ---s-     91.1

I think it would/should look like this:
 
Name              Id  Mem(MB)  CPU VCPU(s)  State  Time(s)
Domain-0           0      182    -      2   r----    970.7
debian-zombie-3	   3        0    -      2   ---s-    502.4
debian  	   4      128    -      2   -b---     91.1
