Without the GPLPV drivers loaded, an 'xm shutdown' does a 'hard'
shutdown but leaves the domain hanging around. An 'xm create' is
required to clean it up.

Xen is amd64 built from 3.3-testing from about a week ago.
Dom0 is also amd64 and is from Debian (vmlinuz-2.6.18-xen-3.3-1-amd64)
DomU is Windows 2003 x32 Enterprise Edition

After the shutdown, while the domain is still hanging around, 'xm list'

bitvs2:~# xm list
Name                              ID   Mem VCPUs      State   Time(s)
Domain-0                           0  1015     1     r-----    314.7
smtp2                              1   512     1     -b----    226.2
virtdemo                           3   768     1     ---s--    206.0

virtdemo is the domain in question.
