[Xen-devel] OpenSolaris zombie domains

[Robert Nelson <robertn@xxxxxxxxxxxxxxx>]

I'm running xen 3.1 with Fedora 8 as dom0.  When I shut down an OpenSolaris domU it leaves a zombie domain with state = shutdown:1 and dying:1.  There is one page left allocated.

Here is the result of the "q" command on xen console:

(XEN) General information for domain 3:
(XEN)     refcnt=1 nr_pages=1 xenheap_pages=0 dirty_cpus={}
(XEN)     handle=a30786a8-e959-2c0c-6cbc-d0f4683d4213 vm_assist=00000004
(XEN) Rangesets belonging to domain 3:
(XEN)     Interrupts { }
(XEN)     I/O Memory { }
(XEN)     I/O Ports  { }
(XEN) Memory pages belonging to domain 3:
(XEN)     DomPage 0000000118cfd000: mfn=0000000000118cfd, caf=00000001, taf=0000000080000001
(XEN) VCPU information and callbacks for domain 3:
(XEN)     VCPU0: CPU0 [has=F] flags=0 upcall_pend = 01, upcall_mask = 00 dirty_cpus={} cpu_affinity={0-31}
(XEN)     100 Hz periodic timer (period 10 ms)
(XEN)     Notifying guest (virq 1, port 3, stat -1/0/-1)

>From my limited understanding of xen internals it appears that this is a level 4 page table.  I believe this is a xen bug since it also happens if I destroy the domain rather than shutting down gracefully.
