[Xen-users] reboot, destroy, shutdown... always get zombie domains

[David Ballester Montolio <dbm0572@xxxxxxxx>]

Hi to all:

I've a machine under Centos 4.3 running xen 3 and in general, runs very well, the problem comes when i try to shutdown/reboot a domain. Even if I run a shutdown or reboot command inside guest domain or make a destroy/shutdown/save fom xm, the xen guest domain gets zombie state.  By now my only way to have only the Dom0 running is ... reboot the whole machine.

The guests domains are a copy of dom0 filesystems, with necesary changes ( network, services to start/stop, hostname... ) and are used to test oracle monoinstances. As I said, runs very well until i need to shutdown or reboot the domains.

I installed xen dom0 and guests using karanbir singh notes

Here comes relevant info about my domain0 :
