Re: [Xen-users] Dom0 crashed when rebooting whilst DomU are running
As stated, you can alias shutdown to do exactly what you need, it can be as simple as a series of hard-coded operations to a complex custom shell script that parses your domains and closes each with feedback.
I don't know of a specific xl toolstack solution, but if you are using the xm toolstack you can try this:
Keep in mind that without PV on HVM drivers or paravirtualized DomU's you'll have to use the `destroy` command from Dom0, which is not a graceful shutdown.

Hi,
that is true, I understand that, but at least if the Dom0 is rebooting and will destroy the DomU's, the Dom0 itself should not crash and hang that a Hard-reset is needed to reboot.
Is there not any shutdown control, which can shutdown the DomU's from the Dom0 automatically in case of reboot or shutdown? When I manually shutdown all DomU's before rebooting Dom0, then the Dom0 will reboot and come up again.

A 2010 reference:
You could always try running aliasing the shutdown command to shutdown all running domU's by name, but otherwise forcing them to shutdown as Dom0 does could damage your data.

Hello,
when for example the Dom0 needs to be rebooted manually and several DomU's are running,
the Dom0 will crash during shutdown, that just a Manual Hardware Reset will help to reboot.
Current HVM is: Xen 4.1.3
Current Kernel: 2.6.32-5-xen-amd64
Is there a know issue, or what might could case this issue.
When rebooting the Dom0 without having at least one DomU running, then the reboot is successful.
Can someone help me?
Thanks.
Cheers,
Maik
