Description of problem:
Disable the 'autostart' for a running guest, it seems take effect when checking dominfo. But after restart libvirtd service, the guest is stilling running as 'autostart' is enabled.

Version-Release number of selected component (if applicable):
- kernel-2.6.32-24.el6.i686
- libvirt-0.8.1-1.el6.i686

How reproducible:
Always

Steps to Reproduce:
1. # cat vm1.xml
<domain type='lxc'>
	<name>vm1</name>
	<memory>500000</memory>
	<os>
		<type>exe</type>
		<init>/bin/sh</init>
	</os>
	<vcpu>1</vcpu>
	<clock offset='utc'/>
	<on_poweroff>destroy</on_poweroff>
	<on_reboot>restart</on_reboot>
	<on_crash>destroy</on_crash>
	<devices>
		<emulator>/usr/libexec/libvirt_lxc</emulator>
		<interface type='network'>
			<source network='default'/>
		</interface>
		<console type='pty' />
	</devices>
</domain>

7. # virsh list --all

[root@dhcp-66-70-184 Downloads]# virsh dominfo vm1

CPU time:       0.0s
Max memory:     500000 kB
Used memory:    320 kB
Autostart:      disable

  
Actual results:
After restart libvirtd service, the guest is stilling running. (The same behavior like when 'autostart' is enabled)

Expected results:
After restart libvirtd service, the guest should be shut off as the 'autostart' is disabled

Additional info:
When the 'autostart' is enabled, after restart libvirtd service, the guest is running status. This is expected result.

This is NOTABUG because 'autostart' doesn't guarantee anything about shutdown of domains. The result is expected as the API definition.

Comment 5 Daniel Veillard 2010-10-11 15:19:11 UTC

As comment #4 rightly pointed out, when libvirtd stops it doesn't stop the
guests so in this scenario the behaviour is just fine,
