Re: [Libvir] [PATCH]fix the judgment of the domain state between hypervisor and xend



Hi Daniel,

 Okay, it looks like there was an inversion between 's' which should
be shutoff and 'd' which should be shutoff, can you confirm this ?

Yes, I can confirm. But I tested at xen older(3.03) version which doesn't have life-cycle .

# xm list
Name           ID Mem(MiB) VCPUs State   Time(s)
Domain-0        0     1509     4 r-----   2848.5
guest_dom       2      511     2 ---s--     19.1

The domain state is differnet form REMOTE and LOCAL.

# virsh list
Id Name                 State
----------------------------------
 0 Domain-0             running
 2 guest_dom            shut off
# virsh --connect http://10.131.236.110:8000 list
Id Name                 State
----------------------------------
 0 Domain-0             running
 2 guest_dom            in shutdown

This patch fixes it.

# ./virsh list
Id Name                 State
----------------------------------
 0 Domain-0             running
 2 guest_dom            shut off
# ./virsh --connect http://10.131.236.110:8000 list
Id Name                 State
----------------------------------
 0 Domain-0             running
 2 guest_dom            shut off


But  at latest version(xen 3.0.4), the follwing new problem is occured.
The domains which is the state of "shut off"  vanishes.

# ./virsh list
Id Name                 State
----------------------------------
 0 Domain-0             running
 2 guest_dom            shut off

# ./virsh --connect http://10.131.236.110:8000 list
Id Name                 State
----------------------------------
 0 Domain-0             running

I suspect that this cause is changing of XenD behavior with life-cycle.
If XenD is going to return shut off domain information, this patch is needed I think..
Thanks,
Kazuki Mizushima

According to the xm & virsh man page, I make a patch which fixes
the judgment of the domain state between xenHypervisorDriver and xenDaemonDriver.
