Re: destroydevice

Hi again,
It seems to me that really are a problem here. I've created a new virtual machine, but after shuting down it I can't create it again. The error reported is:

[root@inf16 ssh]# xm create /etc/xen/granit.cfg -c
Using config file "/etc/xen/granit.cfg".
Error: destroyDevice() takes exactly 3 arguments (2 given)

Thanks,
Jordi

Ok, thank you!

How long will take for the next release?

Probably a few days before it goes to updates-testing, so don't
expect it to go to updates for at least a week
On the other hand, I can't ignore that error because I can't create any
virtual machine, so Xen does nothing. On redhat 5 b2 it happens the
same. I've changed my servers to FC6 because of this.

Urm - read my explanation below again....

The 'Error: destroyDevice() takes exactly 3 arguments (2 given)' problem
is *NOT* what is causing your guest to fail. It is merely obscuring the
underlying failure - an updated RPM will remove up the 'destroyDevice'
misleading message, but it won't magically make your guest work again.

The fundamental problem is a configuration issue with your guest's virtual
disk or networking. Once you fix the config problem, the guest will work
just fine, with or without an updated RPM for the 'destroyDevice' issue

Hi,
It seems there's a problem on 2.6.19-1.2895.fc6xen xen kernel and the xm
tool: creating a new VM it aborts showing this error:

[root@inf16 ~]# xm create /etc/xen/rata.cfg
Using config file "/etc/xen/rata.cfg".
Error: destroyDevice() takes exactly 3 arguments (2 given)
[root@inf16 ~]#

Anyone knows what is causing this? On the xen-users list there's some
other messages related to this isue (one mine). Mats Petersson say that
this may be causes by a backport.
Its a bug in one of the other patches we applied to the Xen RPM. I'll fix
it in the next release.

There's something broken on the package? There's any easy workarround?
The error above isn't actually the root cause of your problems. What's
happened is that the hotplug scripts for your domain failed to complete
for some reason. Then when XenD is cleaning up from that failure, we
hit the bug above. So wrt to debugging your actual problems, ignore the
error message above. Instead look for a mis-configuration in either your
virtual network card or virtual disk config params.


Dan.
