Re: FW: [Xen-devel] Creating domain crashes xend with the latest xenunstable tree

[Cherie Cheung <ccyxen@xxxxxxxxx>]

Hi,

I am new to Xen. I also got problem when creating domain in Xen
3.0(unstable version)

I got the following errors:

Using config file "/etc/xen/vcluster.py".

Namely, the errors are
Unknown config field memmap
Unknown config field device_model
Unknown config field device_config
[xend] INFO (XendRoot:122) EVENT> xend.console.create [0, 9, 9609]
Domain construction error: global name 'log' is not defined

Can anyone help me please?

Thanks.
