Hi: what does the following disk line in domU cfg file tell us??? disk = [ ''file:/home/xen/xenwin2008.img,hda,w'', ''file:/home/xen/windows2008.iso,hdc:cdrom,r'' ]specially hda, w and hdc:cdrom,r??? how can we check for this?

This is rather straight forward. I would suggest you read this. I''ve only been playing around which Xen for three weeks now and this guide helped me a lot. http://www.centos.org/docs/5/html/5.2/Virtualization/index.html The first part provides the domU with an hda device which is an image file on the host (dom0) located at "/home/xen/xenwin2008.img". And this is presented in read+write mode (hence the "w"). The second part provides the domU with an hdc device which is a simulated CD-ROM device in read mode. And the source is an ISO file of a Windows 2008 DVD. - Hans _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

copied the list again. does your bridge exist when you start the DomU? or do you at least have /etc/xen/xend-config.sxp configured to dynamically create bridges? B.
