After checking /var/log/xen/qemu-dm-genocide.log I got the following error: newusaxen:~# tail -f /var/log/xen/qemu-dm-genocide.log domid: 9 -c config qemu network with xen bridge for tap9.0 xenbr0 bridge xenbr0 does not exist! /etc/xen/scripts/qemu-ifup: could not launch network script Could not initialize device 'tap' ^C Some googl'ing suggest that Debian Squeeze doesn't use xenbr0 as bridge anymore, but eth0 instead. So I edit the genocide.cfg file and append the vif entry with "bridge=eth0". So now it starts up, but I can't ping the VPS, nor can it ping anything from within the VPS. The instructions I followed are here: http://wiki.debian.org/Xen And it's a bit unclear as to why there's no xenbr0 bridge device. So now I need to figure out how to either add a xenbr0 bridge (the tutorials I got so far are for Debian Lenny, so I don't know if they'll work, and if it will break anything), or why networking doesn't when using eth0 as a bridge. Has anyone gone down the road yet? What is the correct fix / approach to get HVM guests to have full networking? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
