Hi, Group, I am new to xen. I followed the instructions in Xen 3.0 users manual and created a file based disk. After I ran "xm create -c dev-db1.conf" I got a few screens of bootstraping messages followed by system panic. I have no clue what happened. A few things I tried is: 1. completely disable selinux 2. modified the /etc/fstab in the virtual disk 3. tried a few different kernel images 4. tried to disable ramdisk. 5. disable vif Below is the farthest I went. I''d appreciate any help! BTW, I use Fedora 6 and the rpm versions of xen installation. Thanks!
