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!
Alfred
