Hi
I am using xen 3.0.2 on FC5. I followed all the steps given in this link http://lists.xensource.com/archives/html/xen-devel/2005-01/msg00434.html.
I used linux-2.6.16 to build the dom0.I could successfully build it and start dom0.
Now for creating guest domain, I followed all the steps as given in the document.
I created two partitions sda5 and sda6, and created ext3 file system and swap in them respectively.
This is my .config file:
kernel = "/boot/vmlinuz-2.6.16-xenU"
ramdisk = "/boot/initrd-2.6.16-xenU.img"
memory = 256
vif = [ '' ]
disk = [ 'phy:/dev/sda5,hda1,w','phy:/dev/sda6,hda2,w' ]
root = "/dev/hda1 ro"
This is my fstab file:
/dev/hda1 / ext3 defaults 1 1
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/hda2 swap swap defaults 0 0
When I started the guest domain using xm create –c mydomain, I got a kernel panic:
Using config file "/etc/xen/goddomain".
