I downloaded centos 4.2 image from xen-get and used its config to create a new domain.

Here is the cfg

kernel = "/boot/vmlinuz-2.6-xen"
memory = 128
name = "centos.4-2"
nics = 1
dhcp = "dhcp"
disk = ['file:/root/xen/centos/centos.4-2.img,sda1,w', 'file:/root/xen/centos/centos.swap,sda2,w']
root = "/dev/sda1 ro"

The kernel is the same kernel which is booting the machine.

Now when i run xm create /etc/xen/centos.402.xen.cfg, i get the following:

Using config file "/etc/xen/centos.4-2.xen.cfg".
Error: Device 2049 (vbd) could not be connected. Backend device not found.

Any help would be really appreciated.

I am trying to install Xen 3.0 on a athlon machine running Centos 4.1 with 1 gb of ram.

I used the rhel install script from xensource, modified it to setup xen on the machine. Now in between the installation, the script ran out with an error of not able to update grub.conf. I made manual entries inside grub.conf and rebooted inside the xen kernel. The entries i made inside grub.conf are as follows:

title Xen (3.0)
   root (hd1,0)
   kernel /boot/xen-3.gz com1=115200,8n1 dom0_mem=262144
   module /boot/vmlinuz-2.6-xen root=LABEL=/ ro maxcpus=1 console=tty1 console=ttyS0,115200n8
   module /boot/initrd-2.6-xen.img

Now after the installation and successful bootup inside xen kernel, i wanted to create a new domain, while looking in the examples i found that there should be 2 kernels, one for dom0 and other for the rest of the guest domains. However the installation script from xensource installed on one kernel. Now can anyone please tell me how should i proceed ? How do i get a kernel for the other guest domains ?
