I am running Xen 4.0.1 with a 2.6.18-194.32.1.el5xen CentOS Dom0. I built and installed the Xen binaries from source. The systems boot successfully however I am having issues bring up DomUs. Here is config:

 

name = ‘xyz'

memory = 256

vcpus = 1

pae = 1

vnc = 1

vncunused = 1

disk = [ 'phy:/dev/vg1/xyz,hda,w' ]

vif = [ 'type=netfront,bridge=xenbr0,mac=04:01:3e:00:04:62' ]

builder = 'hvm'

kernel = '/usr/sbin/hvmloader'

boot = 'c'

device_model = '/usr/sbin/qemu-dm'

 

When I do an xm create on the config, I get the following error:

Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

 

It looks like there is some configuration issue with the backend devices and the hotplug scripts. If I remove the vif line from the config, the VM’s kernel panics because it cannot find the boot device.

 

Do I need to do anything special to have a 2.6.18-194.32.1.el5xen CentOS Dom0 kernel working with Xen 4.0.1?

 

Thanks,

AP
