[Xen-devel] Booting Failures when using linux-2.6.33.2 as DomU with paravirt-ops support

["zhangxiang" <zhangxiang@xxxxxxxxxx>]

Hello, everyone!

 

   I am trying to boot linux-2.6.33.2 as DomU' kernel in my virtualization platform

(Xen-3.4.2, linux-2.6.18.8 as Dom0, paravirtualization, AMD Opteron 2216,

CentOS 5.3 without virtualization support). But it is always core-dump when

booting. The messages are as follows:

The DomU's configuration file is as follows:

kernel = "/boot/vmlinuz-2.6.33.2"

ramdisk = "/boot/initrd-2.6.33.2.img"

memory = 512

name = "vmtmp"

vcpus = 2

vif = [ '' ]

ip = "10.10.135.182"

netmask = "255.255.0.0"

disk = [ 'file:/sda3/vmdisk2,xvda,w']

root = "/dev/xvda rw"

extra = "4"

extra='xencons=hvc0'

 

 

I do this experiment depend on the link:

http://wiki.xensource.com/xenwiki/XenParavirtOps

 

I download linux-2.6.33.2 from www.kernel.org, and make sure that all the following

config options are selected when compling:

CONFIG_PARAVIRT_GUEST

CONFIG_XEN

CONFIG_HVC_DRIVER and CONFIG_HVC_XEN

CONFIG_XEN_BLKDEV_FRONTEND

CONFIG_XEN_NETDEV_FRONTEND

 

I also use /dev/xvdX instead of /dev/sda1 in both DomU's configurion file and /etc/fstab.

 

So I really do not know why the experiment always fails.

Could somebody help me with this?

Thank you very much for your help!
