Re: [Xen-users] domU kernel.org kernel

[Olivier Hanesse <olivier.hanesse@xxxxxxxxx>]

Hello,

You should try with a 2.6.32 pvops dom0 and with xen 4.
It can't work with xen 3.2 and a 2.6.26 kernel

Regards

I've been trying to get a kernel.org 2.6.32.24 kernel to work as the
domU kernel, but have had nothing but failures. The Dom0 is running a
Debian stable (lenny) 2.6.26-2-xen-686 and 3.2-1 xen. I would appreciate
some pointers as to what I am missing to make this work.

I took the kernel.org source, made a .config with these options:

CONFIG_XEN=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=8
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
CONFIG_NETXEN_NIC=m
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
CONFIG_PARAVIRT_GUEST=y
CONFIG_PARAVIRT=y
# CONFIG_PARAVIRT_SPINLOCKS is not set
CONFIG_PARAVIRT_CLOCK=y
# CONFIG_PARAVIRT_DEBUG is not set

Then I build the kernel with a regular 'make' and 'make
modules_install'.

strip vmlinux -o vmlinux-stripped
gzip vmlinux-stripped -c > vmlinuz

Then I copy the vmlinuz out to the dom0 and setup the xen configuration
for the domU to boot from it, but it fails:
