I have an xen-3.2.1 source under amd64 arch:
# uname -a
Linux xenserver 2.6.18.8-xen #1 SMP Thu Jul 31 23:51:53 CEST 2008 x86_64
GNU/Linux
I would like to compile a 32bit kernel for my domU, so I did the
following:
# cd xen-3.2.1
# make XEN_TARGET_ARCH=x86_32 linux-2.6-xenU-prep
# cd build-linux-2.6.18-xenU_x86_32
# make ARCH=i386 menuconfig
# make ARCH=i386
# make ARCH=i386 install modules_install
# mkinitramfs -o /boot/initrd.img-2.6.18.8-xenU 2.6.18.8-xenU
Then here is my domU.conf:
kernel="/boot/vmlinuz-2.6.18.8-xenU"
ramdisk = "/boot/initrd.img-2.6.18.8-xenU"
memory = 6144
name = "linserver"
cpus = "0-3"
vcpus = 4
vif = [ 'mac=00:40:f6:54:79:0f, bridge=xenbr0','mac=00:16:3e:00:01:01,
bridge=xenbr1' ]
disk = [ 'phy:/dev/system/linserv_root,sda1,w',
'phy:/dev/system/linserv_usr,sda2,w',
'phy:/dev/system/linserv_var,sda3,w',
'phy:/dev/system/linserv_opt,sda4,w',
'phy:/dev/system/linserv_home,sdb1,w',
'phy:/dev/swap/linserv_swap,sdb2,w' ]
dhcp="dhcp"
root = "/dev/sda1 ro"
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
(this domU is working with another 2.6.18 32bit xen kernel)
However when creating the domU in the xm console I see:

[and it hangs here]
What did I wrong?
