Hi,
  I'm trying to install a domU Netbsd on my CentOS 4.2 dom0 system and
am having problems.  Reading the archives says that the INSTALL_XEN3_U
kernel should work but I get the following crash:

[root@pitbull xen]# /usr/sbin/xm console 1
[ Kernel symbol table missing! ]

My netbsd.xen file is as follows:

kernel="/home/njb/xen/netbsd-INSTALL_XEN3_U"
memory=256
name="NetBSD"

vif = [ '' ]

disk = [ 'phy:/dev/VolGroup00/NetBSD,wd0d,w' ]
disk = [ 'phy:/dev/hda,cd0a,r' ]

root="/dev/wd0d"

Has anyone else seen this?
