[Xen-users] CentOS pv boot problems

[Ben C <ben@xxxxxxxx>]

Ok, after several weeks of struggling with Xen 3.3.2 / NetBSD dom0 .. 
trying to run linux domu's paravirtualized .. I finally got CentOS to 
install using the images available on the FTP.
Unfortunately.. after installation, I can't seem to get it to boot.

after running xm -c create Ben1CentOSpv I get:

...[snipped]

I don't know what's going wrong here.  I FINALLY just got them 
installing after what seems an eternity.  Now this! arg.. I have a 
feeling this is something simple, though.
Here is my config:


#-kernels from kernels-xen package
# this is what i'm using to get the above error
kernel = '/home/ben/kernels/centos/vmlinuz-2.6.18-164.15.1.el5xen';
ramdisk = '/home/ben/kernels/centos/initrd-2.6.18-164.15.1.el5xen.img';

#-generic kernel
#kernel = '/home/ben/kernels/centos/vmlinuz-2.6.18-164.el5'
#ramdisk = '/home/ben/kernels/centos/initrd-2.6.18-164.el5.img'

#- installation kernels from ftp
#kernel = '/home/ben/kernels/centosx/vmlinuz'
#ramdisk = '/home/ben/kernels/centosx/initrd.img'

name = "centospv"
memory = "512"
# I tried this and xvda1 ... no go either
#root="/dev/xvda"
disk = [ 'file:/home/ben/fileback/server1.img,xvda1,w', ]
#vif = [ 'bridge=xenbr0', ]
#vif = [ 'type=ioemu, bridge=bridge0, ip=PUB.LIC.IP.ADDR' ]
vif = [ 'mac=aa:00:00:50:02:fa, bridge=bridge0' ]
vcpus=1
on_reboot = 'destroy'
on_crash = 'destroy'

-------

With the generic kernel, I get this error:

Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no 
shstrtab\n')
Which amazes me because I see reference after reference that these 
generic kernels are now "xen ready".  Maybe that's for newer versions of 
Xen?  Regardless, I just need these suckers working!  Any help would be 
appreciated.
Thanks, Ben C
