[Xen-devel] question about PXE

[Tim Freeman <tfreeman@xxxxxxxxxxx>]

I'm having problems doing a remote install on a RH7.3 cluster node.   I
don't have console access, but the admin sent this as the console server
output.  

(XEN) Limiting direct PCI/PCI transfers.
(XEN) *** LOADING DOMAIN 0 ***
(XEN) Xen-ELF header found: 
'GUEST_OS=linux,GUEST_VER=2.4,XEN_VER=2.0,VIRT_BASE=0xC0000000'
(XEN) PHYSICAL MEMORY ARRANGEMENT:
(XEN)  Kernel image:  02800000->02aed8fc
(XEN)  Initrd image:  00000000->00000000
(XEN)  Dom0 alloc.:   02c00000->0ac00000
(XEN) VIRTUAL MEMORY ARRANGEMENT:
(XEN)  Loaded kernel: c0100000->c043b004
(XEN)  Init. ramdisk: c043c000->c043c000
(XEN)  Phys-Mach map: c043c000->c045c000
(XEN)  Page tables:   c045c000->c045f000
(XEN)  Start info:    c045f000->c0460000
(XEN)  Boot stack:    c0460000->c0461000
(XEN)  TOTAL:         c0000000->c0800000
(XEN)  ENTRY ADDRESS: c0100000
(XEN) *** Serial input -> DOM0 (type 'CTRL-a' three times to switch input to 
Xen).
(XEN) Domain 0 shutdown: rebooting machine!

I've only set up Xen on a local machine before, but I know many people
are using PXE.  Because it says Xen-ELF header found is it right to
assume it can get to the dom0 kernel OK?  (the node needs a symbios scsi
controller which is built in, so I am guessing it is not a SCSI
problem).  Is this a problem with the serial output not being directed
or does it really reboot immediately?  I hope to get actual console
access in the machine room tomorrow, but I wanted to get some advice
beforehand. 

Here is the PXE config:

serial --unit=0 --speed=9600
terminal serial
timeout 0
default 0
title=Xen 2.0 with 2.4.27 dom0
root (hd0,0)
kernel /xen.gz dom0_mem=131072 com1=9600,8n1
module /vmlinuz-2.4.27-xen0 root=/dev/sda2 console=tty0 console=ttyS0
boot


Thanks for any insights!

Tim
