I've been trying to get Xen working on a quad socket Barcelona system but I
it hangs just after the Xen hypervisor prints "Brought up 16 CPUs"
- The system will run standard Redhat Linux
- Xen will run if I only power up 2 of the 4 sockets (8 of the 16
cores.)
I'm still using Xen 3.0.4 but did try Xen 3.1.0 with out any luck.
If anyone can answer the following I'd be greatfull.
Has anyone been able to successfully bring up Xen on a quad socket AMD
Barcelona system?
it could be BIOS problem
but xen could workaround it.
before bother your BIOS guys
at this time, you could try:
1. build latest linux kernel with kexec support.
2. use kexec to load xen etc.
#!/bin/bash
P_XKI=
KERNEL_VER=2.6.18-49.el5
XEN="$P_XKI"xen.gz-"$KERNEL_VER"
VMLINUZ="$P_XKI"vmlinuz-"$KERNEL_VER"xen
INITRD="$P_XKI"initrd-"$KERNEL_VER"xen.img
./kexec -l "$XEN" --command-line="com1=9600,8n1 cdb=com1"
--module=""$VMLINUZ" ro root=LABEL=/ console=ttyS0,9600,8n1"
--module=""$INITRD""
if it works, you need one BIOS update.
it could be the problem like
