The only way I have found to do it is a fragile two-stage process. Amos, thanks for the recipes. I've been able to get some initramfs functionality working using them, and I was able to netboot it. I assume that you want to build an initramfs necessary and sufficient to run xend and launch a domU, so in the following I describe one technique I want to do two things with the initramfs: 1. Run xend as you suggest 2. Boot a utility image to set some things up for a later boot (flash SLOF, configure HBA/SAN settings). This does not require xend running. I'll post a followup if I get xend working from an initramfs. Thanks again. David Daly Research Staff Member 32-003 IBM T.J.

[XenPPC] Crash with ssh
I got the following error this morning from the console on one of our JS21s. I had a program that was supposed to ssh into the blade and reboot it after shutting down GPFS. I don't think it did any of the gpfs shutdown before crashing. Here is the error message. I saw it because I happened to be on the SOL console ( I wouldn't normally be). This is the first time I'm noticing this. I will post again if I see more errors of this kind. cso85:/ # cpu 0x2: Vector: 700 (Program Check) at [c0017b5a7340] pc: c00f62bc: .clear_inode+0x3c/0x120 lr: c00f62b4: .clear_inode+0x34/0x120 sp: c0017b5a75c0 msr: 90029032 current = 0xc0002facc540 paca= 0xc05ae600 pid = 17947, comm = umount kernel BUG in clear_inode at /root/xen-maria-latest/linux/linux-xen-ppc/fs/inode.c:251! enter ? for help 2:mon 2:mon This is built from Maria's tree on 11-9.

Re: [XenPPC] xend start error
Hollis, Your comment on upgrading kernel with Xen seems to be the key. I tried Maria's tree for linux and xen tree and xend start; xm list doesn't give an error message.

Doesn't look like there's much in the domctl path that returns EINVAL. Did you recently upgrade Xen? If so, make sure you install a newer kernel and tools.

[XenPPC] Xen on JS21 - Dom0 rootfs on SAN
I consistently get an error booting Dom0 from a SAN on JS21. I'm using xen_maple_defconfig + QLA2xxx device driver. With an nfsroot boot argument passed in, the system boots fine. With a root=/dev/nfs changed to root=/dev/sdc1 (a lun on the SAN), it mounts the root filesystem, and then fails with the following message: kjournald starting. Commit interval 5 seconds EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Freeing unused kernel memory: 244k freed /bin/bash: /lib/libdl.so.2: version `' not found (required by /bin/bash) /bin/bash: /lib/libdl.so.2: version `' not found (required by /bin/bash) /bin/bash: /lib/power4/libc.so.6: version `' not found (required by /bin/bash) /bin/bash: /lib/power4/libc.so.6: version `' not found (required by /bin/bash) /bin/bash: /lib/power4/libc.so.6: version `' not found (required by /bin/bash) /bin/bash: /lib/power4/libc.so.6: version `' not found (required by /bin/bash) /bin/bash: /lib/power4/libc.so.6: version `' not found (required by /bin/bash) /bin/bash: /lib/power4/libc.so.6: version `' not found (required by /bin/bash) Kernel panic - not syncing: Attempted to kill init! 0Rebooting in 180 seconds..Connection closed by foreign host. The two root filesystems are basically identical, and I can boot and mount the SAN based filesystem as root for a linux kernel (no Xen). This can be repeated on my test blade cso86 (chassis 4 blade 6). I am using yaboot, and the failing configuration is target cxeny2s. David Daly Research Staff Member 32-003 IBM T.J.
