[XenPPC] Question about netbooting with initrd/initramfs
I've been having some trouble netbooting linux on a JS21 with an initramfs, and wanted to see if there were any known issues, etc. Are there any difficulties in netbooting as an image on a JS21 with an initramfs/initrd? Any secret voodoo? I'm using Maria's branch of the linux-ppc kernel both on bare-metal, and on Xen, and I netboot both. Since I've successfully compiled the Dom0 kernel into Xen, so am just concerned with the step of getting the initramfs into the linux kernel. I've followed the instructions straight from the xensource powerpc wiki for building an initrd. I've also tried compiling using the specify initramfs source config option in the build process. I can successfully boot with an initramfs using yaboot, if I specify an option for it, but I have not successfully booted with an initial image over netboot, or through yaboot with all the bootargs compiled into the kernel. Any help or pointers are appreciated. Thanks 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.
Do you see any errors when you run 'dmesg' in Linux?

[XenPPC] Xen boot error: known issue?
Hi, Wanted to let you know that we are trying some things out under Xen now with our CSO environment. A few times when we've booted the system we've seen a Xen error message to the effect of too many spurious interrupts, this is a known issues, rebooting, let the machine cool down. The full message is below. It says it's a known issue, but I thought I would check.

[XenPPC] Xen hangs
I'm running Xen on a JS21 and am using a straight xen_maple_defconfig for Dom0, both cloned from mercurial on xenbits. When I boot from nfsroot, sometimes Xen hangs. I've included a sample output below. I originally thought it was dependant on boot args passed to Xen and Dom0, but now I notice changing behavior, where sometimes a target will boot, and sometimes it will hang. When it does hang, it is always around the same place in the output. Let me know what further tests you would like, and I will do them tomorrow.

[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.
