[Xen-devel] pvops Domain 0 Creased when boot Xen-unstable on Ubuntu10.04
Hi All, I try to install Xen-4.2-unstable with pvops dom0 kernel(2.6.32.28) on Ubuntu10.04. But the kernel panic when I reboot. The message got with the serial debugging is as the following. And the config file of dom0 kernel is also attached. Can anyone give me some advice? And what''s the problem with my installation? Many thanks, Bei Guan __ __ _ _ ____ _ _ _ \ \/ /___ _ __ | || | |___ \ _ _ _ __ ___| |_ __ _| |__ | | ___ \ // _ \ ''_ \ | || |_ __) |__| | | | ''_ \/ __| __/ _` | ''_ \| |/ _ \ / \ __/ | | | |__ _| / __/|__| |_| | | | \__ \ || (_| | |_) | | __/ /_/\_\___|_| |_| |_|(_)_____| \__,_|_| |_|___/\__\__,_|_.__/|_|\___| (XEN) Xen version 4.2-unstable (root@) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) Mon May 16 18:47:25 HKT 2011 (XEN) Latest ChangeSet: Thu May 12 16:42:54 2011 +0100 23339:f9bb0bbea7c2 (XEN) Bootloader: GRUB 1.98-1ubuntu12 (XEN) Command line: dummy=dummy dom0_mem=2048M com1=115200,8n1 console=com1 (XEN) Video information: (XEN) VGA is text mode 80x25, font 8x16 (XEN) VBE/DDC methods: none; EDID transfer time: 0 seconds (XEN) EDID info not retrieved because no DDC retrieval method detected (XEN) Disc information: (XEN) Found 1 MBR signatures (XEN) Found 1 EDD information structures (XEN) Xen-e820 RAM map: (XEN) 0000000000000000 - 000000000009dc00 (usable) (XEN) 000000000009dc00 - 00000000000a0000 (reserved) (XEN) 00000000000d2000 - 00000000000d4000 (reserved) (XEN) 00000000000e0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 00000000bfeb0000 (usable) (XEN) 00000000bfeb0000 - 00000000bfecb000 (ACPI data) (XEN) 00000000bfecb000 - 00000000bfece000 (ACPI NVS) (XEN) 00000000bfece000 - 00000000c0000000 (reserved) (XEN) 00000000e0000000 - 00000000f0000000 (reserved) (XEN) 00000000fec00000 - 00000000fec10000 (reserved) (XEN) 00000000fed1c000 - 00000000fed20000 (reserved) (XEN) 00000000fee00000 - 00000000fee01000 (reserved) (XEN) 00000000ff000000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 0000000134000000 (usable) (XEN) ACPI: RSDP 000F61B0, 0014 (r0 PTLTD ) (XEN) ACPI: RSDT BFEC103B, 0048 (r1 LENOVO TC-2J 37 LTP 0) (XEN) ACPI: FACP BFECAE2B, 0074 (r1 LENOVO TC-2J 37 PTL 1) (XEN) ACPI: DSDT BFEC42E4, 6B47 (r1 LENOVO TC-2J 37 MSFT 100000E) (XEN) ACPI: FACS BFECDFC0, 0040 (XEN) ACPI: TCPA BFECAE9F, 0032 (r2 LENOVO TC-2J 37 PTL 0) (XEN) ACPI: ASF!

Re: [Xen-devel] pvops Domain 0 Creased when boot Xen-unstable on Ubuntu10.04
Hi,
I did the following steps for PVOps dom 0 kernel (2.6.32.28) on Ubuntu10.04
x64. And debug of Dom0 is attached.
git clone
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.gitlinux-2.6-xen
make menuconfig
make bzImage
make modules
make modules_install
cp -a .config /boot/config-2.6.32.28
cp -a System.map /boot/System.map-2.6.32.28
cp -a arch/x86/boot/bzImage /boot/vmlinuz-2.6.32.28
update-initramfs -c -k 2.6.32.28
update-grub
My xen entry in grub.cfg is as the following.
menuentry "Ubuntu_Xen 4.2 (2.6.32.28)" {
recordfail
insmod ext2
set root=''(hd0,9)''
search --no-floppy --fs-uuid --set 59c64afa-47a8-4a5f-a4cf-dbe3be20cc15
multiboot /boot/xen.gz dom0_mem=1024M loglvl=all guest_loglvl=all
sync_console console_to_ring com1=115200,8n1 console=com1 lapic=debug
apic_verbosity=debug apic=debug iommu=off
module /boot/vmlinuz-2.6.32.28 nopat
root=UUID=59c64afa-47a8-4a5f-a4cf-dbe3be20cc15 ro console=tty0
console=ttyS0,115200n8 console=hvc0 earlyprintk=xen nomodeset initcall_debug
debug loglevel=10
module /boot/initrd.img-2.6.32.28
}
In the debug, there is message like this:
Loading, please wait...
mount: mounting none on /dev failed: No such device
So, is there any error in the grub entry? What other log can I provide?
Thanks,
Bei Guan

Not sure why the UUID hasn''t been read, but you could do ''root=/dev/sdaX'' where X is the correct root partition. This would replace the ''UUID=59...''. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Because the /dev/sda9 is the root fs, so I used ''root=/dev/sda9'' to replace the original one. But it also the same error as the following. Detailed is also attached.

Detailed is also attached. > > > Loading, please wait... > mount: mounting none on /dev failed: No such deviceThis is trying to mount something on /dev, presumably a TMPFS or DEVTMPFS or similar, this fails which apparently cascades into not finding the disk. I suggest you have a dig into your initramfs and try and figure out what specifically it is trying to do and what requirements your distro has put on the kernel configuration. You appear to be getting dumped into a debug shell within the initramfs so you can quite easily have a poke around and see what''s going on I think.

For example. You can do "ls /dev" and "cat /proc/modules" and you can probably even try to run a mount command maybe. You can also double-check things like "cat /proc/cmdline", etc. See if you can determine what devices in /dev are actually available, such as your sda, hda, or xvda devices. Hope that helps.

And I need to give the configure file or module?We are really getting into xen-users@ territory here since this is clearly a user level configuration/understanding issue and not a Xen, or even Linux, code problem. You need to make sure that your kernel''s .config includes support for the your root filesystem. If that support is =m then you also need to ensure the module is loaded by the initramfs, perhaps this will happen automatically once your kernel config is correct otherwise you need to consult your distro documentation.
