Hello everyone,
I have tried to boot the domU folow the below instrctions:
The domU kernel that I used is from https://github.com/linux-sunxi/linux-sunxi.git and the 'sunxi-devel' branch. I have compiled the ramdisk with the domu kernel to boot the domu.
When I xl console the domU , I tried to mount the /dev/xvda to the /mnt and I met this error:
# mount /dev/xvda /mnt
[ 681.934232] end_request: I/O error, dev xvda, sector 2
[ 681.934401] EXT3-fs (xvda): error: unable to read superblock
[ 681.947103] end_request: I/O error, dev xvda, sector 2
[ 681.947244] EXT2-fs (xvda): error: unable to read superblock
[ 681.967089] end_request: I/O error, dev xvda, sector 2
[ 681.967226] EXT4-fs (xvda): unable to read superblock
mount: mounting /dev/xvda on /mnt failed: Invalid argument
#
Then I tried "# dd if=/dev/zero of=/dev/xvda bs=1 count=1000 seek=10000" to test the read and write of /dev/xvda, it also met error:
[ 632.851166] end_request: I/O error, dev xvda, sector 16
dd: writing '/dev/xvda': Input/output error
1+0 records in
0+0 records out
(2) the domu_all.cfg is here:
root@linaro-alip:~# cat domu_all.cfg
kernel = "/root/zImage"
memory = "64"
name = "dom11"
vcpus = 1
serial="pty"
root="/dev/xvda"
extra = "4 console=hvc0,xencons=tty"
disk = [ 'phy:/dev/loop2,xvda,w' ]
vif=[ 'mac=00:16:3e:56:af:69,bridge=xenbr0,type=netfront', ]
Then I boot the domU follow the instructions:
losetup /dev/loop2 /root/domU/rootfs.img
xl -vvv create domu_all.cfg
Add some information ： I want to use the raring rootfs as the rootfs of domu, and the /dev/xvda as the root device of domu, now I compiled the kernel with ramdisk for debug.
Could you give me some advices ? Thank you very much.
Here is the kernel dump of domU:

Based on the log, I think your loop2 might have problem. If you are
using image from Linaro, you should specify the offset in losetup. Here
is one:
> losetup -o 54525952 /dev/loop2 ./rootfs.img
You can also try to mount /dev/loop2 in Dom0. If it is successful, DomU
should work.

Where does the 4 comes from? Is it the partition number? If so, it
should be in root= not extra.

Or use root=/dev/xvda2 on the guest command line/cfg, which would be
more usual I think.
(I'm not convinced this is the error though, since it seems xvda just
isn't working).
duqi could you post the output of "xenstore-ls -fp" while the guest is
running but not able to access its disk.
What is your rootfs device? (IOW what physical medium contains
rootfs.img)

Yes, that would be a useful sanity check.

Thanks very much for your advices.
I want to know how the "54525952" offset can be computed?
Mr Huang, could you give me some advice?

Hi, here is my config of guest now:
kernel = "/root/zImage"
memory = "64"
name = "dom11"
vcpus = 1
serial="pty"
root="/dev/xvda2"
extra = "console=hvc0,xencons=tty"
disk = [ 'phy:/dev/loop2,xvda,w' ]
vif=[ 'mac=00:16:3e:56:af:69,bridge=xenbr0,type=netfront', ]

I have tested the /dev/loop2 in Dom0.
First, before boot the guest， I tried to test the /dev/2 in Dom0 as below:
(1)root@linaro-alip:~# losetup /dev/loop2 /root/rootfs.img
root@linaro-alip:~# mount /dev/loop2 /mnt
[11315.974201] EXT4-fs (loop2): mounted filesystem with ordered data mode. Opts: (null)
root@linaro-alip:~# cd /mnt
root@linaro-alip:/mnt# ls
SHA256SUMS env.sh install mnt root srv var
bin etc lib networkinfo.sh run sys
boot home lost+found opt sbin tmp
dev init.sh media proc selinux usr
root@linaro-alip:/mnt#
(2)root@linaro-alip:~# dd if=/dev/loop2 of=test bs=1 count=10000
10000+0 records in
10000+0 records out
10000 bytes (10 kB) copied, 0.181345 s, 55.1 kB/s
Second, I tested the /dev/xvda in guest, I found that through I dan not mount /dev/xvda to
the /mnt ,but I can read/write the /dev/xvda and the limit is 4096B, I don't know how to explain it.
the test result is here:
when I tried to write to the /dev/xvda：
# dd if=/dev/zero of=/dev/xvda bs=1 count=1000 seek=3096
1000+0 records in
1000+0 records out
# dd if=/dev/zero of=/dev/xvda bs=1 count=1000 seek=3097
[ 109.879542] end_request: I/O error, dev xvda, sector 8
dd: writing '/dev/xvda': Input/output error
1000+0 records in
999+0 records out
when I tried to read from the /dev/xvda, if the count exceed the 4096 , like 4097 , the guest's kernel crashed :

Then I went back to Dom0 and test the /dev/loop2, it always works. Here is the test:
root@linaro-alip:/# mount /dev/loop2 /mnt

root@linaro-alip:/# cd /mnt

bin etc lib networkinfo.sh run sys
boot home lost+found opt sbin tmp
dev init.sh media proc selinux usr

Many thanks again.

Anyway, it looks like your domU is a 3.15 kernel, what is your dom0
kernel version?
Perhaps you are tripping over the blkif ABI breakage in Linux versions
<= 3.13-rc5 which is described in:
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions#Hypervisor_ABI_Compatibility
?

This number comes from the offset of Linaro rootfs image file x 512.
Here is the output from fdisk. You then calculate 106496 * 512.
Disk rootfs.img: 536 MB, 536870912 bytes
255 heads, 63 sectors/track, 65 cylinders, total 1048576 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
vexpress-a9-nano.img1 * 63 106494 53216 c W95
FAT32 ()
vexpress-a9-nano.img2 106496 1048575 471040 83 Linux
Given that you can mount /dev/loop2 in Dom0, I think you don't need this
offset. Another advice/question I have is if you have ext4-fs support
compiled in your DomU kernel?

kernel version?
Hi, Mr Ian
Thanks very much for your advice.
My dom0 kernel version is 3.13.
Perhaps you are tripping over the blkif ABI breakage in Linux versions
<= 3.13-rc5 which is described in:
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions#Hypervisor_ABI_Compatibility
I have changed the domu's kernel version which is identical by the dom0's. And it works!!
But the rootfs has been stuck in init process. I'm sure the rootfs is normal for the dom0. Could you please give me some advices?
The domU's config is here:
kernel = "/root/zImage"
memory = "64"
name = "guest-3.13"
vcpus = 1
serial="pty"
root="/dev/xvda"
extra = "4 console=hvc0,xencons=tty"
disk = [ 'phy:/dev/loop2,xvda,w' ]
vif=[ 'mac=00:16:3e:56:af:69,bridge=xenbr0,type=netfront', ]
Many thanks again.

Not sure where you got this from but ",xencons=tty" is bogus, I suggest
you drop it.
Do you know what runlevel 4 means to your initsystem? If not then

Hi,
Thanks very much for your help.
I edited the $ROOTFS/etc/fstab and add one text:
/dev/xvda / ext4 defaults,noatime 0 1
The blog I follow is here:http://mer.jolladev.net/wiki.php?id=%E6%9E%84%E5%BB%BAdebian_linux_for_cubieboard2
