Re: [Xen-users] Target filesystem doesn't have requested /sbin/init.

Thanks
Alexandre,

I check dmesg at initramfs and it looks /dev/xvda1 is correctly applied. This is very werid.

(initramfs) dmesg

[    0.000000] Initializing cgroup subsys cpuset

[    0.000000] Initializing cgroup subsys cpu

[    0.000000] ACPI in unprivileged domain disabled

[    0.000000] released 0 pages of unused memory

Also, there is /sbin/init. So, it is not about the file missing.

(initramfs) ls /root/sbin/init  -l

-rw-------    1 1000     1000         36992 Jan  1  2011 /root/sbin/init

I also highly suspect whether  root = '/dev/xvda1 ro  is correctly applied.

I think the root file system is not mounted as the following command shows this at initramfs.

(initramfs) df

Filesystem           1K-blocks      Used Available Use% Mounted on

df: /proc/mounts: No such file or directory

Is the above right to check the root file system mounted?

Best,

Jaeyong

Agree, very common couse. That's why i suggested Jaeyong to inspect his root FS first. His config file clearly states "root = '/dev/xvda1 ro'".

Although, sounds like a good idea to check "dmesg" output on initrd busybox prompt, to find out with that parameters was the kernel actually called.
