[Bug 144631] Re: xen guest hangs after mounting filesystem

[Christian Kujau]

As if this bugreport is not long enough already, I want share my
findings here: my DomU (Debian/sid) would stop booting and not be
reachable via ping/ssh:

[    0.515574] EXT3-fs: mounted filesystem with ordered data mode.
[    0.515597] VFS: Mounted root (ext3 filesystem) readonly on device 202:1.
[    0.515621] Freeing unused kernel memory: 308k freed
[    0.564694] Warning: unable to open an initial console.

I think Stephen was right in
https://bugs.launchpad.net/ubuntu/+source/xen-3.1/+bug/144631/comments/20
when he proposed that this bug has nothing to do with the console at all
- the "Warning:" just happens to be the last visible (error)message.
Booting really seems to stop and I was able to "solve" it by modifying a
completely different parameter: first I had:

  root            = '/dev/xvda1 ro'

which is similar to Todd's config. I changed it to:

  root            = '/dev/xvda1'

And even though the "Warning:" is still there, the system boots just
fine. I have no local Xen console (but that's another bug or PEBKAC) and
I have *no* extra/xencons/console settings in my .cfg now. And even when
I had, the machine would not boot until I changed the root parameter.

HTH,
Christian.
