Xen 3.2 - 32bit domU on 64 dom0 hangs at boot

Xen 3.2 - 32bit domU on 64 dom0 hangs at boot

[Sébastien RICCIO]

Hi,

While trying the xen-unstable tree, I have trouble starting 32bits domU
on a 64bit dom0
using the kernel supplied in xen-unstable tree.

It hangs when it is starting /sbin/init.

The same domU boots with a  32-bit 3.1 domU kernel on the 3.2 64bit dom0.

Any clues ?

Re: Xen 3.2 - 32bit domU on 64 dom0 hangs at boot

[Sébastien RICCIO]

Hi again,

Sorry to flood :)

Additionnal the 64bit domU doesn't boot neither and is stuck at the init 
too.
I can only boot the domains using a 3.1 domU kernel (on the 3.2 dom0).

Any ideas ?

Thanks a lot !

Re: Xen 3.2 - 32bit domU on 64 dom0 hangs at boot

[Miguel Filho]

Try this:
extra = "xencons=tty console=tty"

In Xen 3.2 the default terminal is xvc0.

For this new behavior to work you need to adapt your domU.

echo xvc0 >> /etc/securetty

And edit /etc/inittab accordingly.

Miguel
