Hi Guys,
I''m working with xen 4.1, dom0 ubuntu kernel 3.2 and domU-PV
ubuntu-precise.
Well... xm console command doesn''t work. I read <
http://wiki.xen.org/wiki/Xen_Common_Problems> and I can''t resolve.
How can I fix this problem?
Thanks

Hi,
Why don''t you xl console instead? Xm is being phased out.
Thanks

Hi all,
I can''t still resolve.
How Ian Campbell said the xl console command didn''t work.
Well... I tried the script /etc/init/hvc0.conf that Lukas suggested and my
guest.cfg was changed to:
name = "ubuntu-pv"
memory = 256
disk = [''phy:/dev/labprog/ubuntu-pv,xvda,w'']
vif = ['' '']
bootloader = "pygrub"
*extra = "console=hvc0"*
But, I can''t run xm console command. Is there other idea?

pygrub should be getting the console=hvc0 from the grub cfg and
hvc0.conf ought to already exist.
If Ubuntu isn''t setting these up by default during install when
running
under Xen then this should be reported as a bug to Ubuntu.
I''m not familiar with current Ubuntu so I don''t know if these
are
expected to be there i.e. I don''t know if this is a
wishlist/new-feature
bug or just a bug in functionality which is expected to Just Work
already.
Ian.
Current (12.04 LTS) Ubuntu, respectively the 3.2.0 linux-virtual Kernel as well
as the grub-legacy-ec2 are
aware of hvc0.
I think the source of these console problems are the configurable different
presets. One could use tty0
as well as tty1, maybe hvc0 or xvc0 or both of them. The domU I''m
currently peeking into spawns tty0
and hvc0 with tty0 connected to the "serial" xl console and hvc0
connected to vfb/vnc setting. But that
can''t be predicted, it''s easy to configure it the opposite
way.
From my point of view, the definition of virtualization namespaces (hvcN, xvcN,
xvdMN) jumped in far to late.
There have been huge clusters build before one was even thinking about hvc0.
Just my 2 cents, and I''m sorry that this won''t help the OP to
solve his issue easily.
Cheers,
Stephan

Hi, if "running console environment" means, you can see the kernel booting and/or services starting, your domU just doesn''t spawn a tty on hvc0. ssh into your domU (or mount the domU root filesystem), navigate to your domU /etc/init/ and cat tty1.conf | sed ''s,tty1,hvc0,g'' > hvc0.conf reboot your domU and you''ll see a login prompt.
