OOPS in hvc / virtconsole
I'm running a Fedora distro kernel (3.13.7-200.fc20.x86_64) in kvm
with these options:

-append console=hvc0 console=ttyS0

(There are more, but these are the interesting ones, I think.)
Note that virtio_console is modular, which might be a problem.

Problems with booting Debian DomU
I''m running Xen 3.2 on Debian 5.0 (Lenny) and am having trouble booting up a Debian Etch DomU. It hangs at the end when it says "Starting periodic command scheduler: cron."
It''s just completely frozen. At one point I set it sit for a few hours and got back into the console and it said something about "time went backwards" but I used the

reg dom0 console
Hello All,
After a few months of hiatus, we have resumed working on mips port of Xen.
We are at the point of booting dom0 userland (init process and its
children).
The init process gets spawned and in turn forks off processes to run
commands in /etc/rc.d/init.d/rcS. However, the getty process does not seem
to run subsequently and hence the login prompt is not displayed. Dom 0 does
not use the

Xen 4.0 - No console prompt after booting domU but functional SSH
Hello xen-users !
I am coming for help concerning the just released 4.0 version. Install has
worked rather well on my Debian Lenny. I have just had a few bugs for which
I have found the answer looking around on this list.
I have created a Debian Lenny domU which boots up just fine. The only
problem is that I am unable to get a console prompt when using "xm console
nameofdomU". I do see

/dev/hvc0: No such file or directory
Hi Everyone,
In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU,
in /var/log/auth.log, I see:
/dev/hvc0: No such file or directory
listed a lot of times. I''m not experiencing any problems, however it
makes looking through logs for auditing purposes a bit annoying.
Any ideas what this is? I think it has something to do with the

Hello everybody!
My server with Ubuntu Hardy Heron x64 with Xen 3.2 hangs on when booting at
"Starting local boot scripts (/etc/rc.local)".
My /etc/rc.local is default and I can''t find out why it stops there.
It''s possible to SSH to the server and everything works fine. I just can''t

domU only booting with extra = ''xencons=tty1''

guest (installed with debootstrap like this

the VM hangs right after starting crond. This is exactly before the

[XCP] Console with PV kernels?
All:
I''m currently using the older Python-based Xen tools on a cluster of
machines, but we''re looking to transition to XCP as the platform of choice
for our applications. However, I''ve run into one issue that''s sort of a
blocker: paravirtual Linux domUs boot and run, but the console device is
strangely broken. Most of the output reaches the connected user (some

Unable to xm console in a running domU
Hi list,
I am running a virtualized server. Dom0 uses Xen 3.2.1 with Debian
Etch and a custom kernel 2.6.21 created by my webhosting company.
I install my domU using debootstrap for a Debian Etch with
2.6.18-6-xen-amd64 kernel. Everything works well except the fact that
once the VM is started I cannot "xm console" into it. It only works
while it is booting and while it is shutting

xen 2.6.26 on amd64 console troubles
I just installed xen-linux-system-2.6.26-1-xen-amd64 2.6.26-7 on a
freshly installed Debian Lenny AMD64 system, and when I create a
Debian Lenny DomU with xen-tools I cannot attach to a console nor log
in with SSH. When running
# xm create -c test.cfg
the system starts booting, but it seems to "freeze" after the kernel has booted.
Googling a bit, shows that I seem to have the problem

Can I use SGI''s kdb with a dom0 pv-ops kernel?
I asked this a few weeks ago but didn''t get a response, so at the risk of
being a nag, I''ll abbreviate and restate.
I know there are other Xen specific debuggers, but I want to know if there''s
any reason why SGI''s kdb, http://oss.sgi.com/projects/kdb, should not be
included in a dom0 pv-ops kernel?
While the patches apply cleanly and build, the result is that

console lock up
hello,
I am using 2.6.21, lguest-2.6.21-307.patch.gz and an image from
http://uml.nagafix.co.uk/Fedora7/Fedora7-x86-root_fs.bz2
the console hangs, is this expected or caused by the image? I can
still ssh to it or if I boot in single user mode the console is
available but running init3 and it's hung.
also is it possible to get the last gz patch released for 2.6.21?

linux-image-2.6.24-1-xen-686
Hello!
I updated a Xen domU using linux-image-2.6.24-1-xen-686, adapted the Xen
configuration (add ``extra = "console=hvc0"'' and use xvdX devices --
where is all this documented, by the way?) and it boots and I can log in
via SSH, but I don't get a login session anymore on the domU's Xen
console. Is this a known issue?
