Problem with multiple hvc consoles via virtio-console
Hello,
When multiple hvc console ports are initialised and used via the
virtio_console driver, I can interact with only the first console, the
2nd one doesn't respond.
If I call hvc_kick() even if hvc_poll() returns 0, the 2nd console
becomes responsive.
I've checked that hvc_poll() receives data via get_chars() and feeds it
to tty_insert_flip_char().
Any idea what could be going

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

CentOS 7 kernel console under KVM?
Is there a way to get GRUB2 and the kernel to run a "serial" console
under KVM?
I'm running a Fedora 20 desktop, with libvirt-managed VMs. When I run a
CentOS 6 VM, I can set both the boot loader and kernel up to use ttyS0
and get a console compatible with "virsh console".
When I try the same with a CentOS 7 VM, it doesn't work. If I set it to
ttyS0, I just

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

[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

/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

Note that virtio_console is modular, which might be a problem.

xen hvc console
I had a quick try to make it work, but no success thus far. Should it
be enough to apply the patch and then boot with "console=/dev/hvc0"?
Also, why do you comment out the EARLY_PRINTK stuff in Kconfig?

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 4.0 - No console prompt after booting domU but functional SSH

I am coming for help concerning the just released 4.0 version. Install has

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
