There is a line "#XENCONSOLED_TRACE=[none|guest|hv|all]" within /etc/sysconfig/xencommons. Currently, this line ("#XENCONSOLED_TRACE=[none|guest|hv|all]") is commented out, so it seems that it is not activated right now?
again, there is no file or directory at /var/log/xen/console in my file system.
you try to start a DomU look if xenconsoled is running (ps augx | grep
xenconsoled). If xenconsoled is not running perhaps you have the
Actually, I the output of the command line does indicate that the xenconsoled is running:
[root@XenTester su]# ps augx | grep xenconsoled
root 3826 0.0 0.0 90480 348 ? SLl 10:10 0:00 xenconsoled --pid-file=/var/run/xenconsoled.pid
root 5119 0.0 0.0 103284 800 pts/2 S+ 10:53 0:00 grep xenconsoled
So it seems that your issue is not exactly same as mine because the XENCONSOLED TRACE is inactivated under my default settings, do you think so?
arround the problem was (as root):
starting daemon by hand
sure the the xenconsoled is running
ps augx | grep
than trying to start a domU (pv).
that all works fine for me including for a system reboot
inspected the "make install" of (4.1.2) and only found the creation
of /var/log/xen directory but nothing for the creation of
/var/log/xen/console. But the source from xenconsoled
depends on that directory.
think that it is a bug in the "make install"

if it is a pv then look if the directory /var/log/xen/console
exists. If some logging options in /etc/default/xen* are enabled xenconsoled
does not start on boot. Because it could not write to
/var/log/xen/console/hypervisor.log. The make install does not create the
missing directory (4.1.2) .
I run in this problem today.
I hope the
above helps you.
Thanks for your reply.
Interestingly, the file /var/log/xen/console doesn't exist on my machine.
There is no any file or directory called /etc/default/xen*. So how did you
address the similar problem? Could you please be a bit specific? Do I need to
generate these files manually? Or How can I generate these files
automatically? Is this issue caused by these missing

domain is to be called "f13" I would have expected a Fedora mirror to be
listed rather than the CentOS 5 mirror. Is this normal?
Do you know if this command will create a PV or an HVM guest?
If this is an HVM domain then it is possible that it simply doesn't have
a text console which you can connect to with xl console. The "Could not
read tty from store" message is often indicative of this.
It appears you have configured VNC for this domain, have you tried
connecting a vncviewer to port 5901 on the host? e.g. vncviewer
localhost:1 or localhost::5091 (check the vncviewer manpage, I'm not
sure of the syntax). Perhaps virt-* includes a command to do this for
If you want a text console from an HVM guest then you can do the
virt-install equivalent of adding
series = 'pty'
that with virt-install though.
If this is a PV guest then I have no idea what might be wrong.
