tailf for 'xm dmesg'?

tailf for 'xm dmesg'?

Hi,

I am a fledgeling Xen developer. I use 'xm dmesg | tail' pretty often to
check the console output generated by my code. Instead of using this command
often, I'd like to have something equivalent to a tailf, where the dmesg
output is continuously printed to a console window. Is there any file that
this output is written to?

Thanks,
Daniel.

There's an option to xenconsoled to make it log xen output to a file. Look
at the --log= option.

If you edit /etc/sysconfig/xencommons (xen-unstable)
or /etc/sysconfig/xend (xen-4.0 and earlier) to set XENCONSOLED_TRACE=hv
then the hypervisor console should get logged under /var/log/xen
somewhere.

That would be a nice feature.
