Hi, I want to write a puppet module for xen on Debian. This module will need to manage one line in the file /etc/default/grub, namely the line starting with "GRUB_CMDLINE_XEN=". Currently I want to leave the rest of the file untouched. Which would be the best way to do this? I see two options: a) Do some `sed` magic on the file in a `exec` call. Downside: puppet won''t notice when the line gets manually changed. b) Have some support for sections inside...

...d to set clocksource=pit on dom0. How and where, in Squeeze is this clocksource parameter set? At compile time, or at boot time? And if at boot time, in /etc/default/grub?

Hi! I''m experimenting with Xen 4 on Squeeze. Squeeze uses grub2 by default, and the config format has changed. I can''t for the life of me figure out where to set options for the hypervisor and the Dom0 kernel on bootup. It seems the grub2 stanza for xen is being generated by /etc/grub.d/20_linux_xen and that seems to have some provisions for receiving arguments, but I

Hey folks, I am trying to live migrate a guest from a Xeon machine to core i 7 machine and reverse, and my problem is Xeon machine get restarted randomly. The restarting happens both when I migrate from it or to it. The weird part is it happens sometimes, like 40 percent of time the migration works perfectly fine and sometimes Xeon machine gets restarted, I first thought problem is with the
