[Xen-users] Xen and Gentoo - 2 tips

Just wanted to share (and archive) some tips for others.

This is just a quick note on how I got a stable Xen (2.0.5) Gentoo with a fresh 2005.0 dom0 and an old gentoo server migrated to domU.

It was fairly easy (more details to follow -- time permitting), but xend kept taking 100% cpu after about a day. I only ssh'd into domU and did not think that the buffer/binary console on xend was a problem. Turns out it was -- here is what I did to fix it:

1. (I use syslog-ng, but you get the idea) Disable logging to the console. Comment out this line in /etc/syslog-ng/syslog-ng.conf:

#log { source(src); destination(console_all); flags(fallback); };

and restart syslog-ng.  (This should solve your xend "buffer" problems.

2. This will not eliminate binary output on the console, but it eliminates most of the binary (colors, etc) from the startup scripts. Add "--nocolor" to your grub.conf (for dom0 if you want) or in the domU start file in 'extra="--nocolor"'.

Hope this helps,
