Xen devel - May 2013 - Exception starting xen

One of my servers ran out of space this morning, and after clearing the errant
logfile, xend would no longer start, and a bit of debugging showed that
/var/lib/xend/state/ppci.xml was truncated - most likely as a result of running
out of space. After deleting this file xend recreated it and all is working
again.

I know I''m still using xm on 4.2 which is considered deprecated, but
what are these files for? And is the recreated version sufficient? And if so why
is the previous content important?

Thanks

James

They are state for the host management aspect of the XenAPI
implementation in xend. This support is pretty incomplete and AFAICT
even more deprecated than xend as a whole.

Unless you are using xend''s managed domain functionality / XenAPI then
I
don''t think it is...
