Uninstalled xentools41, updated pkgsrc tree:

=> Applying pkgsrc patches for xentools41-4.1.0nb1
**************************************
Ignoring patch file /usr/pkgsrc/sysutils/xentools41/patches/patch-ak:

ERROR: Patching failed due to modified or broken patch file(s):

I double checked: removed the xentools41 directory and then cvs update'd
again.

Out of curiosity, could you elaborate on what's not working with xl+PV?
(is it a NetBSD problem, what is needed to fix it, etc)


Will this condition break automatic startup of PV domains
(xendomains="...") ?



Oh, another thing: I noticed the following:

# /etc/rc.d/xencommons stop
/etc/rc.d/xencommons: WARNING: $xend is not set properly - see rc.conf(5).
$xend is not enabled - see rc.conf(5).
Use the following if you wish to perform the operation:
  /etc/rc.d/xencommons onestop

Is this by design? I'm still getting up to speed with the 4.1
differences, but my impression so far is that xend is not required in
4.1 (unless using xm - which as you explained above is needed, for now)

Is that correct? Say whatever problem affecting xl+PV guests is fixed;
Would one still be required to run xend with 4.1?


Regarding my problem with being unable to start HVM/PV guests, it seems
it may be related to
http://mail-index.netbsd.org/port-xen/2011/04/04/msg006586.html. I have
cc'd Sverre, maybe he has something to add to the discussion.


As usual, thank you for taking the time to read my many questions :)
