 no, because the xendomains script provided with xentools42 is
 using xl and not xm, and so doesn't need xend.

 Ah, I mean 'xend' is '/etc/rc.d/xend.sh', it spawns xend and
 xenbackendd.
 I'm not sure what xend and xenbackendd do, but it's sure that
 domUs wont't boot as shown below when xendomains.sh is executed
 before xend.sh (as far as /var/run/rc.log is correct).
 Sorry for forgetting detail information.

 This is tail of bootlog for my NetBSD/amd64 6.1_STABLE DomU.
 Once I destroy this domu and re-create again, it
 starts to boot normally.

 you shouldn't start xend and xenbackendd if you're using xl.
 If you're running xenbackendd with xl I guess devices may be attached
 twice.

 I didn't know Xen works without that 2 daemons, oops.
 Thank you for pointing out about it.

 I revert my patched xendomains.sh, turn off XEND in rc.conf, and
 I can boot DomUs normally.
 Please close this PR.


 Thanks,
