[Xen-devel] Xen 4.0.1-rc4 and stable 2.6.32.x pvops won''t start xend
When I try to start xend I get the following error messages:
ERROR Internal error: Could not obtain handle on privileged command interface (2
= No such file or directory)
Traceback (most recent call last):
File "/usr/sbin/xend", line 36, in <module>

xen.lowlevel.xc.Error: (1, ''Internal error'', ''Could
not obtain handle on privileged command interface (2 = No such file or
directory)'')
----------------------
I saw some posts to the xen-devel archive from the late June timeframe that
discuss a similar error message but when I went to look at the xc_private.c
source file it doesn''t look anything like the file mentioned in the
emails.
http://lists.xensource.com/archives/html/xen-devel/2010-06/msg01519.html
Anyone have any idea what''s going on? The 2.6.31.13 pvops kernel works
fine.
Thanks,
- Greg

I''ve been on vacation, so I haven''t followed very closely, so I can''t point you to the correct answer :) First check the "Xend (and/or xenstored) does not start when using pv_ops dom0 kernel?" section from http://wiki.xensource.com/xenwiki/XenParavirtOps Does that help? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Beats me why... When I run menuconfig in the 2.6.31 kernel I see the option for XEN_GNTDEV but not in the 2.6.32 kernel. Copying the config from 2.6.31 to 2.6.32 doesn''t help because the driver module is missing from the tree and just won''t show up. I''ll go search the archives some more and see if I can find any answers. Thanks for the pointers. - Greg _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

That branch doesn''t include the gntdev.c device. When I switched back to the xen/stable-2.6.32.x branch it was back again. My confusion I guess, I was under the impression Jeremy''s sr-iov branch was based on the stable-2.6.32.x branch that I had originally posted my patches against. Evidently they''re not. I''m going to chalk it up to code management and branching confusion... - Greg _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
