[Xen-devel] Latest pvops dom0 kernel and missing /dev/xen/evtchn, xenstored and xend not starting
Hello, I know there has been some discussion about this already, but I just noticed it myself when I upgraded my testbox. So, I have Xen 4.0.0, and the latest xen/stable-2.6.32.x dom0 kernel, ie. 2.6.32.15. On system startup I notice xenstored and xend fail to start. I look around and notice /dev/xen/ is empty. I do "rmmod xen-evtchn" and "modprobe xen-evtchn" and then I have: # ls -la /dev/xen total 0 drwxr-xr-x 2 root root 60 Jun 19 15:22 . drwxr-xr-x 20 root root 4580 Jun 19 15:20 .. crw-rw---- 1 root root 10, 58 Jun 19 15:22 evtchn Based on some earlier emails it has wrong major/minor? Also "modprobe xen-gntdev" gives this: # ls -la /dev/xen total 0 0 crw-rw---- 1 root root 10, 58 Jun 19 15:22 evtchn 0 crw-rw---- 1 root root 10, 57 Jun 19 15:25 gntdev So what''s the actual problem here? I guess something got changed in the kernel, and now xen tools/scripts should create the devnodes with a different major/minor? Is the correct fix to upgrade Xen to 4.0.1-rcX ? I just want to get this correct so I can update the wiki pages.. it seems many people hit this problem. Thanks! -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

> Is the correct fix to upgrade Xen to 4.0.1-rcX ?Via my experience rc2 should be good. Similar question was asked by myself some time ago. It''s on the list. Boris. P.S. Some CS from xen-unstable ( libxc related) was back ported to xen-4-testing.hg. There was also Keir''s feed regarding this issue. --- On Sat, 6/19/10, Pasi Kärkkäinen <pasik@iki.fi> wrote: From: Pasi Kärkkäinen <pasik@iki.fi> Subject: [Xen-devel] Latest pvops dom0 kernel and missing /dev/xen/evtchn, xenstored and xend not starting To: xen-devel@lists.xensource.com Cc: "Jeremy Fitzhardinge" <jeremy@goop.org> Date: Saturday, June 19, 2010, 8:32 AM Hello, I know there has been some discussion about this already, but I just noticed it myself when I upgraded my testbox.

I mean older xen/stable-2.6.32.x kernels DO work with xen-4.0.0, but the latest xen/stable-2.6.32.x does NOT work with xen-4.0.0.

The problem is that (old) libxc has some completely broken code to re-create the device which ends up destroying any correctly created device if it fails to determine what the major/minor is - and with the change in kernel device name, it does fail.
