You should be able to see if its present in the kernel by looking at
/proc/misc, but something still needs to create the /dev nodes.  Usually
this is udev, but libxc goes to special lengths to get this wrong, and
will end up deleting the perfectly good nodes unless you update it.

Keir, have the libxc changes been backported to all the release trees?

Kernel 2.6.32.10 does create /dev/xen/evtchn been loaded instead of 2.6.32.15

You should be able to see if its present in the kernel by looking at
/proc/misc, but something still needs to create the /dev nodes.  Usually
this is udev, but libxc goes to special lengths to get this wrong, and
will end up deleting the perfectly good nodes unless you update it.

Keir, have the libxc changes been backported to all the release trees?

Re: [Xen-devel] Re: Failure to start xend with 2.6.32.15 (c2cb3df04eb3ff68d0de102b2acacc9b8616e659) under Xen 4.0

   It''s Ubuntu 10.04 Server. All kernels .10, .12, .13, .14, .15 until
commits on 06/07/2010 worked fine.
  My guess would be:  the issue is in the kernel 2.6.32.15 . 
Ubuntu 10.04 udev setup was OK until 06/07/2010 with all kernels 2.6.32.X (
X>=10)
and is still OK when X=10. Two similar instances on top of Ubuntu 10.04 Server
show up same behavior with 2.6.32.10 - OK , with 2.6.32.15  failure to create 
/dev/xen/evtchn

Boris.

[Xen-devel] Re: Failure to start xend with 2.6.32.15 (c2cb3df04eb3ff68d0de102b2acacc9b8616e659) under Xen 4.0 (F13)

Hi Boris et al,

I can confirm this problem. Same setup ( KV 2.6.32.15, Ubuntu 10.04 
server). evtchn is built-in, not a module. I manually tried to create 
the device node (mknod /dev/xen/evtchn c 10 62) but xenstored didn''t 
like that and after the failed start of xenstored /dev/xen/evtchn 
disappeard again. Is there a quick fix or should I downgrade?

cheers
  Paul

Backported to 4.0. Wasn''t sure about putting it into 3.4 yet?
I''m not too
fussed either way. It''s working okay for me and it is basically the
right
thing to do. :-)

It means back ported to xen-4.0-testing.hg ( it''s impossible to back
port  xen-4.0.0.tar.gz)

is OK.

Via my experience in meantime Xen 4.0 official release doesn''t have
either
origin/xen/stable or origin/xen/stable-2.6.32.x branch generating kernel
supporting it''s Dom0.

Backported to 4.0. Wasn''t sure about putting it into 3.4 yet?
I''m not too
fussed either way. It''s working okay for me and it is basically the
right
thing to do. :-)

We''ll get a 4.0.1 release out by end of the month. The next 3.4 release
is
further out, but I don''t think many users of that branch are going to
be
flirting with pv_ops dom0. If they are, they can always upgrade to 4.0
branch.

If it''s possible a separate patch for official xen 4.0 tarball  should
be created.
To provide an option of loading 2.6.32.15 under Xen 4.0 Release.
Otherwise,  it  appears to be useless. Specially on F13

Things are pretty bad in the meantime, if they use a pvops kernel. 
Maybe I should create a specific xen 4.0.0 branch?

Any chance of a hotfix for just this particular issue?

I''ve created 4.0.1-rc2-pre -  xen-4.0.1.fc13.src.rpm for F13
and rebuild & reinstalled xen''s rpms. Hot Hypervisor upgrade up to
4.0.1-rc2-pre
Kernel 2.6.32.15.

Pasi and myself noticed problems with VNC. Virt-installs run only text mode,
otherwise hang on top Ubuntu 10.04 Server. It DOESN''T happen on top of
F13
However,  at runtime on F13 :-
VNC console hangs for Lucid PV Guest at Xen 4.0.1 Dom0 (.15 kernel) on top F13
VNC console works for  F13 PV   Guest at Xen 4.0.1 Dom0 (.15 kernel) on top F13

It worked fine say for .12 or .13 kernels.
> Any chance of a hotfix for just this particular issue?

Looks like network communication problem with VNC.
It''s testing environment. But any customer watching  so unstable
picture, won''t be happy.

That''s more likely related to the network problems than the
evtchn/gntdev device problems.

Does doing "git revert -m 1 528ea798f02ccb03023e72cbda665ed5c3eec6b1"
and rebuilding help?

Yes, it helps.

The first time virt-install F13 PV DomU is running in VNC mode at Xen 4.0.1
(2.6.32.15)
Dom0 on top of Ubuntu 10.04 Server. Virt-install passed through phase of data
fetching
from Apache Mirror at Dom0 like it happened before (.14)

One issue still takes place at Xen 4.0.1 (2.6.32.15) on top F13 and Ubuntu
 10.04 Server as well.
Attempt to install ubuntu-desktop on Ubuntu 10.04 PV DomU results frozen VNC
Window. It doesn''t happen at Xen 4.0.0 ( 2.6.32.12) on top on any f13
or ubuntu 10.04
