Is your libxc uptodate? Do you have proper gnttab and evtchn entries in

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?

What distro? Perhaps there's something wrong with the udev setup?

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.

What distro? Perhaps there's something wrong with the udev setup?

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. :-)

Via my experience in meantime Xen 4.0 official release doesn't have either

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

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)

That's more likely related to the network problems than the
evtchn/gntdev device problems.
Does doing "git revert -m 1 528ea798f02ccb03023e72cbda665ed5c3eec6b1"

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
