When xend is starting, it logged this:

Someone said that it is because the kernel option CONFIG_XEN_DEV_EVTCHN should be set as 'y' but not 'm', so I checked my linux kernel configuration, and found it is set as 'y'.

I can find /sys/bus/scsi/devices/host0/target0:0:0:0/0:0:0:0/vendor, or /sys/bus/scsi/devices/host0/target0:0:0:0/0:0:0:0/scsi_device/0:0:0:0/device/vendor, but definitely no  /sys/bus/scsi/devices/host0/vendor

Why this happen? And how can I fix this?

Thanks.

Hi,
Yes, I've did this
echo "none /proc/xen xenfs defaults 0 0">>/etc/fstab
to add xenfs mount entry just after I installed xen¡£

Actually I was following this XenParavirtOps direction here:
http://wiki.xensource.com/xenwiki/XenParavirtOps to install and configure xen 4.1.0 with kernel 2.6.39

I did all of those checks:

# cat /proc/misc
¡¡
60 xen/gntalloc
61 xen/gntdev
62 xen/evtchn
¡¡

#ls -la /dev/xen
total 0
drwxr-xr-x  2 root root    100 2011-04-18 20:36 .
drwxr-xr-x 12 root root  13780 2011-04-18 20:36 ..
crw-rw----  1 root root 10, 62 2011-04-18 20:36 evtchn
crw-rw----  1 root root 10, 60 2011-04-18 20:36 gntalloc
crw-rw----  1 root root 10, 61 2011-04-18 20:36 gntdev

But "lsmod | grep -i xen" shows nothing, and I was told that "module xen_gntdev/xen_evtchn not found" when I try to load these modules by "modprobe xen-gntdev/xen-evtchn".

I also  found that when "make modules_install" executed, it didn't install any module under /drivers/xen/, but I don't know why.

In the kernel .config file, I can't find some item the Pv_ops direction mentioned, such as CONFIG_XEN_PCI, CONFIG_XEN_KBDDEV_FRONTEND, CONFIG_XEN_BLKDEV_BACKEND, and can't find the definition of these options(grep returns nothing), so I think they might be cancelled in new 2.6.39 kernel.

Where did you get the 2.6.39 kernel from?

Did you turn on CONFIG_PARAVIRT=y

I got the 2.6.39-rc3 kernel full source from http://www.kernel.org.
And CONFIG_PARAVIRT is turned on.

Here is the steps I configure the kernel:
1. Processor type and features
High Memory Support--->
64GB
(Then I can see PAE and some xen related options)

2. Processor type and features
--- Paravirtualized guest support--->
[*]Xen guest support

3. Device Drivers
Xen Driver Support--->
(All turned on by default)

4. Device Drivers
Metwork device support--->
<*> Xen network device frontend driver
<*> Xen backend network device

5. Bus options
<*>Xen PCI Frontend

The 2.6.39-rc3 does not have the blkback driver in. There is a version

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git #master

that has that one.

Ok, so that is there.

OK, so you have the right version of Dom0. What about the version of
Xen-unstable? Are you compiling it from scratch?

I've found some mistakes in my configuration of the linux kernel, and I can load those modules(xen-gntdev, xen-gntalloc, xen-evtchn) now.
And I've fixed the problem of missing scsi devices under /sys/bus/scsi/devices/ directory. I learned that /etc/init.d/xencommons should be started before starting xend.

I'll try to create new pv guests next step.
Thank you for your help.

One more question: 
Does missing block device backend driver cause any problem?
