I am trying to make = xen-virtualization system

 

My machine = is

CPU : Intel Xeon E5520 * 2
RAM : DDR3 1333 2GB * 6
HDD : 500GB SATA * 4 (RAID 10)

 

CentOS5.3 Kernel = – 2.6.27.29-0.1.1 (original was 2.6.18-128 and I = upgraded)

Xen – 3.4.2  (http://www.g= itco.de/repo/GITCO-XEN3.4.2_x86_64.repo)

 

 

When I boot my computer, it = shows some messages like below;

 

Starting xend: Nothing to = flush

FATAL : Module netloop not = found

FATAL : Module netlbk not = found,

FATAL : Module blkbk not = found,

FATAL : Module blktap not = found,

 

And when I reboot It starts to = hang.

 

As I surveyed, from Xen 3.3 and = later, we should install above modules in Xen-kernel, not separate = modules.

So I set those modules install = in xen-kernel.

(I mean, when we set menuconfig = (make menuconfig), it should be [*], not [M])

 

However, when I look through the /etc/init.d/xend source, they have =A1=B0modprobe=A1=B1 sentence.

 

So I changed all those modules = as =A1=AE<M>=A1=AF in = menuconfig.

After this, netloop and netbk = was installed, however, blkbk and blktap was not installed.

 

So, I installed netloop and net = bk as Module, and blkbk and blktap in xen-kernel.

The, I boot my computer, it = shows some messages like below;

 

Starting xend: Nothing to = flush

FATAL : Module blkbk not = found,

FATAL : Module blktap not = found,

 

And when I reboot, it starts to = hang again!

 

After that, I commented out = =A1=B0modprobe blkbk=A1=B1 and = =A1=B0modprobe blktap=A1=B1 in = /etc/init.d/xend file., then it doesn=A1=AFt show those = messages,

However, it hangs = again.

 

When I boot my machine without = xend, then it does not show hang.

 

And I did googling and I found = that other people have same problem like me, and it is caused by = blktap.

And some people give some = solutions and patch for blktap, however, those kernel version or xen version is = different from mine, So I could not apply them to my = computer.

Is there any solution or patch = files for this problem?
