Re: how to transfer an LVM Guest OS on KVM Lucid to another server

This some how is what I am not clear with and trying. If you want it to be really fast, make sure that the VM backing stores are shared between the two servers, Ok and at the same pathnames on both. You mean to say NFS or iSCSI type of thing, With maverick you can ask libvirt to move the backing store for you. Ok that would be released in a week so I have to wait till then, but still I want to explore this thing. -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

server rebooting frequently how to diagnose
I am having a small problem on my Power Edge server. It is PowerEdge R710. It is rebooting frequently I am having a virtuallization setup over it. Some one a long time back had told me about some way to make a log on power edge via a utility which can have some sort of dumps. Which I can send to Dell for analysis if any one is able to understand what I am saying then give me a link.

will go back divide the loopbits by 2 as a result of (right shift)
and the OR operation will make sure that the value which is divided by
2 of loopbits gets added to loops_per_jiffy
will enter the delay loop and in this case if this time the if
condition is true then
the result of loops_per_jiffy = ~loopbit
is
loops_per_jiffy = loops_per_jiffy AND (~loopbit)
where taking complement of loopbit as above makes it negative (not
sure on this part)
and the result is the value is subtracted (as it was more than required value)
and then loopbit is again divided so added and this cycle will continue until
exact value of loops_per_jiffy is calculated.

but such a logic which is used above
is there any more example some where?

Doing this for small subroutines is resource consuming.So it is a good
practise among kernel developers do declare functions inline when it

saving the stack,program counter flag registers and other registers
which are being related to the program in execution.
By using the word in laymans language I will say that part of code
(function ) is actually written where ever the function call is made.
For example following program
example1.c
#includestdio.h
inline function ingen (X1,X2)
{
does some thing some thing
return c;
}
function b( )
{
step = function ingen ();
}
main()
{
b ();
}
If you were to execute above code
call to function ingen () via function b() would replace the
function ingen() by the code inside function ingen().
If you would not have declared function ingen as inline function then
the CPU would jumped to some memory location where function ingen() is
actually residing and then executed.
In this case CPU just have to insert that code what ever function
ingen() does when ever a call to function ingen() is made via function
b().
Or which ever function in the code calls function ingen().
If the keyword static is added so that if the same function has been
used at any other place then it should not affect the other
files.Meaning the word static before a function makes its scope
limited to that file only.
If you have another program example2.c and compile
cc example1.c example2.c
then functions in exampl1.c would be available to example2.c and vice
versa but use of word static restricts the function in their
respective files.
i.e. if example1.c has a static function then it will not be available
to example2.c
Since Linux kernel is made up of C and to make sure functions with
similar names(if any) exist then they are not conflicting it is a good
practice to declare a function as static.
Declaring it inline reduces the overhead that CPU would have to do in
actually calling a function.
To have more digging about this you need to understand mechanism of
function call as what does
processor do when a function call is made.
Clearly if you have a large code to execute the
instruction is in memory and it has to come to cache so if you have
large code and you declare that as inline it has disadvantage that
cache miss will more.
What I wanted to
say is if you have a function is used at 10 places and you declare it
inline 10 times then there would be cache miss more (because that
inline part of code would not be in cache) and this will
have disadvantage.

Hi,
I am new to kernel development.
So after being able to have some basic understand of some things I just went
through source code.
I was going through a file known as
linux-2.6.34/kernel/timer.c and found following code.
I want to understand what is it doing.
What should I be reading to be able to understand it?
static inline void
timer_set_base(struct timer_list *timer, struct tvec_base *new_base)
{
timer-base = (struct tvec_base *)((unsigned long)(new_base) |
tbase_get_deferrable(timer-base));
}
What static does is to create a label for a certain global memory
chunk and give that a value at compile time, plus not making it
available to the linker.
Look at these examples
static int mystatic = 6;
int main(void)
{
return 0;
}
Generated ASM is as follows:
Code:
.file static2.c
.data
.align 4
.type mystatic, @object
.size mystatic, 4
mystatic:
.long 6
.text
.globl main
.type main, @function
main:
pushl %ebp
movl%esp, %ebp
movl$0, %eax
popl%ebp
ret
.size main, .-main
.ident GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)
.section.note.GNU-stack,,@progbits
Compare that with declaring the global variable as non-static:
Code:
int mynonstatic = 6;
int main(void)
{
return 0;
}
Code:
.file nonstatic2.c
.globl mynonstatic
.data
.align 4
.type mynonstatic, @object
.size mynonstatic, 4
mynonstatic:
.long 6
.text
.globl main
.type main, @function
main:
pushl %ebp
movl%esp, %ebp
movl$0, %eax
popl%ebp
ret
.size main, .-main
.ident GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)
.section.note.GNU-stack,,@progbits
The only difference is that in the non-static case, there's the .globl
mynonstatic that makes that symbol available to the linker.
Now, careful observation will make you notice that both global
variables are declared as labels, exactly the same way as main is. ASM
doesn't really distinguish between functions and variables (the
@function and @object thing is just an optimization gcc does): all
there is memory addresses that you conveniently can refer to with a
label. So, when you declare a function static, what will happen is
exactly the same: the function is given a value (its code) and make it
unavailable to the linker... exactly what was done to the variable.
Here you have the C and ASM for a static function:
Code:
.file stat_func.c
.text
.type something, @function
something:
pushl %ebp
movl%esp, %ebp
movl$0, %eax
popl%ebp
ret
.size something, .-something
.ident GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)
.section.note.GNU-stack,,@progbits
Again, the value for something is its code, it's a global value but
not available to the linker because there's no .globl something.
What about local static variables? Actually, the idea of local
variables is lost when compiling C to ASM. What you have is a global
stack that each function is in charge to clean up when returning...
therefore making its local values no longer available outside the
function... but place a jmp and the value will be available. What
happens with static variables is that the static again sets up a value
at compile time and makes the symbol unavailable for the linker... as
you'll see here:
Code:
int main(void)
{
static int mystatic = 6;
return 0;
}
Code:
.file static.c
.text
.globl main
.type main, @function
main:
pushl %ebp
movl%esp, %ebp
movl$0, %eax
popl%ebp
ret
.size main, .-main
.data
.align 4
.type mystatic.1248, @object
.size mystatic.1248, 4
mystatic.1248:
.long 6
.ident GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)
.section.note.GNU-stack,,@progbits
The only difference here is that the .data section has been placed
*after* the main rets (a kind of return you have in ASM...)... ASM
indentation is awful here, but actually main ends at the ret, not at
the mystatic.1248 label. Ok, I'm not sure why the name is mangled
but it's clear that the variable is declared as global even when we
declared it as local in C. What will happen is that the C compiler
will restrict the usage of that symbol to the main function, but you
clearly see that it's just a way to create the illusion of locality...
It's actually a global and that's why its value is persistent across
the program's execution.
So, in summary, it seems that the real effective meaning (I don't care

Re: linux/module.h does not exist
No It did not worked I tried what you said.
Here is the new program.
If possible just copy paste the program and try to run.
#include linux/kernel.h
#include asm/syscalls.h
#include linux/module.h
#include linux/unistd.h
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
asmlinkage int alt_exit_function(int err_code)
{
printk(Sys_exit called with err_code=%d\n,err_code);
return main_sys_exit(err_code);
}
int init_module()
{
main_sys_exit=sys_table[__NR_exit];
sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{
sys_table[__NR_exit]=main_sys_exit;
}
Following way I tried to do it.
gcc -I /usr/src/linux-headers-`uname -r`/include -I
/usr/src/linux-headers-`uname -r`/linux -Wall -DMODULE -D__KERNEL__
-DLINUX -c sample2.c
and following errors I got
http://pastebin.com/ZGRD8cC3
any more guess?

I wont 2 cents :)
It did not worked
Following is new program
#include linux/kernel.h
#include sys/syscalls.h
#include linux/module.h
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
asmlinkage int alt_exit_function(int err_code)

sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{

}
Following is way I compiled
gcc -I /usr/include/ -Wall -DMODULE -D__KERNEL__ -DLINUX -c sample2.c
and following are the errors
http://pastebin.com/u3mPhfUf
Then I compiled it also in following way
gcc -I /usr/src/linux-headers-2.6.28-11-generic/include/linux/ -Wall
-DMODULE -D__KERNEL__ -DLINUX -c sample2.c
and got following errors

So 2 cents :)
any how this is the original link where I was trying the code

i'm just catching up with this thread and, if i read it correctly,
the goal is to build a loadable kernel module using the proper

Yes yes right
but
i'm not sure i see the value in tha
I was reading and trying to understand the programs given in the Linux
Magazine to which I have posted the links.
t -- why not just build the module
using all of the compilation infrastructure built into the kernel
source Makefile and accompanying build structure?
Sure here is my Makefile
ifeq($(KERNELRELEASE),)
KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
.PHONY: build clean
build:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

rm -rf modules.order Module.symvers
else
$(info Building with KERNELRELEASE =${KERNELRELEASE})
obj-m := sample2.o
endif
I did make but I got following error
Makefile:1: *** missing separator. Stop.
I will try the Makefile approach also.
Since till now I just was trying an approach the author had described
so had not tried Makefile.
not trying to market, but i explain how to do that here:
http://crashcourse.ca/introduction-linux-kernel-programming/introduction-linux-kernel-programming
:)
in the first few lessons, which are publicly available to everyone.
granted, you *can* reproduce all of that manually if you want, but i
don't see the point in making this any more difficult than it has to
be. of course, if i've misunderstood what this thread is about, you
can ignore all this. :-)
No if interested do stay in this thread.
I am not sure if the program in magazine is wrong or correct
or what did the author tried to convey?
Specially the asm_linkage part what is the author trying to explain the readers.
p.s. specifically, i demonstrate how to build your first kernel
module here:
http://crashcourse.ca/introduction-linux-kernel-programming/lesson-4-writing-and-running-your-first-kernel-module
again, that lesson is publicly available to everyone.
Ya I found it quite useful.

[squid-users] rtmp redirection at gateway
Hi, is it possible to re direct the requests coming at gateway from internet in following format rtmp://site1.mydomain.com rtmp://site2.mydomain.com rtmp://site3.mydomain.com rtmp://site4.mydomain.com by squid to internal servers which are actually hosting site1.mydomain.com site2.mydomain.com or things like this. This is not a load balancing thing all of them are different server with different contents. -- Tapas http://mightydreams.blogspot.com http://wiki.xensource.com/xenwiki/Xen_on_4_app_servers

multiple streaming servers in a cloud
Hi, I need some help. I have multiple video streaming servers running on some machines internally on LAN. For different subdomains. i.e. site1.mydomain.com site2.mydomain.com site3.mydomain.com site4.mydomain.com I am not doing any load balancing these are different websites. The video streams on these are served when a request comes as rtmp://site1.mydomain.com rtmp://site2.mydomain.com rtmp://site3.mydomain.com rtmp://site4.mydomain.com I want to have all these servers hidden from the end user. These requests be forwarded by some thing which is in front of all these four servers. What do I need to handle in this case ? For handling HTTP requests in this case I use Apache Reverse Proxy but for rtmp requests I am not clear as which direction to proceed. If squid can help me in this case then let me know. Or nothing such exists in squid to handle this scenario ? -- Tapas

multiple streaming servers in a cloud
Probably some one on this list may give me some idea to which direction I should look or think. This question is not for kernel development but it is a problem I am facing. I have multiple video streaming servers running on my LAN. For different subdomains. i.e. site1.mydomain.com site2.mydomain.com site3.mydomain.com site4.mydomain.com All the above websites have different content and are different websites. The front end to the world is apache2 on a server which has public IP. To be able to reach the streaming server I embed a javascript in HTML pages as follows Code: embed . var=rtmp://site1.my_domain.com the problem is the website are many site1.mydomain.com site2.mydomain.com site3.mydomain.com site4.mydomain.com each on a separate server. Each of these four have their own streaming servers the front end to each of these four is apache running on gateway If I run rtmp on each of the subdomains at a different port how will I make sure a request such as rtmp://site1.mydomain.com rtmp://site2.mydomain.com goes to their respective servers. from the front end server from gateway. What do I need to handle in this case ? For handling HTTP requests in this case I use Apache Reverse Proxy but for rtmp requests I am not clear as which direction to proceed. What I want is if I embed a code in javascript as rtmp://site1.mydomain.com then request for rtmp://site1.mydomain.com rtmp://site2.mydomain.com goes to the server on LAN which has site1.mydomain.com site2.mydomain.com respectively. The gateway is Linux Server. Which redirects to these websites via Reverse Proxy at apache what more I need to put in my vhosts at gateway.

Re: multiple streaming servers in a cloud
Ok I got some solution so posting here it should help some one else. To do with a single Public IP address. It requires either port redirection or layer7 firewalls/reverse proxies such as SOCKS or perhaps Squid. One way is to run these streaming servers at different ports as rtmp://site1.mydomain: --- your public IP address port which then hits the firewall and is redirected: publicIP port - privateip 192.168.0.1 port1935 rtmp://site2.mydomain: --- your public IP address port which then hits the firewall and is redirected: publicIP port - privateip 192.168.0.2 port1935 Simple to do and works well. But in this case when I would like to try Layer 7 proxies / firewall have to look at the url requested and then So if some one has got close to this one some idea let me know now. -- Tapas http://mightydreams.blogspot.com http://wiki.xensource.com/xenwiki/Xen_on_4_app_servers -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

[us...@httpd] Apache as front end for rtmp stream
I am having a website which is running on Zope. I am using Apache as a front end to that Zope website. On the same server where Zope is running I am having a streaming server Red5 running on it. My communication to the Zope website from outside world is via front end Apache only. To be able to reach the streaming server I embed a javascript in HTML pages of Zope website which is running Plone as follows embed . var=rtmp://m http://ocw.openitup.iny_domain.com My problem is a request for mydomain.com is handled via front end Apache on which I have redirected this to Zope. Now in case of rtmp streams which are coming in form of rtmp://mhttp://ocw.openitup.in y_domain.com is it possible to do some thing in Apache so that request to video streams coming from outside to be redirected to Red5 on internal server on LAN. So our communication with world is via Apache only. In this situation how can apache redirect to a Red5 application or say a stream on rtmp. If you some has some clue on this then let me know. -- Tapas http://mightydreams.blogspot.com http://wiki.xensource.com/xenwiki/Xen_on_4_app_servers
