Recently I switched to Ubuntu as the primary operating system on my desktop machine. As part of the switch, I wanted to install Xen to virtualize some additional operating systems. Xen provides very good performance when virtualizing Linux distribution…

Thanks for the tutorial.
When I was compiling my kernel I hit this error when I executed the “make” command
————————-
CC [M] drivers/net/sfc/falcon.o
drivers/net/sfc/falcon.c:2928: error: redefinition of ‘falcon_dimension_resources’
drivers/net/sfc/falcon.c:2825: note: previous definition of ‘falcon_dimension_resources’ was here
make[3]: *** [drivers/net/sfc/falcon.o] Error 1
make[2]: *** [drivers/net/sfc] Error 2
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2

Any idea how to get rid of this error and move forward?
Any help regarding this issue would be really helpful.

Thanks,

how to slove？

You only typed a few Is there a list currently that you know of for all the modules available and their specified names or calls in this file?

any time and help is appreciated

If you compiled the Xen net, block and usb backend drivers as modules, you will probably want to load them by default by adding them to your /etc/modules file:
view source
print?
1 # /etc/modules
2 …
3 # These modules are required for Xen DomUs to work
4 netbk
5 blkbk
6 usbbk

That works fine. But then I type:
make

And it gives me an error stating:
awk: line 2: function gensub never defined
scripts/Makefile.build:82: *** ‘Your awk program does not define gensub. Use gawk or another awk with gensub’. Stop.
make: *** [scripts_basic] Error 2

From what I read, I’m thinking I have a problem with awk. I checked the man pages for awk, but all I had was mawk.

So I typed:
sudo apt-get install awk

That displayed a page where it asked for me to specify whether I wanted original-awk, gawk, or mawk. I told it original-awk. So it installed. I checked the man page for awk… and again only mawk displayed.

So is it something else or is my awk being like… overwritten by mawk?

Thanks!!!

It sounds like your problem is related to root permissions. You should do everything as a normal user (not root) except when I prefix my command with sudo. This means you shouldn’t have used sudo to untar the files, etc. It sounds like you don’t have permission to modify the source files as an ordinary user when running patch. This would be the case if you used sudo to untar the source files.

I’d suggest starting over in a directory inside your home directory, or /tmp, or somewhere else where your user has write access. Untar the files without sudo and try the patch command again.

Hope that made sense :/

So… hmm. Well when I type sudo in front of the entire for loop:

sudo for i in `ls ../xenpatches-v10_2.6.31.8/`; do patch -p1 < ../xenpatches-v10_2.6.31.8/"$i"; done

it says:

bash: syntax error near unexpected token `do'

So I removed the do, and I got a similar response as above, but with the `done'

So again I removed that, but now it does the exact same thing as before.. where it says:

File to Patch:

BTW, I checked my patch version, and its 2.5.9

Should I upgrade my patch version? and how would I do that? I acquired the patch command from typing:

sudo apt-get install patch

I assumed that would've installed the latest release… I guess I was wrong.

Thanks again for your help.
