x86_64 , linux-2.6.20-xen-r4 , Xen fail building

zavaxxx · n00b Joined: 09 Oct 2007 Posts: 3

I am following this xen guide:

http://gentoo-wiki.com/HOWTO_Xen_and_Gentoo

When I arrive at the point where i have to build the Domain U Kernel Configuration, i deselect

[ ] Privileged Guest (domain 0)
< > Backend driver support

but i get:

arch/x86_64/kernel/built-in.o: In function `intel_bugs':
early-quirks.c

.text+0xcfa4): undefined reference to `quirk_intel_irqbalance'
make: *** [.tmp_vmlinux1] Error 1

How/what can I do?

I'd like also to know if I have to use the gentoo xen sources or if i can use the latest vanilla kernel and then apply "the" xen patch.
Does a xen patch exist?

Thanks in advance and sorry for my bad english

I had the exact same problem.

I solved it by removing SMP from my Guest kernel...

Check out this thread.

yes thanks for the the tip, it works, but now i am in trouble again; I am following the guide linked in the first post, I am in

pwd
/usr/src/linux-2.6.20-xen-r6

and when I have to type the following command:

make world

I get the following error:

scripts/kconfig/conf -s arch/x86_64/Kconfig
***
*** You have not yet configured your kernel!
***
*** Please run some configurator (e.g. "make oldconfig" or
*** "make menuconfig" or "make xconfig").
***
make[2]: *** [silentoldconfig] Error 1
make[1]: *** [silentoldconfig] Error 2
make: *** No rule to make target `world'. Stop.

if I go in:

pwd
/usr/src/linux-2.6.20-xen-r6/_dom0

I get:
make -C /usr/src/linux-2.6.20-xen-r6 O=/usr/src/linux-2.6.20-xen-r6/_dom0 world
make[2]: *** No rule to make target `world'. Stop.
make[1]: *** [world] Error 2
make: *** [world] Error 2

What's wrong?

Thanks in advance.

hi, thanks for replying.

Yes I have the .config both in _dom0 and _domU

Can you explain how I can continue from the point where i am arrived?

or can you write how you reached your final result (xen working

)

thanks in advance.

Here is what I did (today in fact).

First add the following lines your ~/.bash_profile:

Hi

I also had the same problem and unchecking the SMP worked.

Now i have a question. Assuming that there is only one guest system working, does it has the ability to use mode than one cpu?

Since we disconnected the SMP, the answer should be no, but i'm not really sure.

If in deed the answer is no, this fix for the problem is kind of wrong or thre is some kind of bug related. Right?

Bye.

Hi

Well, thanks for the link.

For the next few days i have the xen idea stoped since I'm falling behind schedule in my work, but I will try again as soon as possible.

Bye
