Installing Xen 4.0.1 from Source on Ubuntu 10.10

Question

I'm trying to install Xen 4.0.1 from Source on Ubuntu 10.10 Server Edition. I started with a clean machine and followed the instructions from https://help.ubuntu.com/community/Xen.

So I installed the packages mentioned there with: sudo apt-get install gettext bin86 bcc libc6-dev-i386 iasl texinfo git

When making the source with make world I get this error:

+ git clone -o xen -n git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-pvops.git.tmp

fatal: git checkout: branch xen/stable-2.6.32.x already exists
make[3]: *** [linux-2.6-pvops.git/.valid-src] Error 128

Does anybody have an idea what i can do?

Answer 1

edit the following file: ./buildconfigs/src.git-clone (under xen folder)

edit the following line (line 29 in my config)

(cd $(LINUX_SRCDIR).tmp; git checkout -b $(XEN_LINUX_GIT_LOCALBRANCH) $(XEN_LINUX_GITREV) ); \

to look like

(cd $(LINUX_SRCDIR).tmp; git checkout ); \

Answer 2

I also need to know how to fix this issue.

It appears that there is already a file named xen in the xen directory where git is trying to check out to...

+ git checkout -b xen/stable-2.6.32.x **xen/xen/stable-2.6.32.x**
fatal: git checkout: branch xen/stable-2.6.32.x already exists
