-------- Original Message -------- Subject: Building Xen on RHEL7 Date: Thu, 19 Dec 2013 18:57:22 +0000 From: Wei Liu wei.liu2@citrix.com To: centos-virt@centos.org
Hi all
This is a record of how I build Xen on RHEL 7. Hope this is helpful for people who want to package Xen for the upcoming CentOS 7. Basically it's not too much hassle to build Xen on RHEL 7. I'm in no way a packaging expert on RPM-based systems so I just list what's needed.
The Yum repo I'm using is the public beta mirror at https://mirrors.fedoraproject.org/publiclist/RHEL/7/x86_64/. I cloned Xen tree from git://xenbits.xen.org/xen.git and used master branch.
Dependences and requirements are listed by components.
# To make top level ./configure pass: yum install -y gcc python-devel acpica-tools libuuid-devel ncurses-devel glib2-devel libaio-devel yajl-devel zlib-devel
I also need to install dev86. I downloaded the latest version from http://www.debath.co.uk/dev86/ and installed it by hand. I noticed there's a dev86 package in Xen4Centos repo. We should be able to reuse that.
And we also need to do ln -s /lib64/libcrypto.so.1.0.1e /lib64/libcrypto.so otherwise configure complains it cannot find libcrypto while that library is actually there.
There's no markdown library in existing yum repo so some documents won't be built but that's not critical.
And optionally if you want to use oxenstored: yum install -y ocaml
# To build tools: ## To build hvmloader: yum install -y glibc-devel.i686
## To build qemu-xen-traditional yum install -y SDL-devel
## To build qemu-xen-upstream yum install -y pixman-devel
# To build stubdom yum install -y texinfo
By now you should be able to just run "./configure; make dist" in top level Xen source code directory without getting any error (hopefully). There's warnings though because gcc 4.8 has stricter check than previous versions.
I didn't build blktap, as RHEL 7 uses 3.10 kernel and Xen now has upstream QEMU, which should be able to cover all use cases. However default kernel only has frontend supports enabled (built as module), so we might need to alter its config or supply alternative Dom0 kernel.
Have fun and Merry Christmas.
Wei.
