[libvirt-users] Libvirt remote-client compilation for RHEL4
Hi, We are trying to compile Libvirt 1.02 from source for an RHEL4 target. Our virtualization hosts are running the fedora 17/ RHEL6 with the latest standard libvirt binaries. This is where VMs will be created. But our user/development machines are RHEL4 and we would like users to be able to use virsh/libvirt/python to control the Vms running on RHEL6/fedora17 remotely from the their RHEL4 machines. We are trying to compile a minimalist libvirt necessary on RHEL4 that would make remote control of VMs possible. Has anyone tried this? Any suggestions on what options to pass to ./configure to minimize what needs to be compiled for this purpose? Or on RHEL 4? Thx, Sarvi
I am using the following configure to minimize dependencies and avoid anything unrelated to getting a libvirt remote client going.

[your mailer doesn't wrap long lines, which makes it harder to read]
./configure --with-python --with-apparmor=no ...
You can also spell --without-apparmor instead of --with-apparmor=no (and so forth). Many of those options are automatically disabled if you use --without-libvirtd, or if a particular library is detected as not installed; it might be worth minimizing your configure line to prune options that don't make a difference. The resulting summary printed at the end of the configure run will show you which pieces were detected as enabled or disabled.

You'll have to debug this one yourself - something in your old system header doesn't like the order in which other files were included.

This one's a trivial fix. In fact, it looks like we've fixed a similar problem for other platforms before, given that commit de53eff fixed the same problem for virShrinkN.

BTW, does the following work for you? --prefix=/home/berrange/libvirt --localstatedir=/var --sysconfdir=/etc For me make succeeds, but "make install" fails. I got around it by changing src/remote/remote_driver.h to the following and got things to work.

I also found this thread relating to compiling clients for RHEL4 from 2011 https://www.redhat.com/archives/libvirt-users/2011-January/msg00108.html
Attached is a patch which makes 1.0.3 compile on RHEL-4. Apply to a fresh 1.0.3 libvirt codebase, and then run something like this:
# ./configure --without-libvirtd --without-python --without-numactl --without-vbox --prefix=/home/berrange/libvirt --localstatedir=/var --sysconfdir=/etc # make # make install
You could probably also pass --without-esx --without-parallels and --without-vbox
I'll get this patch applied to GIT for the next release

Hi, We are trying to compile Libvirt 1.02 from source for an RHEL4 target.
Good luck. Unfortunately, upstream libvirt does not target RHEL4 (we have only tested that upstream libvirt can build on RHEL5), so there are probably lots of gotchas, and you will have to do lots of legwork yourself. Feel free to submit patches on what you changed to get things to work.
We are trying to compile a minimalist libvirt necessary on RHEL4 that would make remote control of VMs possible.
So all you need is the libvirt.so with RPC support, and then the python bindings. Use of --without-libvirtd will force a client-only configure, which should help. Any further compile issues are probably related to really old portability problems in your system headers. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
