[libvirt] libvirt on x64

[Tavares, John]

Hi Eric,

Thanks for getting back to me.  This may have been a system running SLES 10.2 (2.6.16.60-0.21-xen (SUSE Linux Enterprise Server 10 (x86_64))).

As to RHEL 5.5, it seems to come with 0.6.3 by default.  I am trying to find a system running a 64-bit kernel, but I have yet to find one in my environment.  Could you check to see if you have access to one to see if the same holds true as well??

My end goal is to have a single 32-bit application use libvirt on both x86 and x64.  I dislike having to ask customers to install another package on their system just for this.  I would think that both should be installed by default.

Thanks.

John

Which distro?  Also, libvirt 0.3.3 is rather old; we are now at 0.8.2
upstream, and Fedora 13 includes 0.7.7.

Generally, on an x86_64 platform that uses rpms, the 32-bit libraries
are available as a separate rpm.  For example, I'm running Fedora 13 on
an x86_64 host; so I would use 'yum install libvirt-devel.i686' to get
the 32-bit development libraries.
