in thread C headers not found when installing Sys::Virt on CentOS

There are many such sites, but even my favorite, pkgs.org, is seriously lacking in search capabilities, so a search for Sys::Virt will come up empty.

Therefore, I'd recommend just googling for rpm Module::Name instead.

Note however that in this case you could have just searched with yum search Sys::Virt on your machine itself.
