[libvirt] Looking for libvirt for RHEL 6.1 to provide Memory related metrics.
Hello All, Can some one let me know if we have the latest libvirt version for RHEL 6.1 which would provided me Memory related counters/metrics. The latest libvirt which I found was on Fedora. Any pointer or expected dates of libvirt release on RHEL would be highly appreciated. Thanks and Regards, _____________________________________________________________________ Kallol Roy "Be kinder than necessary, for everyone you meet is fighting some kind of battle."

If you have specific questions about libvirt on RHEL, you may be better off opening a support ticket with Red Hat. Since each release of RHEL picks a given libvirt version, and then only backports patches that don't bump ABI compatibility into that version, you will have to work it out with Red Hat whether you can get your desired feature backported to RHEL 6.1, or whether you should instead upgrade to newer RHEL. Otherwise, you can just rebuild any version of libvirt that you desire to run on RHEL 6.1, although by doing so, you no longer get Red Hat support on your use of libvirt if your self-build has problems. Meanwhile, RHEL 6.2 is available for the public, with a newer version of libvirt (v0.9.4 plus patches), and RHEL 6.3 beta has been announced (v0.9.10 plus patches). Future release dates and libvirt versions in those releases are anyone's guess. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

Hello Eric, It was indeed kind of you to revert back with the clarification. Thanks a ton. Got couple of more queries which I am mentioning below: Consider me as a new CU who would be using KVM on RHEL, what would be your suggestions (like which version of RHEL and libvirt) should I be installing/upgrading in order to get the metric/counters for resources like CPU, MEMORY, DISK and NIC (for guest and host).

Thanks. Next, can you convince your mailer to wrap long lines? Also, this list tends to frown on top-posting.

Hello Eric,
It was indeed kind of you to revert back with the clarification. Thanks a ton. Got couple of more queries which I am mentioning below:
Consider me as a new CU who would be using KVM on RHEL, what would be your suggestions (like which version of RHEL and libvirt) should I be installing/upgrading in order to get the metric/counters for resources like CPU, MEMORY, DISK and NIC (for guest and host). Given my production environment is on RHEL 6.1/5.7 Can you give an example of an environment (configuration) which would meet my requirement?
I reiterate my earlier advice - if you are using RHEL, your best course of action is to take full advantage of your RHEL subscription and open a support ticket with Red Hat, rather than asking random developers on the upstream list. The RHEL support team knows exactly what the RHEL build of libvirt supports, including which features have been backported into the RHEL build when compared to the same version number from the upstream tarball.
Next is do I get any information as which counters/metrics are being enabled with each of the new version of libvirt being released? The latest rpm I do see on the ftp://libvirt.org/libvirt/ is for Fedora. How about the last one (.gz) Can it be installed on Linux?
Yes, we strive for upstream libvirt to be compilable on all builds of GNU/Linux systems. But when you use the upstream version of libvirt on RHEL, you no longer have the advantage of RHEL support for libvirt - you are somewhat on your own figuring out how to take advantage of the newer features that are present in your self-built libvirt. This list will try to answer questions, but the people on this list are not a paid support team; even the redhat.com addresses on this mailing list tend to be in a different group at Red Hat than what you would interact with when opening a support ticket.
libvirt-0.9.12-1.fc16.src.rpm libvirt-0.9.12-1.fc16.x86_64.rpm libvirt-0.9.12.tar.gz
Is a particular libvirt version tightly coupled to a RHEL version?
The RHEL-supported version of libvirt is specific (after all, the point of paying for a RHEL subscription is that you get a stable, well-tested version, with bug fixes backported, rather than chasing an unstable goal of the latest upstream). But that does not mean that you cannot run newer libvirt on RHEL if you build it yourself.
Can I use "yum update" to upgrade my libvirt libraries to something latest?
If you use supported RHEL upgrade methods, then you will have the latest supported RHEL build of libvirt; the version number may be smaller than the latest upstream number, but you can be assured that critical bug fixes are backported into the RHEL build.
Currently my environment which RHEL 6.1 has the following libvrt libraries and I would like to upgrade to a higher version of libvirt. If you can let me know your expert opinion.
RHEL 6.1 is a bit outdated; RHEL 6.2 is the latest stable release, and RHEL 6.3 is in beta. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
you can get the libvirt rpm package for el6.3 from here: http://veillard.com/libvirt/6.3/
