Coupling iptables Rules with Virtual Machine Configuration

Karl Wirth has been kicking[1] "around an idea before with some of you about iptables...basically being able to have iptables rules that are associated with the metadata around a particular vm, then apply those to the host iptables when the vm is spun up or migrated to that host."

sVirt 0.20 Patch Request for Comments

James Morris announced[1] "the release of v0.20 (FWN#149[2]) of sVirt, a project to add security labeling support to Linux-based virtualization. I'm hoping to be able to propose an initial version for upstream merge within the next few minor releases, tasks for which are being scoped out in the new TODO list[3]."

"If the current release passes review, the next major task will be to add dynamic MCS labeling of domains and disk images for simple isolation."

Daniel P. Berrange said "this patch all looks pretty good to me from a the point of view of libvirt integration & XML config representation."

Latest libvirt on RHEL and CentOS 5.2

Marco Sinhoreli needed[1] libvirt 0.5.x for testing oVirt on RHEL 5.2. Marco wondered what was necessary to update from the 0.3.x version available for RHEL.

Soon after, Daniel P. Berrange "uploaded[2] a set of patches[3] which make libvirt 0.5.1 work with RHEL-5's version of Xen. Basically we have to tweak a few version assumptions to take account of fact that RHEL-5 Xen has a number of feature backports like the new paravirt framebuffer and NUMA support."

"Of course running a newer libvirt on RHEL-5 is totally unsupported but hopefully these will be usful to those who absolutely need this newer libvirt and don't mind about lack of support."
