Beyond the features of the Linux 3.0 kernel
already talked about on Phoronix, there's another big milestone hit in this next kernel release beyond changing up the versioning scheme. The Linux 3.0 kernel will have full Dom0 and DomU support for Xen virtualization.
As mentioned on the Xen Blog
, "The fantastic news is that Linux 3.0 will have everything necessary to run Xen as both as a management domain and as a Xen guest."
This has been a long process getting all of the Xen bits merged in the upstream Linux kernel, but it's a point that's finally been reached. Oracle has blogged
about this as well in more detail as well as notes from Citrix
Time for new Linux KVM vs. Xen virtualization benchmarks?
