Kernel 2.6.23

Linux kernel 2.6.23 was released yesterday. Of note for virtualization is the addition of both Xen and lguest (see an introduction to lguest) support.
Xen support is based on the relatively new paravirt_ops interface, it is limited to 32-bit and guest only (no dom0 support).
Improvements have been made on the KVM front as well – guest SMP support and support for machines without PAE.
One non-virtualization feature that caught my eye is that the ext filesystem (ext4 specifically) finally has support for 32,000+ subdirectories – yes, I’ve seen braindead apps that need that. Of course it will be years before RHEL includes ext4 and most other distributions already have filesystems without this limitation.
