http://linuxvirtualization.com/ en-us 40 Linux Virtualization comments <p>Linux kernel 2.6.23 was released yesterday. Of note for virtualization is the addition of both Xen and lguest (see <a href="http://lwn.net/Articles/218766/">an introduction to lguest</a>) support.</p> <p>Xen support is based on the relatively new paravirt_ops interface, it is limited to 32-bit and guest only (no dom0 support).</p> <p>Improvements have been made on the <span class="caps">KVM</span> front as well &#8211; guest <span class="caps">SMP</span> support and support for machines without <span class="caps">PAE</span>.</p> <p>One non-virtualization feature that caught my eye is that the ext filesystem (ext4 specifically) finally has support for 32,000+ subdirectories &#8211; yes, I&#8217;ve seen braindead apps that need that. Of course it will be years before <span class="caps">RHEL</span> includes ext4 and most other distributions already have filesystems without this limitation.</p> Wed, 10 Oct 2007 09:19:00 EDT <a href="/articles/2007/10/10/kernel-2-6-23">Kernel 2.6.23</a> <a href="/articles/2007/10/10/kernel-2-6-23">Kernel 2.6.23</a>
