Overview of the first few new things I found in the Oracle VM 3.0.1 dom0 install.
- Kernel version bumped to 2.6.32
- Xen version 4.0.1
- 170 MB compressed iso
- disk usage 588MB
- Installer supports Vlan tagging for management interface (802.1q)
- fancy (and useful!) status screen upon boot – no need to jump into submenus to find important info
- xl tmem-set commands are available (boot with xen option “tmem”)
- multipath enabled per default (including a config for quite new stuff like Fujtisu Eternus)
- Infiniband support is loaded, Kernel modules for stuff like RDMA are loaded!
- Infiniband userpace stuff seems to need installation
- libvirtd is still disabled per default*
- ksplice seems to be not yet in (for instantenous dom0 kernel updates) – but of course with live migration this is not highly important.
On the download site you’ll find the ISOS for 64bit (only), the iso with all sources and of course the manager.
Very bad is that there’s no SDK available yet. I figure it’ll show up over the next days.
All over it made a very nice first impression – a very balanced and careful update. The new OVM Manager release will be more interesting to look at, to find out which features made it in, and which ones are left to be added in 3.1. Many of those were really promising, i.e. automated power management for hosts to couple power management and load balancing. This would be really exciting.
