Summing up, Ubuntu Server is a great server-oriented operating system that can be used in real life scenarios where the need for extremely reliable and stable server machines is a must. Thanks to MAAS, administrators can deploy multiple servers at the same time without to much hassle. With that said, today we will list the best Ubuntu Lets not waste too much time, have a quick look at It introduces numerable improvements to system stability, performance, power efficiency, and file system handling, and introduces support for newer Intel and AMD hardware.

It also introduces drivers for the Logitech G29 racing wheel and enables support for hardware features on some newer Toshiba laptops. A bigger and somewhat controversial change is the addition of support for the Zfs filesystem on Linux — the first version of Ubuntu to support it natively, out of the box.

Of particular note the xen hypervisor no longer supports 32bit only CPUs on the x86 architecture; 32bit Dom 0 running on the 64bit hypervisor is still supported.

When upgrading to Xen However, due to many dependencies, this is failing more often than not. Likewise, when libvirt is used to manage machines, the xend managed domains can be migrated into libvirt xml definitions by calling "sudo libvirt-migrate-xend-managed-domains". This is not done automatically for safety reasons.

This release of Ceph includes efficient erasure coding of data for cold storage and tiered pooling. Please refer to the upstream release notes for full details on upgrading. Due to incompatibilities in the emulated hardware, live migration of pc To migrate such a VM, you must install the kvm-ipxe-legacy package, and use the "-M pc Such VMs cannot be migrated to releases later than User emulation of arm64 binaries is now supported, and support for armhf and arm64 kvm-accelerated virtual machines is now available.

From If you are using a desktop image and being placed in low graphics mode, then switching to a new machine type, for instance pc See the upstream release notes for details of all features included in this release. Note that the openvswitch-datapath-dkms package is not compatible with the Linux 3. In addition to bug fixes and minor improvements, MAAS version 1. Zones : A Zone is arbitrary grouping of nodes.

Due to licensing problems, Debian dropped the PHP-supplied json module in Debian bug , replacing it with a compatible json module instead.

Ubuntu is aligned with Debian by default, and thus has picked up this change in The upgrade process will automatically pull in the new module. There have been claims of some edge case incompabilities in bug ; testing is advised.
