Oracle Linux 10 for 64 bit Arm with its root filesystem on LVM, a free RHEL 10 compatible base for Azure Cobalt 100 virtual machines.
Oracle Linux 10 is Oracle's free and freely redistributable enterprise Linux distribution, binary compatible with Red Hat Enterprise Linux 10 and supported by Oracle to June 2030, with extended support to June 2035. This is the 64 bit Arm (AArch64) build running the Unbreakable Enterprise Kernel, for the Arm based virtual machine sizes powered by the Azure Cobalt 100 processor, which pair strong per core performance with lower cost than comparable x86 sizes.
Its root filesystem lives on an LVM logical volume inside a volume group rather than on a fixed partition, so the root volume can be grown onto a larger disk, data volumes added and storage reshaped on a running machine with standard LVM tools. It suits teams standardising on the newest Oracle Linux release that want to run web, application and container workloads on Arm with room to grow storage. This listing tracks the Oracle Linux 10 major release on Oracle's rolling repositories; the machine reports the current 10 point release it is patched to at procurement time.
The cloudimg image starts from Oracle's own Arm64 LVM image, is brought fully up to date at build time and again immediately before capture, and boots its newest kernel with superseded kernels removed. No credential is baked in: access is by the SSH key you choose at launch, password logins are off, the root password is locked, and SSH host keys, the machine id and network identity are regenerated per machine. Automatic updates apply every available update and never reboot on their own, the rpcbind port Oracle's image leaves open is closed, and defects that left Oracle's image degraded or inconsistent on Azure Arm sizes are fixed: the temporary disk warning no longer fails on sizes without a temporary disk, the clock runs in UTC, and the SELinux labels LVM writes are consistent on every clone. SELinux stays enforcing, firewalld stays active, the tested LVM growth procedure is in the paired guide, and 24/7 support is included.
