Cloudmin 5.7 released

Cloudmin version 5.7 is now available for download from our YUM and APT repositories. Existing users should see a message on the Cloudmin Information page after logging in, prompting to upgrade to the new release.

This update contains several new features, including :

  • A separate guaranteed memory limit can now be set for OpenVZ containers, at creation time and using the Resource Limits page. This allows over-committing of memory, by setting the guaranteed limit lower than the maximum. Over-committing can be enabled with a new option on the Edit OpenVZ Host page.
  • Added support for creating Xen and KVM disks with ext3 and ext4 filesystems.
  • Real systems can now be started by Cloudmin using a wake-on-LAN packet, if supported by the system’s BIOS.
  • The monitor for new and newly restarted KVM instances can now be accessed via a TCP port, which allows Cloudmin to perform some configuration changes without requiring a reboot.
  • Virtual disks and network interfaces can now be added to and removed from running KVM instances without a reboot, assuming they support PCI hot-plugging.
  • KVM virtual systems can now be paused and resumed, and live migrated to another host without requiring a shutdown.

It also fixes several minor bugs found since the last release. As always, please report any problems you find in this new version via the issue tracker.

Way to go, Jamie! Nice work!!

I take it we are now able to send ACPI shutdown signal to guests?

Yes, Cloudmin will attempt a shutdown using the KVM monitor (which I believe triggers an ACPI message) if the Unix shutdown command doesn’t work or isn’t available…
