XCP Release Timeline

For previous releases see: XCP_Release_History

Here is a rough guide to future releases.

XCP 1.5

Status: Permanent Beta
Last updated: 14th February 2012
Next status update due: Unknown

XCP 1.5 is version-compatible with XenServer 6.0. It's the first XCP release to be based on Xen 4.1. We have some internal work to do both on our build system and xapi before we can release XCP 1.5, but after we complete this work it will be much easier for us to release stable versions of XCP along with XenServer stable releases. This means that after these changes, there won't be any more long delays between XCP stable releases and XenServer releases.

Features that will likely make it into XCP 1.5:

  • Xen hypervisor 4.1
  • vSwitch is the default networking stack
  • Ubuntu guest support
  • Debian Squeeze guest support (32b/64bit)
  • Updated RHEL 6.0 support
  • Experimental SLES 10 SP4 support
  • Experimental Solaris guest support
  • Active-Passive NIC Bonding Support for vSwitch
  • Rolling Pool Upgrade improvements

XCP 1.6

Current status

  • Status: Beta 2 released
  • Last updated: 8 Oct 2012
  • Next status update due: End of October

Current known issues with Beta 2:

  1. Boot from CD splash screen shows "Citrix XenServer" (minor, in progress)
  2. Rolling pool upgrade from 1.5 doesn't allow VM migration from 1.5 host to 1.6 host (blocker, in progress)
  3. Performance issue with XenCenter connected (blocker, code complete)

Timeline for release

  • Beta 1: 1 Oct
  • Beta 2: 8 Oct (fixed upgrade functionality)
  • Test day: 9 Oct
  • Beta 3: TBA
  • Final release: 24 Oct TBA

See this e-mail thread for more info on the beta 3 and final release date.
