// Xen Orchestra
It's out! Latest CR version of XenServer is available. So what's new there?
If you don't have a licensed version of XenServer, upgrading/udpating to this version will remove those features:
- Xen storage motion
- Dynamic Memory Control
- Basic GPU Passthrough
- Pool size limited to 3 hosts max
- and more, details here
If you need a license, you can contact us (live chat of our website), as we are a Citrix partner and reseller. We'll help you about licensing.
If you have an Enterprise license for XenServer, you'll have:
- Efficient multicast support via IGMP snooping
- Support for NVIDIA Pascal graphics cards
- Nested virtualization for Bromium Secure Platform
- Changed Block Tracking
We reviewed the CBT features: in short, the only advantage vs current Delta backup, is that you can remove the reference snapshot (and leave only the metadata). But it doesn't solve the main problem about block based storage that aren't thin-provisioned anyway. Because you still need to create the snapshot at the first place.
However, there is interesting features hunder the hood of CBT:
nbd protocol, which will be probably useful for Xen Orchestra in the future, to have more flexible fetch of VM content.
Right now, it doesn't change anything: Xen Orchestra is fully compatible with XenServer 7.3!
Should I upgrade?
- If you are on 7.1 LTS, and happy with it, stay.
- If you are on 7.2 without license, you'll lose some features.
- If those are too important for you, you can stay in 7.2
- Or buy a license
