... ah forget it, I see, CentOS is using the old versions since long time ...
Yeah the chances that we'd change the version of such a low level package just for added functionality are very low.
zfs is not part of the default installation, so you need to install it manually using
yum from our repositories. Documentation on the wiki has not been updated yet for 8.0: https://github.com/xcp-ng/xcp/wiki/ZFS-on-XCP-ng
Now the zfs packages are directly in our main repositories, no need to add extra
--enablerepo options. Just
yum install zfs.
I've just built an updated zfs package (new major version 0.8.0 instead of the 0.7.3 that was initially available in the repos for the beta) in the hope that it solves some of the issues we had with previous versions (such as VDI export or the need to patch some packages to remove the use of
O_DIRECT). I'm just waiting for the main mirror to sync to test that it installs fine.
No one raised their hands, and yet an update candidate for 7.5 is available with the fixes backported from 7.6.
Install it with
yum update --enablerepo='xcp-ng-updates_testing' microcode_ctl xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools
We've tested it locally, works fine for us.
Good morning, afternoon, evening or night to everybody.
The beta release of XCP-ng 8.0 is available right now .
side-channelattacks on legacy Intel CPUs. See Citrix's Hardware Compatibility List. Note: in 7.6 we've started providing alternate drivers for some hardware. That's something we intend to keep doing, so that we can extend the compatibility list whenever possible. See https://github.com/xcp-ng/xcp/wiki/Kernel-modules-policy.
emu-manager, rewritten in C. Test live migrations extensively!
yumnow pulls from them: https://github.com/xcp-ng/xcp/wiki/Mirrors
xfssupport for local SR are still considered experimental, although no one reported any issue about it. You still need to install an additional package for it to work:
yum install sm-additional-drivers.
zfspackages have been updated to 0.7.13. The known limitations (no VDI export...) remain for now.
qemu-dpfor Ceph support, due to stalled issue in 7.6 (patches need to be updated). However the newer kernel brings better support for Ceph and there's some documentation in the wiki: https://github.com/xcp-ng/xcp/wiki/Ceph-on-XCP-ng-7.5-or-later.
extras_testingdisappear and there's now simply:
andtesting`. Extra packages are now in the same repos as the main packages, for simpler installation and upgrades.
At this stage you should be aware that our main documentation is in our wiki and you should also know that you can all take part in completing it. Since the previous release, it has improved a lot but there's still a lot to improve.
As usual, there should be two different upgrade methods: classical upgrade via installation ISO or upgrade using
yum-style update is not ready yet. Since this is a major release, Citrix does not support updating using an update ISO, and the consequence for us is that the RPMs have not been carefully crafted for clean update. So it's all on us, and we plan to have this ready for the RC (release candidate).
Before upgrading, remember that it is a pre-release, so the risks are higher than with a final release. But if you can take the risk, please do and tell us how it went and what method you used! However, we've been testing it internally with success and xcp-ng.org already runs on XCP-ng 8.0 (which includes this forum, the main repository and the mirror redirector) !
Although not updated yet, the Upgrade Howto remains mostly valid (except the part about
yum-style upgrade, as I said above).
It's a good habit to check your downloaded ISO against the SHA256 sum and for better security also check the signature of those sums. Although our mirror redirector does try to detect file changes on mirrors, it's shoud always be envisioned that a mirror (or in the worst case our source mirror) gets hacked and managed to provide both fake ISOs and SHA256 sums. But they can't fake the signature.
yum update regularly. We'll fix bugs that are detected regularly until the release candidate. Subscribe to this thread (and make sure to activate mail notifications in the forum parameters if you need them): we'll announce every update to the beta here.

A community effort to list things to be tested has been started at https://github.com/xcp-ng/xcp/wiki/Test-XCP
Latest XCP-ng security bulletin, dedicated to the recently discovered MDS attacks on Intel CPUs. Update available but also requires extra steps for full mitigation.
Raise your hands if you're still using XCP-ng 7.5 and badly need an update. As you know, we try to support the N-1 release of XCP-ng on a best-effort basis, but backporting the fixes may not be trivial, and 7.5 is very close from end of support from us with the upcoming release of XCP-ng 8.0.
Was a long write but should be a short read
@Ultra2D For this update, I think you could try with a slave first, since it's only an update of xen (and microcode_ctl), so I don't expect incompatibilities in pool management. But I wouldn't guarantee that cross-host operations such as migrations would work fine.
