Updates announcements and testing
The update for 7.6 has been made available as a regular update, as
xcp-emu-manager-0.0.6-2.x86_64.rpm. It should prevent most migration crashes, but can still get stuck when the VM is heavily loaded. Instead of failing directly, it will now try to wait for a low enough activity to resume the process. We're still working on it to bring a better, complete solution.
- target: XCP-ng 7.5 and XCP-ng 7.6
- reasons for the update: security update

- 7.5: same packages in version 4.7.5-5.7.1.xcp
- description of the changes:
- Security fixes from the Xen project
yum install --enablerepo='xcp-ng-updates_testing' xen-dom0-libs xen-hypervisor xen-tools xen-dom0-tools xen-libsor if you don't mind installing other update candidates at the same time:
yum update --enablerepo='xcp-ng-updates_testing'
- testing tips: basic functions of the hypervisor
- reboot: yes
An update to XCP-ng 7.6 has been pushed:
xcp-emu-manager-0.0.9-1, that fixes all known migration issues (well, except this bug from XenServer: https://github.com/xcp-ng/xcp/issues/111). Update for XCP-ng 7.5 is being prepared.
New update candidate for XCP-ng 7.6. It adds support for NFS 4.1, that has been contributed by a member of the community and already merged upstream in the XAPI project!
yum update sm sm-rawhba --enablerepo='xcp-ng-updates_testing'
yum downgrade sm sm-rawhba
Thanks in advance for your feeback!
I feel alone in this thread

@stormi I am watching you.
We are the watchmens
I'm here. Alive n' kickin'
So did anyone install the update candidate for
sm, check that they see no obvious regression and ideally test NFS 4.1 support?

I have an netapp storage. it support nfs 4.1. how can I add a nfs sr with nfs 4.1? I want test it.
@stormi I did not test it (yet) .. currently copying loads of vm data around at work... but if all goes well I have a free storage next week that will become our new nfs4.1 server for work ... stay tuned
@rizaemet-0 here is a XCP-ng Center with NFS 4.1 support: https://github.com/xcp-ng/xenadmin/releases/tag/v126.96.36.199
Just add your NFS SR via the normal assistant, the NFS 4.1 option is right there.

I create a nfs sr with nfs 4.1 with xcp-ng center v188.8.131.52. success.
live storage migrate a vm to this sr. success.
live vm migrate to another host. success.
backup vm with xo. success.
I tested copy-paste file in itself and nfs4, nfs4.1, fc between each other. nfs 4.1 speed is like nfs4 speed for my environment.
heavy i/o for 24 hours. no any performance or another issue.
Do you have better perfs than 4.0 by the way?

@olivierlambert Similar performance for my environment. I did not any specific test. Just copy-paste files.
By the way, is multipath connection (or pnfs) possible xcp-ng between storage with nfs4.1?
It should be possible if you SR is supporting pNFS (because IIRC, it's included in 4.1 protocol).
However, pNFS doesn't remove the usual SPOF (metadata NFS server)
pNFS may not be available in XCP-NG's kernel. I see option
CONFIG_NFSD_PNFSunset where as most of the distros have
@r1 I think that config option is to enable pNFS server support, not the client. I'm pretty sure this being disabled just means that XCP-ng can't be used as a pNFS server (though a VM running on it certainly could).
