Can you do a
xe-toolstack-restartand see if it's better? (this won't interfere with the running VMs) -
@olivierlambert said in XCP-ng 8.3 public alpha
:xe-toolstack-restart
Done and it worked
now all the VMs are displayed.[21:24 xcp-ng-1 ~]# xe-toolstack-restart Executing xe-toolstack-restart done.
FYI vm154 memory is now reported.

Is it possible to take a snapshot with usb passthrough in version 8.3?
-
@mdavico Are you asking if it's possible to get one processed, even though a USB passthrough are currently enabled/active on the KVM, or?
I think you need to be a bit more precise. -
I'm jumped on XCP-ng 8.3 on my bleeding edge ODROID H3+. Are there any plan to support the build in sensors in the host system at some point, so it's possible to get CPU package temperature readouts? Right now, I've not been able to make any readouts from the host-machine, where I've tried a few sensor terminal tools
. -
@exetico I mean when you passthrough a usb, when you want to take a snapshot it gives the error VM_HAS_VUSBS(OpaqueRef:aedd32dc-6dec-4be1-aa5d-9dda799c01b2) and as in version 8.3 you can exclude certain vdi, possibly also a VUSB, that's what I mean
-
Has anyone tried installing 8.3 on a NUC12 yet? I'm about to buy a (maybe 2) NUC12 i5 (1240P) to replace my old tower servers at home. How does XCP-ng handle the hybrid architecture?
-
@ashceryth XCP-ng is based on Xen 4.13, so I'm quite sure it doesn't handle Intel Hybrid architecture. I'm not even sure there's ongoing efforts on this support in Xen Project Community.
Moreover, after a very quick check, I didn't see the trace of ARM big.LITTLE support in recent XEN.
I think this kind of features needs the profound analysis how exactly is to be mapped on hypervisor based platforms. And I think the response is not obvious at all.
-
Yes, it will simply explode if you have both cores types enabled at the same time. You will need to disable E or P cores (your choice).
The main reason is a really poor design choice from Intel, with those cores designed with similar functions doing different things. Nobody in the virt world want to deal with those.
-
Thanks, for your comments! That is basically what I was expecting.
-
@mdavico Saly, I also get a
VM_HAS_VUSBS(OpaqueRef:***/removed/**)error message in 8.3, if I have a ongoing passthrough.I'm not sure if it's the same thing with backups. If it is, that's problematic. One of my instances needs the USB Passthrough, but I need the rolling backup.
-
@exetico tested with virtualbox and it is possible to take a snapshot with VUSB
-
@ashceryth I installed the alpha version (8.3) on a Intel RNUC12WSKI70000 a few months ago without any issue. Worked like a charm, no custom mods needed. When the official 8.3 release is available I will reinstall from scratch just to make sure its still compatible/working.
Better to use the supported hardware of course but I like the sizes of the NUC'sEdit: I need to look into the hybrid part of the question. I'm not familiar with this at the moment so not sure what the implications are from that standpoint. Anyway, seems like the experts above already provided an answer on this one.

A new batch of updates for XCP-ng 8.3 alpha arrived.
It's been a while: one specific update I wanted to push together with everything that was ready gave us more trouble than expected, but now it's solved and so I pushed all the updates at once.
Main changes
xcp-ng-release*: updated repository definitions in/etc/yum.repos.d/xcpng.repo, to add more testing repositories (disabled by default. More about this here - look for "About the new testing repositories"). Warning: If you have any local changes to this file, it won't be overwritten. In this case, look for/etc/yum.repos.d/xcpng.repo.rpmnewafter applying the update, and move it overxcpng.repo. This won't change much for you as testers of XCP-ng 8.3, because we're still pushing the updates directly toxcp-ng-basewhen they are ready for your testing, but there might be the occasional experimental package in some other location - and the updated .repo file with make it easier to pull from there if needed.- AMD and Intel microcode updates (not the very latest yet, though)
sm(Storage Manager) ported to python 3 by XenServer, and we rebased our additional storage drivers on it- XAPI and related components
- HTTP to HTTPS redirection on the host's web page.
- lots of changes from upstream. Full changelog.
- IPv6 support added to
xhaandxsconsole. You'll need to wait for an updated installer in order to test this and the rest of IPv6 support for the management interface. memtest86+updated to 6.20 to support EFI hosts and more hardware. Will be available in the installer.xen: better hardware support (Ryzen...), security fixes, bug fixes...- Other updates synced from the preview release of XenServer 8.3.
zstd1.5.4 (1.5.5 soon)- removed corosync and dlm from installed systems. They were unneeded dependencies for XenServer's clustering support, which is proprietary and thus unsupported on XCP-ng. Let's trim dom0 down slightly.
We also continued our work on the installer and on automating the build of installer ISO images. We'll have new builds for you shortly.
How to update
From an installed XCP-ng 8.3 alpha, just run
yum update, and reboot. The usual update rules apply: master host first, etc. Check https://xcp-ng.org/docs/updates.html. I haven't tested it on this update, but XOA's Rolling Pool Update should work on this update.What to test
Depending on the time available, it goes from "just update and check things still work as expected" to "test everything you can think of", with an intermediate step of "test specific features which are important to you".

@stormi Thank you!
Are there any planned work related to hot backups of VM's, where a USB device are attached? It's currently not possible.
In the weekend I ended up moving a single container to a alpine image, so I could continue backing up my primary docker VM. But I was hoping to have rolling backup of the alpine VM, too
-
Update done on an Intel NUC11ATKC4 and a NUC8i5BEH, both are working fine
-
@exetico The topic of snapshots (and subsequently, backups) for VMs with USB passthrough is an identified one but there's no ETA at the moment.
-
@stormi Fair. Are there any public issue to follow? Maybe I didn't do my search that well? Thank you for the answer.

@exetico There are https://github.com/xcp-ng/xcp/issues/164 at XCP-ng level and https://github.com/xapi-project/xen-api/issues/4573 at upstream XAPI level.
