By the way, if someone wants to have a look at how to build gpumon from its source RPM and prove me wrong about the impossibility to do it only with FOSS tools, I'll gladly revise my judgment
-
@stormi OK, just asked since the issue is about a year old and still unanswered by Citrix, wondering why it didn't show up in earlier xcp-ng releases. Perhaps they have only recently made some change to XAPI so it requires gpumon, and this change could be reverted (or better yet, fixed to handle the missing package gracefully, not hang the whole machine at boot time).

It's simpler: it's only with XCP-ng 8.1 that I have removed gpumon. That was a mistake so I had to put it back.
-
@stormi Thanks. Is this https://github.com/xenserver/gpumon - if yes, it doesn't look like something big, perhaps could be patched to remove dependency on proprietary nvidia stuff.
-
Yes, it's this. I've also create an issue for the XAPI project, that got good reception from the devs. All agree that XAPI should be able to start even if gpumon is not there.
-
Note that patching gpumon so that it doesn't depend on nVIDIA stuff probably just means making it a stub service that always answers the same regardless of the actual state of the GPUs.

Following yesterday's Xen security updates released by Citrix, here are test packages with security patches. As usual with security matters, they need to be tested quickly so that we can release them to everyone fast.
On XCP-ng 8.1
# on an up to date host yum clean all --enablerepo=xcp-ng-testing yum update xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools --enablerepo=xcp-ng-testingreboot (master first)
On XCP-ng 8.0
This batch of updates contains not only security fixes but also bug fixes that I had queued for the next patch train.
# on an up to date host yum clean all --enablerepo=xcp-ng-testing yum update bugtool-conn-tests qlogic-netxtreme2 qlogic-netxtreme2-4.19.0+1-modules sm sm-rawhba xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools xenserver-status-report --enablerepo=xcp-ng-testingreboot (master first)
On XCP-ng 7.6
XCP-ng 7.6 is not supported anymore, so there are no updates available for it.
-
Hi users!
Today's the last day to install the update candidate and give feedback. If you have any test host, please install and reboot. That's it and it's useful to us.

Update released: April 2020 XCP-ng Security Updates
-
Intel CPUs "CROSSTalk" vulnerability.
Following the disclosure of the CROSSTalk CPU vulnerabilities and the release of updated microcode by Intel, here are update candidates for XCP-ng 8.0 and 8.1. Prompt feedback by all available testers is wanted.
Details and discussion in the dedicated thread.
-
-
I haven't had many tests from the community for the previous updates.
I'm still trying to convince myself that I can count on the community to test updates before they are released to everyone, in addition to our internal testing.
So, here are new update candidates, related to the latest Xen security advisories, for XCP-ng 8.0 and 8.1.
Install them with
yum update xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools --enablerepo=xcp-ng-testingand reboot.
Your host is just supposed to keep working normally as before.
Thanks in advance.

Did the update and a reboot just minutes ago.

Update published. Thanks for testing!

Hi everyone.
An update candidate is available for netdata packages in XCP-ng 8.0 and 8.1. Feedback about it is welcome.
They fix two issues:
- a buffer overflow in JSON parsing, that could pose a security threat
- netdata logs being flooded due to a bug in the computation of the last vcpu number
To install the update candidate on XCP-ng 8.0 or 8.1:
yum update "netdata*" --enablerepo=xcp-ng-testingThis will update the
netdataandnetdata-uiRPMs if they are installed on the host.You can also install them if not already present with:
yum install netdata-ui --enablerepo=xcp-ng-testingNote that installing netdata-ui automatically opens port 19999.

Doe the netdata update not actually fix the missing network interfaces or virtual drives?
-
@Biggen I am not aware of this problem. Mine (updated) displays the server's 6 physical eth interfaces and 3 more xapi0 ~ xapi2 and 9 physical drives sda to sdi. I still not have multipath configured in the servers.
