@poddingue said: Thanks for posting the fix. The same thing came up in an older thread, https://xcp-ng.org/forum/topic/9957, where disabling IPv6 also made xoa check go green. @HamiltonWDS explained a likely reason in https://xcp-ng.org/forum/post/87831: Node tries the addresses with a short timeout and can end up on the IPv6 one. Your curl -6 test helps a lot here, because it shows IPv6 doesn't connect at all on that network, so it's more than a slow path. Turning it off in XOA seems reasonable if you don't use IPv6 there; if you do, I'd guess the router side is where it really needs fixing, though I could be wrong (still haven't migrated to IPv6 myself ). Curious whether it sorts out the Cloud Backup too. XOA is using our management network where ipv6 is not needed and not enabled. Looks like our cloud backup finally ran for the first time in while too.[image: cloudbackup.jpg]

I didn't know, so I went and looked at the code. XO prunes that list in a cleanup step: backup runs are kept for 31 days, and other tasks are kept by count, the newest 1000 (https://github.com/vatesfr/xen-orchestra/blob/b59c8f3d20954aa1d72e92c1e8f2db635d74fcba/@xen-orchestra/mixins/Tasks.mjs#L119-L127). You can change both with tasks.gc.keep and tasks.gc.backupKeepDuration in the xo-server config. As far as I can tell the cleanup runs when xo-server starts, not on a timer, so a long-running XO can collect quite a few before the next restart. My guess for the Cloud Backup entries @acebmxer still sees after 30 days is that they're kept by count rather than by age.

I tried it on a lab host (XCP-ng 8.3, xapi 26.1.16): calling VM.pool_migrate on a halted VM gives me your error, VM_BAD_POWER_STATE with running, halted, so the two values are the state XAPI wanted and the one it found. On the XO side, a migration inside the same pool with no SR or network mapping goes straight to VM.pool_migrate without checking the power state first: https://github.com/vatesfr/xen-orchestra/blob/b59c8f3d20954aa1d72e92c1e8f2db635d74fcba/packages/xo-server/src/xapi/index.mjs#L942-L981. So a stopped VM in that batch would give this, which fits what you remember. I haven't tried the batch migrate from the UI itself though, so I don't know if the UI is supposed to filter halted VMs out before that. It's a good concrete example for the feedback post anyway, XO could just say "this VM is halted" instead of passing XAPI's raw code through.

@john.c Indeed, John, and I almost forgot that the backup network on each host was actually on a separate, isolated NIC, and not at all on the VLAN.

@fohdeesha Hi all, I apologize that it's taken a while to get all the issues sorted, fixed and properly verified. I have pushed the corrected version up to my GitHub, and everything seems to be working much better (thanks to the efforts of everyone here)! A big shout out to all of you, as this is exactly how open source is supposed to work! Let me know if there are any other issues that arrise - and Happy Day to one and All!

@coolsport00 Sorry about the VMW need for the Cisco product. Sounds like you have a number of constraints, finances being I'm sure one of them! At least you have time on your hands and the means to experiment. You may, als, end up with a number of different platforms to meet your needs. We ran both Sun Microsystems and Red Hat Linux and Microsoft Windows servers, each taking on specific duties. It's far from ideal and probably not very cost-effective, but you do what you have to to get stuff to work.

@irtaza9 Hello, could you share the content of your logs during the SR creation with us to investigate on our side ? You can produce a tar of logs with https://docs.xcp-ng.org/troubleshooting/log-files/#produce-a-status-report .

@poddingue Hey, it's just fun building stuff, even if it ends up in the bit-bucket (as unfotunately that's the destiny of all things anyway). Happy Day

If you are running XOA, not XO from sources, then we could take a look remotely using the support tunnel. Otherwise, make sure that you have patched and rebooted each pool member.

Hi, Thanks for your answers For the second problem, after deletion, it is impossible to have the connection to the xo-server despite the refresh of the XOCE page. In a new firefox tab = same problem I closed and then opened Firefox and xo-server connection = OK Best regards

@olivierlambert - Just updating. The issue is still present in the version: 6.7.1. I doubt any fix was made. May be not many people are deploying windows 11 with vTPM through templates. Otherwise this issue should have been reported by others.

Just wanting to express my thanks for the script which seemed to do the trick in resolving this issue for us, once we were able to get the HVM migrations completed to enable the move to 8.3. We understand it is not a long term fix for the underlying issue, but appreciate all we have been given. Thanks.

No problem, this is always good to have feedback and cases showing an error and the explanation

What kind of storage are you using? Is it a 4K block native storage? You should be able to see if you can create a virtual disk easily with xe vdi-create name-label=test virtual-size=1G sr-uuid=356475ac-…

Hi! No, but check XO logs/output to see what's going on

@poddingue Oh yes (dumb me). Very good, we'll see if they respond (as now there's two @ refferences). Happy Day

Thanks a lot @msupport ! @all-ki could you add this to our IPMI doc to be published ?

Hi @dvdwx, RBAC is available only at the REST API level, not through the XO6 UI. UI compatibility with RBAC is currently under development. For the topology, this is something that has been here for a long time, so I may be wrong since I don't have the full history. However, if I look at the code, creating the topology selector requires knowing how many CPUs are available in the pool. Since a self-service user doesn't have visibility into the pool, they can't access this kind of information.
