    @poddingue Thanks for looking into this! I checked the bulk "Reconnect to all hosts" action as well, and you're right — it doesn't work either. It only works if I select a single SR, open its page, and use the "Reconnect to all hosts" action from there.

    To add some context on our own use case: our standard xo-server logs already go to syslog through [logs.transport.syslog] and on to our central log server, and that works fine. The problem is that a lot of the useful information only exists in the audit log: who did what, which API calls were made, from which IP. Right now that data stays inside XO and we can't correlate it with the rest of our infrastructure. For us it is also a compliance issue. We are subject to PCI-DSS, and Requirement 10 expects administrative actions to be logged, promptly sent to a central log server and reviewed, ideally with automated tools. XO is where our virtualization admin actions happen, so its audit log is exactly the data an auditor wants to see in the SIEM. Having the audit records go through the existing pipeline, as this PR does, would make life much easier: no polling script, no long-lived admin token, and everything ends up in our SIEM in real time. @Team-XO-Backend, a review would be much appreciated.

    For anyone else who steps through this, I've also installed the latest xen-guest-agent with the below process. Repeat for each host in the environment, 1 at a time from your Helper VM. ### ssh into your helper ### oc debug node/fedora-cmp-1/2/3 chroot /host cd /var/tmp curl -LO https://gitlab.com/xen-project/xen-guest-agent/-/jobs/6041686376/artifacts/raw/RPMS/x86_64/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm sudo rpm-ostree install /var/tmp/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm mkdir /var/tmp/xga && cd /var/tmp/xga rpm2cpio ../xen-guest-agent-0.4.0-0.fc37.x86_64.rpm | cpio -idmv ### From your helper... DRAIN YOUR WORKERS ### oc adm drain fedora-cmp-1/2/3 --ignore-daemonsets --delete-emptydir-data ### log back into fedora-cmp-1/2/3... ### sudo systemctl reboot ### from helper ### oc adm uncordon fedora-cmp-1/2/3 ### login to fedora-cmp-1/2/3 ### chroot /host sudo systemctl enable --now xen-guest-agent And then from XO this is what your VMs will look like.

    No. The parent folder. XO will search for the folder xo-vm-backups directly edit: if your share was previously <NFS_IP>:/myshare, then you should use this very same one, and NOT <NFS_IP>:/myshare/xo-vm-backups

    There's 2 reasons: XAPI doesn't tell us if the transfer is complete or just cut. We just stop to receive chunks, and after a bit, we decide that's it, there's no more data to send (that's the normal behavior even when it works!) XVAs are hard to validate, depending on various factors. We do a VHD validation (so for delta backup) but XVAs are another thing

    On the remote side, right? It won't be "dedup" if it's your question (for now at least). We are thinking on a smart way to dedup it efficiently It's not trivial because we don't have a lot of control on the host itself, but we might find solutions.

    @nraynaud well i just used the datastore browser to download the vmdk. i did the same thing with some other (smaller) VMs without any problems. All of this from the same ESXi host. Thanks for looking into it though, i will try the export VM way next but have to find the right time for a shutdown ...

    That's correct @mauzilla We use a VHD chain on destination so it's equivalent to get "snapshots" of a VM So it's delta everywhere with the same full parent for the same original VM.

    @slynch OK, that's very good news then! Debian was still having issues where any configuration applied via cloud-init would just be added to the existing default DHCP config, unless you took care to build the VM without the default interfaces config beforehand.

    @olivierlambert said in PCI Passthru Error not working on 8.2 but was 8.1: Hi! IOMMU should be enable in the BIOS. Double check that Also please share your grub config to see if it's correctly written. After playing with it more, the issue appears to be passing multiple devices of the same type. In this case RADEON WX7100. If I take it down to one card it works as expected. If I add more than 1, pick any quantity, then I run into the issue. The issue goes away once I reboot the host, and then I can assign a card, but the second the VM reboots the error comes back

    This can happen from time to time on master (despite we do every "broken" code in dedicated branches), sometimes you can have a surprise. That's why it's important, before anything, to get the latest commit and rebuild, to see if the issue persist. If it's the case, then reporting the problem will be helpful

    The best way would be to use XO Proxies as "Reverse HTTP proxies" (or any reverse proxy in each DC) and then tell XO to connect to those proxies. This way, each DC will have only one entry point exposed to the outside, and you could manage that with your central XO. This is a subject we planned to work in the next months. If you have a support subscription, please open a ticket so we can do initial test inside your infrastructure

    @magtech If you want to do a XOA quick deploy, you need a working internet connecting and outbound port tcp/8888 must be open to the internet. New install of XCP-ng, can't complete Quick Deploy might help?
