    @florent Thanks for your reply! We have started to migrate thousands of VMs, so disk transfer speed is important for us.. We will also do our detailed tests soon with different threads setting and publish it here. I think threads=1 is a good and logical default, but not efficient. Others might complain if you set it to a higher value. Configuration option would be a real good solution.

    @poddingue My colleage managed to workaround the issue by re-installing the lab on other hardware, I think it is now Cisco UCS-servers. It was HP ProLiant-servers before. Maybe it was an issue with some of the NIC or firmware, im not really sure, but it works now.

    Hello I'm pulling stats for all VMs to understand CPU usage. We're a bit behind the curve in terms of XO versions, but these questions hopefully are still relevant. If using a granularity of days, the interval is set to 86400 (understandably) but the endTimestamp varies. Running this on June 9th @ ~1740 we get timestamps for both Mon Jun 8 01:00:00 AM BST 2026 and Tues Jun 9 01:00:00 AM BST 2026. Does this average across the day? Why is the timestamp 0100? Why would there be different timestamps between VMs (all are running) and does that mean that the figures are misaligned in the results? These are retrieved via curl and a bash script, a bit hacky, but for clarity the request is: ++ curl -X GET -s -H accept:application/json -b authenticationToken=[[REDACTED]] -o [[REDACTED]] 'https://[[REDACTED]]/rest/v0/vms/[[REDACTED]]/stats?granularity=days' Really keen to know if we can control the start and endtime, as well as provide a manual interval, as well as the aggregation strategy (min, max, average). Are any of these possible? Lastly, is cpuUsage the percentage as per the dashboard, but averaged over all CPUs? Thanks so much in advance. James

    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.

    The delta isn't computed over the network, but directly on the host itself

    @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
