    @redakula said in Coral TPU PCI Passthrough: Frigate.nvr which is one of the popular uses for the Coral do not recommend it for new installs either. Frigate updated their recommendations because of the Google decision to sunset the device and because there are alternative options available to frigate for image inferencing. The coral is still supported though, and frigate is not the only use case or platform that can benefit from an accelerator. At the end of the day if you've already got the hardware, and it's efficient enough to run, then not using it is a waste or resources that could be allocated to other VMs.

    It's not meant to be used like that. If you are behind a NAT, the right approach is to have your XOA behind the NAT and inside the same network than the hosts. That's because hosts will always use and return their internal IPs to connect to some resources (stats, consoles etc.). XOA deals with that easily as being the "main control point" for all hosts behind your NAT (or a XO proxy if you prefer).

    @yeopil21 you can target vsphere it should work The issue here is that XO fail to link one of your datastore to the datacenter is it XO from source or a XOA ? you should have in your server logs something like can't find datacenter for datastore with the datacenters and the datastore name as detected by XO are you using an admin account on vsphere or is it a limited one ?

    @comdirect Use this command: (replace sda in the command below with the relevant device) cat /sys/block/sda/queue/scheduler The active scheduler will be enclosed in brackets. e.g. noop deadline [cfq] For multiple drives use: grep "" /sys/block/*/queue/scheduler

    @Tristis-Oris yes it is likely you're using a newer kernel, we likely need to rebuild the agent using a newer version of the netlink crate.

    @bloodyskullz If you still see the old ISO SR, the easiest way to migrate is simply by creating a new one and migrate the ISOs through XO to the new one. In regards to deletion of the old SR you need to check if it really is mapped to another drive or if the mapping was not working and it filled / if so, you might not be able to delete it

    @bleader said in update via yum or via xoa?: yes you're basically doing an RPU manually. But it is indeed odd that the process is stuck at 0%, it should be fairly fast to do the install patches, no errors in the logs? i've another install all patches and install all. Now i'll use rpm update and see if speed is the same or not

    Pool Tasks Don't Complete? Major Issues...

    @Danp Yes to both. I've probably restarted the toolstack at least a dozen times, mostly to clear hung tasks. I did notice some weird issues with a secondary SR being disconnected on xcp02, (one of 10 hosts, 9 after I ejected and forgot xcp01), but there's no disks on it. It wasn't being used for anything at all (yet), and it's fine on all the rest. That does lead me to think maybe it was a power bump that rebooted a switch or something though. Maybe it caused some kind of hangup with xcp01 and xcp02, and since xcp01 was the pool master, it cascaded to the other issues I've seen? Could that cause the VM's that were originally running on xcp02 to die and not be able to be recovered easily?

    No, from the XCP-ng point of view, the VM is still running without any interruption.

    @NerdsOrder66 Ah, good question... My most recent environment included a Windows Server with 100+ RDP users. There wasn't anything special for optimization there aside from giving it a bunch of RAM/CPU resources, but YMMV.

    @olivierlambert No, the only thing I get with xl dmesg on the host, for some time back, are random brief reports of individual CPUs running above temperature threshold and then being clocked down, and then resolving. Nothing else.

    Indeed, but it's a bit old, and I would say for many reasons HVM with PV drivers is still the way to go for classical server virtualization mode

    Interpreting vulnerability scanners is a hard task. They are often screaming for "common cases", but remember XCP-ng is an appliance, so there are many cases where things do not apply. Happy to help you further via our pro support to answer in details your concerns
