    @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).

    @firefly because the underlying hardware that the VM has registered has likely changed, maybe substantially. A sysprep has the Windows system go through and validate what it's hardware is, it removes hardware specific drivers namely, but it does other stuff too.

    When I reboot a host (a Dell 3680 workstation that we use for its graphics cards forwarded to VMs) it stops at the grub menu. We can hit enter to proceed and it works as usual until the next time we need to reboot.

    @olivierlambert said in Rust-based guest-tools... How are things going?: The thing is that it works very well and doesn't need fixes… I know, not usual right? It was so stable that we left it like that waiting for people coming for bugs and nothing happened… We'll cut a 1.0 in the next weeks/months. I have indeed seen the stability of it myself. But the lack of updates made me worry anyway. But I'm really looking forward to the promotion to 1.0 as well. Thanks!

    @bleader thanks for the tip. You see my knowledge in redhat based systems is almost non existant. Think I'm almost 99% debian and 1% ubuntu (and that not by choice) So I will take care of redeploying the script as soon as I upgrade, should be easily noticeable since monitoring will loose access and yell at me.

    @nikade said in Every virtual machine I restart doesn't boot.: @DustinB yeah im guessing the VDI isn't attached to the VM for some reason, based on the screenshot. Im also wondering if he ever rebooted the VM's after installing them with PXE Right, it's a likely answer... but even then I would've expected his PXE server to just restart the installation process all over again... assuming that the disk is attached to the VM etc and that PXE boot isn't disabled automatically like it is with an ISO after first boot. haha

    I know this is old but I had a similar issue. In the end I told dracut NOT to reassemble my raid array which allowed the system to boot perfectly after. I have no idea why it tries to assemble the same array two but on the second seems to be important

    @dinhngtu I think it just have been a bad migration or the Win 11 Template did other things to the windows 10 os. Since new test vm did not show the time issues, and a fresh migration of the vim with correct template selected did not have the issues either. I dont know but maybe there is a way to put detect the correct VM template or make note. I didnt think using the win 11 template would have caused issues since using the "wrong" template on vm creation does not have the same effect.

    Resolved. Patched the rest of the hosts. Restarted all the toolstacks for good measure. I can move the master role now, and deploy new VMs.

    Actually Alma Linux does have a variant for v2 CPUs so they can run 10.0. Just look for x86_64 v2 on the downloads page.

    Another thing that I noticed: despite enabling remote syslog (to graylog) for all XCP-ng hosts in the pool /var/log gets filled up to 100%. Adding remote syslog seem to not change usage of /var/log at all. Official XCP-ng documentation states otherwise here: https://docs.xcp-ng.org/installation/install-xcp-ng/#installation-on-usb-drives The linked part of the documentation indicates that configuring remote syslog can be a possible solution for /var/log space constraints which seems to be not the case. I feel like logging could use some investigation by Vates in general.
