    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).

    @florent said in vmware vm migration: @acebmxer yes after the first migration, XO knwo that the migration is incomplete and that you may want to finish it later. But if you start this VM direvtly , it will write some data, thus it won't be in sync anymore with the Vmware snapshot. Then XO won't be able to resume You can start a copy of the VM ( XO will handle it for you ) and delete the copy when you're done My advice is to migrate this VM to the right SR and then do the resume. But keep in mind that the V2V tool is intended to target only one SR, so migrate all they disk to the same SR, and select the right one when resuming the V2V. You can change the network after My previous migration was successful with no issues. Previously test vm was fresh install so no vmtools installed. But I did shut the vm down myself prior to starting the migration. VM boots no issues no prompts. This time I decided to follow the steps listed in the documentation as i have been following the changes and updates for the v2v migration. Following the steps as mention XO presented me with that prompt which was not mention in the documentation. As i was typing the post to gather my information it was then i noticed i did not select the proper destination SR and the appropriate nic/vlan for networking. So I noted that in the post. With the assumption i could correct that on the final migration. With that said the I guess the documentation should state - Start vm to test if boots, etc.. When prompted choose "Start a copy". When done shutdown vm and remove.

    @whyberg Nope... that feature is part of the CPU. But is that the actual problem? Maybe... As that machine is too old to do any real work, it's a fine toy. There are better faster cheap test machines available.

    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.

    Hi Forza, Have you finished migrating the workloads? If you are still looking for an easy migration solution, you can try Vinchin Backup & Recovery. It will replace the driver during migration intelligently.

    @olivierlambert Thank you for the reply. There was a thread on here about the iso not being mounted properly and I commented about having power off the vm and back and it will load the iso. This is specifically true with the 0.4.0 for linux. Image pulled from the XO Hub will not mount the ios if the vm is powered on. There is Yellow Explanation mark next to it. Power off vm and power on vm iso is ok. Reboot vm does not let the ios to work.

    @Pilow Yes, we monitor observability metrics for guest OSes via other means but being able to see this info via the Xen Orchestra web UI along with the other metrics in the Stats tab definitely has is benefits, especially when performing initial troublehshooting or when dealing with groups in our org that only have access to the XO interface and not the other metrics dashboards. Don't get me wrong, I definitely appreciate all of the work that you are all doing to get these tools working and can't wait to start using them in production. I just need to make sure that they work as expected.

    @zpvS9 said in Error installing windows PV drivers 9.0.9137: I have this error too installing the new PV driver, after uninstalling Citrix driver, reboot, execute XenClean, reboot again, it said that an unsupported device is still present. I must uninstall the device by showing hidden device in Device manager and the Windows PV driver now install. So adding this step in XenClean would be appreciated. encountered the same problem with hidden base system that i needed manually uninstall to get the tools to work.
