    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.

    @Tristis-Oris yes it is likely you're using a newer kernel, we likely need to rebuild the agent using a newer version of the netlink crate.

    @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

    @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?

    @Danp Okay, you're a genius, I upgrade this morning after my backup. So that could explain my issue. the mentioned thread is exactly my issue, but I didn't find it when I was searching about my issue. Thanks for all !

    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

    @Danp So, that's the "best" way? Backup the meta-data with XOA, rebuild the OS drive - add the "new" server into XOA and restore the meta-data back to the new install? (I'm not doubting it is, just wanting to be sure we're understanding each other fully.) Seems straight-forward - but there's a ton of things I've done over the years that "seemed" pretty straight-forward that turned out to be anything but, and at least occasionally found I had no way back.

    @mmancina Hi you can try to call xe pif-scan host-uuid=<uuid of your host> , the NIC should appear after that.
