    @stormi I really appreciate the continued help. I'm not sure it works. On my single-host pool master—the one I want to join into my half-upgraded pool—I run the command: xe host-emergency-disable-tls-verification It returns with no errors. If I do xe host-param-list and look through the parameters for my host, I see: tls-verification-enabled ( RO): false This is the only thing I see documented that can turn off TLS verification. If some other command like pool-uninstall-ca-certificate would have the effect of disabling TLS verification, I can't see that documented anywhere. In fact, even though xe pool-uninstall-ca-certificate appears to be a valid command that my xe binary knows about, I can't find that particular command documented at all. Even after the emergency-disable-tls-verification, if I attempt to join that host to the half-upgraded pool (using xe pool-join...) I get: Error code: POOL_JOINING_HOST_TLS_VERIFICATION_MISMATCH It seems like even though the host has TLS verification off, the fact that its pool has verification enabled is blocking the action.

    Hi, Latest XOA, with fully patched XCP 8.3 here. I'm fiddling around again with NBD+CBT in backup jobs (was avoiding CBT for a time, to reliably control my backups and avoid unnecessary KEY points) in the context of THICK SRs to spare some space. I know that CBT is reset when migrating from one SR to another. But here is what I encounter : VM has no CBT enabled on its VDIs, it is on a SHARED SR in a pool of 3 hosts backup option changed for NBD+CBT, was only NBD before CBT is enabled on the next run by the backup job, I get a delta (was expecting a FULL ?) next run, delta, as expected i migrate this VM on another HOST, without changing its SR CBT is immediatly disabled ? why ?? next run of backup it tries a delta, but "fall back to a full" (normal as CBT has been disabled...), and do a KEY point on the remote next run is a delta as expected does this mean if I do a rolling pool update or host maintenance that will move the all VMs around, all CBT will be disabled and I should expect a FALL BACK TO FULL on all my NBD+CBT enabled backup jobs ??! why disabling CBT on a change of HOST and no move of SR ?

    We patched some part of SMAPIv1 to "make it work" (our patches were even merged) but VHD export is another (more) complicated story. That's why we are working on SMAPIv3 now instead wasting resources on the "legacy" storage stack

    XOA: VMs' consoles don't work ("Unknown key pressed, Unknown key released")

    @Danp said in XOA: VMs' consoles don't work ("Unknown key pressed, Unknown key released"): What version of XS / XCP? Are you fully patched? XOA is on XCP-ng 7.6 which I installed 3 weeks ago and then updated with yum, so still up-to-date, I believe (not trying to update at the moment as I'm in a process of migrating and don't want any reloads/restarts of XCP-ng. VMs were on XenServer 6.2 updated with all patches available. Additional info: one of the Linux VMs which I tried to use XOA's console with, was already on XCP-ng 7.6 (the same as XOA) and here behaviour was different (but bad anyway): hitting Enter was giving newlines, AFAIR, but the console wasn't reacting on other keys. This may help -- https://xen-orchestra.com/blog/xenserver-consoles/ Thanks. Though I'm not sure which keyboard layout the blog mentions... Of the browser (client)? Of the host with XOA? Of the host with the VM observed on the XOA's "console"?

    What you found is a pretty old and outdated thread, and conclusion is: It's not limited - and there's no real difference between 1 and 10GE. In case it's limited to protect mgmt-int, it would scale with 10GE, but in fact it doesn't.

    Use a single partition because this is a nice way to let cloud init grow the system disk if needed. I made a guide a while ago about doing this on a Debian, it's exactly the same principle: https://xen-orchestra.com/blog/debian-cloud-template-for-xenserver/

    I ran into something VERY similar with XCP-ng and\or XOA a while back - ended up with close to 200 new "clients" showing up on my Meraki gear. They weren't even "connected" long enough to register as IP clients, only MAC clients (ARP, possibly). I didn't think much about it at the time, as both the MAC addresses and hardware information didn't seem to be tied to any actual device by some manufacturer. I may be able to pull those out from my client history... EDIT: Here is a small section of that list: [image: 1556589256050-fc439a0c96cb13a0b2b11b3bd80ff3be.png]

    To get assistance on XOA, since you have support, it's better to go with our support ticket system. This way, you can be sure to have an answer with direct developer access in a guaranteed amount of time. Please open a ticket here: https://support.vates.fr/#/tickets XOA isn't dealing on what's inside on the VM: it's an hypervisor-level agentless backup solution. As soon you create the ticket, we'll take a more in-depth look about details (what kind of backup are you using? Delta or full etc.) and also if there anything special we could do at our level.

    I don't know what's the /xen path? Install via this docker isn't the official/documented way, so it's hard to assist. Please try to build it according the doc and double check if reverse work as documented too. Otherwise, it's an issue of the Docker you use with our doc, so you'll better time to create an issue on the 3rd party "installer".

    It depends where you decided to install it (basically where you cloned to repo). Also remove the redis database if it's only used for XO.

    If you didn't, I strongly suggest that you watch the live YT webinar I did on XO backups. IIRC, there is a part talking about smart backup. https://www.youtube.com/watch?v=FfUqIwT8KzI

    You have a problem on your XCP-ng, this is not related to a XO issue. It's stuck doing a snapshot, which is really a basic operation that shouldn't fail at all. Double check your SMlog on the host.

    It looks like I can remove the remotes and set them up again, and configure the backup jobs to address the new share. That's okay, there are not too many.

    You need one XOA, connected to both pools. It will stream the VM content (delta) from the source to the destination. You don't need any directly link between your SR in both DCs. You DCs can be isolated with just one XOA connected to both, and it will work.
