With local storage on each hosts, you won't be able to live migrate from 1 host to the other.

That's incorrect. The migrations will take significantly longer because the VDI will be migrated along with the VM's memory, but you can live migrate VMs between hosts even if the VDI are stored on local storage.

Sorry, I'm probably using a lazy definition of live migration. I know the VM and its memory can move.

Doesn't using non-shared storage ultimately cause the VM to be started on the other host?

@Pilow said in Recommended DELL Hardware ?:

@DustinB if he has CR, he could stop it, Failover, patch primary host, and eventually failback or reverse CR job

Yeah that would work, but would force some amount of downtime. Which most people say "we can't afford 5 seconds of downtime in a year" and then in the same breath say they have almost no budget.

@giejo said in Recommended DELL Hardware ?:

@Pilow thanks, don't want XO STOR for this use case, i just need one server in a room and the other in another.

Are you planning on performing Continuous Replication job from 1 host to the other? Just trying to gauge what your plan is for the split hosts to make sure you're not missing something.

With local storage on each hosts, you won't be able to live migrate from 1 host to the other. Singular Shared Storage (like a single Synology) creates a single point of failure, that you may want to avoid (but that needs clarification).

Where as two servers, each mirrors of each other with local everything, and just replicating VM's to each other every minute or so might be sufficient for your environment.

Of course you would still need to consider how you're going to patch the pool, since you won't be able to live migrate with shared nothing..

Pretty much anything would work, it would be recommended that you use current hardware. Current being a CPU not older than 5 years.

Ideally using shared storage, either using XCP-ng's VSAN offering or something like a NAS or SAN so you can migrate your VMs as needed.

Intel or AMD doesn't effect the equation, just don't use ancient hardware. If you need an HCL, I'd recommend you take a look at what Citrix has for their HCL and go off of that list, and having installed XCP-ng.

@DustinB

Yes dark mode light mode work just fine. Just themes do not stay applied. I tried from different computer and different browsers same results.

Win 11 pc with chrome and brave.
Ubuntu desktop - Brave and fresh install Firefox.

I even changed the domain name my XO-CE uses and same difference. It will stay working if i dont close the browser. The moment i close all tabs to the browser it defaults back to the default theme.

Open to other ideas.

I'm not surprised that it isn't "keeping" between different computers and to a lesser extent browsers.

Odds are it's a client-side cookie and nothing is saved to XO for your user account preference.

Interesting though.

@acebmxer said in ️ XO 6: dedicated thread for all your feedback!:

Also themes are still not staying applied. Same with XOA.

Do you mean the light, dark and auto mode?

I've not had any issue with either XOA or my XOCE installs keeping my selected mode.

@blueh2o the community is going to need some help from you.

Are you using XOA or XOCE?
If using XOCE, what version?
What version of XCP-ng is installed on your host
What backup medium are you using, NAS, cloud, windows server?

More details please

@acebmxer Yeah a ~15 minute VM migration isn't unacceptable either right? Like any DR plan can simply put that into effect.

But maybe someone else has some ideas.

The 21.46MiB is per second, which is approximately 1/5 of a GB per second.

So that really all kind of tracks...

@acebmxer From the looks of it, I would assume you have a 1GB network interface somewhere in the mix. A switch or something...

But I don't think you should expect to get a full 1GB wire speed in this case either...

@acebmxer So you're getting about 1/5 of the expected throughput... how are the CPU's behaving on XO?

Are they pegged?

@acebmxer That's a loaded question.

What type of connection do you have between the locations. From your edit - "(1gb dedicated Verizon fiber)"

What kind of networking components are in each pool and what type of NIC is the "Management" NIC on your pool master in each location?

200ish mbps is probably really good, but it could be horrible if you have 10gb fiber between the locations..

Is the underlying storage a NAS or some other shared storage that might have contention for IOPS?

I provided some feedback.

@olivierlambert said in XO 6 Official Release (for community):

Hi,

Have you read the release blog post? It contains many information, including a link to this:

https://feedback.vates.tech/?tags=xo-6&view=most-wanted

Feel free to upvote stuff in there to help sorting the priorities

Was in process of it, I plan to vote for it, just gotta swap computers.

I'm exicted that XO6 has dropped for the community edition and there are obviously things that are still pending.

I love that it's polished and cleaned up, however what I must be missing or isn't currently implemented is the ability to actually control the state of a VM. While I get that it's in the plan for next month's release that is a bit of big deal.

That said the screen space usage and the ability to flip back to V5 is easy enough to address this.

@rustylh We really need more information to even begin.

What version of XCP-ng are you using?
What hardware are you using to run XCP-ng?
What is the underlying storage where the VM resides on?
What OS is the VM running?
How are you taking snapshots, XO?
How old was the snapshot?
Were the guest utilities installed into the VM?
You do know snapshots are not backups, right?

@olivierlambert Fun fact -lah is short for lazy ass human

AI is coming...

@edsilber Yeah I'm not really sure, I also assumed that cron (and XO would use the cron pattern for months). Clearly it doesn't.

Using AT on the CLI of your host/pool should work (I imagine). But yeah having a "Run Now" function in XO would be killer.

@edsilber said in Schedule a single non repeating task:

I'm trying to schedule a snapshot for 8:00 AM later this week. I've got the task created but when I go to the schedules I only get repeating cron results, I can't get it down to a single event. How can I make the equivalent of an at versus a cron.

And another possibly dumb question, Cron syntax seems to use months 1 through 12 but the web GUI seems to generate 0-11

You would do this like this,

Granted this is technically every year on the same day. But you can just disable the job after the job ran.

@Biz365 Warm migrations from ESXi are ESXi license dependent on what you have/had with ESXi. Otherwise you can replicate the VM using the migration tool and then manually shutdown the VM on ESXi and then power it on XCP-ng.
