The latter is IIRC rebadged KubeVirt

OpenShift Virt is way more than Kubevirt.

It is, I was thinking more of the core of it. In the same way one might say modern Openshift is rebadged kubernetes, but I will admit it wasn't best word choice

The fifth largest (Morrisons) was also sold to PE with predictable results. https://en.wikipedia.org/wiki/Morrisons#CD&R_takeover

Was Morrisons ever any good?

Pretty damn good; not least because each store (aside from the smallest) has their own on-site butcher and fishmonger. Not to mention a decent deli.

> You simply take one of those redundant clusters and migrate one half of it over. For that half you are migrating, you are essentially operating without redundancy. If these are serious production workloads, the tradeoff is not as simple as you make it seem.

The way a cluster works is you have a giant pool of resources. Say, 33 - 50% larger than the workload. The workload is a dozen VMs. The cluster is 8 giant compute servers and two giant storage servers acting as one giant compute and storage unit. For redundancy you have extra clusters laying around with no workload, but they are added as failovers. Normally, if one server on a production cluster goes down, the other…

This is basically how HA works with VxRail. I buy more VxRail than I will actually host because if a node fails then the VMs can be moved - sometimes not always without downtime but no loss. If I run out of HA nodes or start running low on capacity, then Aria will start sending alerts.

I don’t know how anyone can afford these migrations especially for production on prem workloads without building literally duplicate sets of hardware clusters then manually migrate workloads.

It's a very scalable and almost fun task once you get into it.

Alternatives to VMware can run VMware VMs almost immediately, by translating the configuration and with only a few (or sometimes no) changes to the guest. Usually those changes are scriptable. I've done it a few times, moving between VMware and KVM of Windows guests pretty much just worked; the rest was optimisation, i.e. guest driver changes, etc.

Live migration is not realistic between different hypervisors, but a very short downtime per VM is realistic if the new hypervisor can adopt the old disk images directly, which some can. If you want, you can convert formats in the background while the VM is running on the new hypervisor. E.g. KVM and things built on KVM can do all these things.

So to each guest, it looks like a quick reboot with a quick hardware upgrade.

If that's coordinated properly, with a generic HA or Kubernetes setup, there's absolutely zero service downtime (if there are no serious mistakes), as it's just nodes within a cluster taken down one at a time while the others keep the services running, and state migrates among the nodes which are live.

Most of the things you'll change when migrating are the same for large numbers of VMs that are configured the same way except for their disk images, and easily minor things like MAC/IP. So after you've verified a small number, you can go right ahead and script the migrations for another thousand VMs, even doing them in parallel.

You don't need to migrate all VMs at the same time, and you shouldn't do that anyway. So the temporary hardware / cloud cost can be in the low single-digit percentage (for a few weeks to months at 40k VM scale, a few hours to days at 10 VM scale). You probably have some slack in there already, though, so might not need any additional hardware.

Their fish & meat counters are much better than the other supermarkets. Better selection and much fresher.

I never knew that! I'll try one out next time I'm passing.

Thanks for the recommendation, I'll pop by one over the coming weeks.

Mmh, you can get 3 el cheapo sandwiches for 1.99€, a 100g bag of chips for 0.99€ and a liter of water for 0.90€ or flavoured /coke for 1.99€ in Germany Considering a £ is more then a €, supposedly at last - it doesn't sound like a good deal to me

Can you give an example, as I'm not sure it's a fair comparison? https://www.tesco.com/shop/en-GB/products/262308005

honestly, they depend on the store you chose to go to. they always taste the same. and the last time i ate one of the sandwidches in the UK they tasted the same there too - but it's been a pretty long time, admittedly (like 20 years or so)

eg https://www.rewe.de/shop/p/ja-bacon-ei-sandwich-160g/7878218 cheap sandwidches (2€)

https://www.rewe.de/shop/p/lay-s-chips-red-paprika-150g/8940... chips 150g (99c)

https://www.rewe.de/shop/p/coca-cola-1-5l/6730574 cola, 1.25l (1.19€)

personally i'd skip the sandwiches in all cases - the wraps, baguettes or ready to eat salads are way better and cost the same. and i'd skip the chips too. i mean thats just pure calories. rather eat a great salad for 3€ instead of the el cheapo sandwidches and chips :)

Then I misunderstood, I thought you meant you could buy 3 sandwiches for €1.99, 67¢ each.

Tesco also have four choices for £1.50 each (€1.73), several 100-200g bags of crisps/tortilla chips for less than £1, and 2 litres of cola for 49p. This would be cheaper than the "Meal Deal".

Aldi-Nord often has packages with 3 in them for 2€, I was just unable to find them through the website, but I frequently see them as I often buy the 3€ salad right next to them - but they're not separately packaged if that was the misunderstanding

The FC multipathing was a learning experience and the manual workload placement requires good metrics on your workloads. The built-in ceph is decently configured and more performant than FC if you have 100GBS mellanox NICs and adequate quantity of ram. Veeam integration is serviceable but it's not as mature and polished as the integration available on vmware. Having tried azure local before (it seems magical but the…

And if you had to do it one a normal human setup of three hosts and 15 total VMs, no fiber, no san, no special nics or anything like that, just tied in to an ordinary Veeam with the ssd storage on an immutable Linux machine elsewhere?

I would choose promox or ovirt (oracle virtualiztion manager is pretty nice, I use it because the licence of the only oracle database of our institution requires it, that and a specialc cores pinning configuration, to avoid licensing every cores in all clusters, https://houseofbrick.com/wp-content/uploads/2015/03/Oracle-P... ) but it's oracle so we went with proxmox.
