Re: Running OpenBSD on Hypervisor
Hi, I have not experienced any problems virtualizing OpenBSD with KVM, Xen, HyperV, VMware. I have done various performance tests over the years and found KVM to be the best performing, most stable platform for our environment. Those non-scientific tests simulated some of our typical workloads - web platforms (php,js,python), databases, filesystem, running various stuff in a single VM up to 8 different VMs... they were performed on entry level server hardware though: maximum 2 CPU sockets, max 128GB RAM with max 8 SSD/SAS disks. Haven't tested bhyve yet, but I don't expect it to be faster or more stable than KVM (if you ignore frequent kernel updates ;-) regards > Gesendet: Mittwoch, 08.

I didn't spend a lot of time trying to get virtio devices working when I couldn't find my disks. But all the expected devices did 'just work' when I switched to full virt.

Re: Running OpenBSD on Hypervisor
Hi, ok it's not nice to ask general things I got it :( So basically I like to know what kind of Hypervisors are used out there and work for people. With that input I can look more closely into some of the Options and check out if the fit my needs. I was not fully aware that there is a OpenBSD version too. Since I plan to just run OpenBSd guest I take a look there too. In the end I want to figure out which of these options come close to things I want to do. So if VMware wants me to pay a shitload of money just to get replication without inventing the wheel again to make it work on a free version I like to take a look at hypervisor that can do it or is at least not that costly.

Re: Running OpenBSD on Hypervisor
I have OpenBSD (and FreeBSD) running on Linode VMs (on a KVM host) and it works well enough. I'm more than hazy on the details, but the issue as far as I'm aware is that OpenBSD does not yet have full support for virtio. So I need to use full virtualization for it to recognize my disks and network devices. Presumably this affects performance, but I haven't gotten into testing it much and haven't noticed it in my (admittedly light) use so far. At home I have FreeBSD running on Hyper-V and it works well too. But FreeBSD has better support for the virtio drivers so I'd expect it to perform better in both cases. Disclosure: I work for Linode.

Not even USB handles obsoletion(sp?) very well, even if adapters exist, but that is just confirming Nicks story to be valid. What if usb4 shows the same issues, then a usb4->3 usb with a 3->2 hub after? All so that I don't have to move the data every X years... -- May the most significant bit of your life be positive.

It was really basic and as simple as possible design and even compatible with plain SR-RAID1, but still was able to detect and self-heal corrupted block too. So if data correctness is your mantra, you don't need whole ZFS for it. Well, I've not submitted my code yet for the second attempt (first you can find in the archive) since I got kind of stuck in rewrite for family/life reasons but I still keep my hope on it and also hope it'll be delivered sooner than HAMMER2... This sounds very good! For my purpose I need less than a Raid continously checking integrity. It would be enough if it is possible to check integrity and correct data from time to time by issuing a command. Few questions: (1) Where are the checksums written? (2) Where are the metadata of Raid 1 / Raid 1 with Checksum written? (3) Can I take a disc from the Raid array and mount it somewhere else as a normal ufs single disk? (4) Well, sooner than Hammer2, but when? :) -- On Tue, 7 Mar 2017, Nick Holland wrote: The point is, you can't design ONE box for ten years of life. With modern SSD tech, I suspect you won't see a SATA port on a computer in ten years. But we can try to speculate. I guess, we will have USB Ports for long time. You see that the old RS232 is still alive. And we will have adapters to read old discs. I fear, the problem will be the firmware of modern discs written on Eprom. We cannot compare old discs with modern ones also due to the density of the data. The same could be said about the tapes. We do not have the experience. Yes, raid does not substitute backup, and one must keep the system alive and mutate it when necesary. There is in my opinion till now no solution for archiving electronic data. Continous migrating is too expensive. Rodrigo.
