Read this. especially if you're using the community version.

@jt1001001 It will only work if the CPU is 64 bits but the Vmware version is 32 bits.

Oh should have I posted my reply on SW instead?

He sees it here, too.

@msff-amman-itofficer said in Open Source Hypervisors: do we really have them? do we really need them?:

my take on this:

ESXi free is limited, 8 vcpu per VM and that limit can be easily reached limit.

It's easily reached if you starve a VM of IOPS or RAM and it's spinning cycles waiting on IO. In reality VERY few things need 8 vCPU. I've seen The ONLY exchange server for 5000 users not need that many resources.

Given modern Skylake hardware, and 4Ghz Intel Xeon Cores's if your hitting the 8vCPU limit I'm REALLY curious why your not willing to spend the one time ~$200 per host that is the Essentials bundle to get some more features is a rounding error in your budget (it's like less than a $1 a day per host).

Keep in mind it is not per hosts, but ~$600 per three hosts, so for much of the SMB that's either $300 or $600 per host and makes things like future upgrades potentially a problem. And $600 per host is enormous for the SMB market. Absolutely staggering. Given that 90% of the market can't even cost justify a server, let alone a server with that much additional licensing.

On a single host, how much value is that $600 getting an SMB versus getting free, unlimited use virtualization with $600 of faster hardware? When we are talking a $3,000 server, an extra $600 is anything but trivial.

The "only $200 per host" is really "holy crap, $200 per host with a minimum of three!!" That's not at all a small number, not in the SMB market. And especially not in an SMB market outside of the US.

@black3dynamite said in Always Virtualize Domain Controllers:

It would help if Microsoft would also recommend to always virtualize domain controllers.

They do. They've been really clear on that from everything that I have seen.

Last recommendation seen on microsoft official docs - maybe the italian ones: virtualize the AD first instance, keep a phisical one as second instance...

don't understand the logic of this. but hey: their offical business support said I was not allowed to virtualise more than 2 VMs on hyper-v, even if there were linux 😕

@obsolesce It's called paravirtualization. And Xen has done it since the 1990s 🙂 Only Xen could do it for the entire VM, not just the drivers.

I should add that this is not exactly true. "Windows Dedupe" is not available in Hyper-V, which might sound obvious, as it is a Windows feature. But Hyper-V does have ReFS which has a new feature in 2016 that is not called dedupe but acts like a really light dedupe option. So while "Windows Dedupe" is not available, there is a dedupe technology available to use. But it's not a great one, it's super basic. But it also has like zero overhead, so can be pretty nice to use even if it doesn't do a lot.

I just face palmed reading that first paragraph:
New features
LVM RAID support
One of the biggest features of blivet-gui 2.0 is support of LVM RAID. When adding a new LV, you can now choose RAID level for it. LVM supports the same RAID types mdraid does but you can choose different level for every logical volume so it's more flexible than using LVM on top of an mdraid.

LVM still uses md raid, just like you would normally.

That said, people like their gui for all the things, why not have yet another tool to manage everything.

@Tim_G said in Caching Needs and SSDs:

you have something on I/O path going wrong ;(

What do you mean? Everything looks good and appears to be going smooth according to all monitoring. No errors or performance issues.

It's been doing a very good job the past couple years. I keep it fairly updated. So if something recent broke something on it, let me know and I'll hold off on updating.

@Tim_G said in Sage 50 Quantum in Hyper-V VM:

So when they are ready to make their software production-ready, it will be the other way around.

Exactly. Like if they ONLY supported VMware or ONLY supported Hyper-V or ONLY supported Windows we'd understand. Those are all potential production ways to run software. But a physical deployment? This means that they've never tested and don't support ANY production environment.

There is a big gap between having "one tested environment for production" and "not tested or supported for production."

Exact same reason we dropped FogBugz. They only supported non-production platforms.

@RamblingBiped said in KVM Installation and VM Creation on Fedora 25:

I did an article about a year ago about setting up KVM/QEMU on Ubuntu 16.04, it might be of some use: https://www.ramblingbiped.com/build-a-kvm-qemu-hypervisor-on-ubuntu-16-04-server/

I also wrote a short blurb on automating VM creation using a pre-built VM template, virt-clone, and virt-sysprep: https://www.ramblingbiped.com/build-a-kvm-qemu-hypervisor-on-ubuntu-16-04-server/

That is very helpful. Thank you.

I still love XenServer and XenOrchestra as my one of choice for now. But then i'm only running small Linux/Windows servers on it anyway like Zabbix, Radius, Unifi. Nothing full production like the DC or Dynamics/SQL

Same here, but cautiously watching...

Calligra was always okay. Not great, but certainly not bad.

@Tim_G said in How to Download Hyper-V 2016:

Yay! Finally something real to link to.

That's why I made it, I needed it this morning 🙂

5.8.1 was release earlier today. My test build is failing, but haven't had time to dig in and find out why.

I totally understand workload being a legit reason. It intrigued me to, but to only have a week to complete some of those designs and work a normal job is rough.

Didn't @art_of_shred recently get a Cameyo?

I don't know about recently 😛

Maybe at MangoCon it can make a Cameyo appearance!

Thank you for your feedback on 5nine Manager, guys.
Our goal is to provide an intuitive yet powerful product for complete centralized Hyper-V management experience.
It is now de-facto standard for managing environments with up to 20 Hyper-V host.

Now we are going even further, and prepared a great product, that can help you scale, segregate user management roles with RBAC, automation support and even more. Enjoy!

Beta program for 5nine Manager Datacenter is now open to public:
