What would you call Xbox One system, a hypervisor or OS?
http://wccftech.com/xbox-one-architecture-explained-runs-windows-8-virtually-indistinguishable/

If the article is accurate it would have to be a hypervisor. With a dom0 running an anorexic windows 8.

Sounds like they use the term RTOS as a code for hypervisor. They say it is an RTOS but then point out that it is not an OS (in that it doesn't run apps) and that it is a hypervisor (in that it hosts Windows 8.) So either their name is wrong, or their description is.

Ok, I didnt read the article, I commented based on things i heard from Paul Thurrott.

So I'll admit my understanding might have been wrong.

As a side note, Xbox one has been upgraded to Windows 10 now....

It's weird that the article claims it's a partition not a VM....

Partition and VM are not competing concepts. Lots of VMs are partitions. One thing (VM vs physical) is about how it runs. Partition vs. something else is just where it is stored. Nothing in saying it is a partition suggests that it is not a VM.

Now we only have the article to go on, but the article seems pretty clear that it is a VM. But what it really is, no idea.

@scottalanmiller I not quite at that max but pretty close at 56TB in a single volume local storage. Running Win 2012 R2 VM on Hyper-V 2012 R2 hypervisor. So far so good (2 yrs now). No issues other than that initial backup was a real b1tch but now that it's incremental, it's all good. No other caveats that I'm aware of.

@scottalanmiller said in Native Virtualization For macOS:

Had no idea that Mac OSX had a native hypervisor framework built in.

Hypervisor is available on Mac OSX from Yosemite.

https://developer.apple.com/library/content/releasenotes/MacOSX/WhatsNewInOSX/Articles/MacOSX10_10.html
Hypervisor (Hypervisor.framework). The Hypervisor framework allows virtualization vendors to build virtualization solutions on top of OS X without needing to deploy third-party kernel extensions (KEXTs). Included is a lightweight hypervisor that enables virtualization of the host CPUs.

@scottalanmiller said in Replacing the Dead IPOD, SAN Bit the Dust:

Also the needs of a SAN are different than the needs of a LAN. So you likely want different switches. I'd love Netgear Prosafe unmanaged on my SAN but would generally prefer Ubiquiti EdgeSwitches on my LAN.

Any opinion on Unifi Switches yet?

We use one in the lab and it's been great, but we aren't pushing its limits or anything.

@BRRABill said in Running Xen Server from a USB Drive.:

If I was doing it over again from scratch, I'd probably not use USB.

That being said, I have not had any issues thus far.

Are you redirecting logs?

Yes.

A really nice thing about XO is you can import and not power on.

So you can remove the NIC and then power on. If it works, you know you're in good shape.

Server is back online now. Bringing the files in one by one and making sure they had the right name seemed to do it.

It goes to 11, so it must be better than the ones that only go to 10.

Sorry, can't help myself sometimes.

Good information, always like to see more about selinux.

@cakeis_not_alie said in What is Real Hyperconverged Infrastructure?:

Marketing lingo dispensed with, hyperconergence is ease of use. It's IT infrastructure for people who don't have time to fuss over IT infrastructure. And by that definition, Scale has served me extremely well. So kudos to Scale...
...and long may the Scale Legion reign!

This.... very much this... They do it extremely well!

We are long past the point where running systems non-virtualized is considered acceptable

/me looks around at servers

I think it's ok to not virtualize 🙂

Doesn't BB cluster their entire farm? I thought virtualization was an effective necessity at that scale. You manage the servers without them being clustered in any way? I thought that the pods were nodes in a single farm

Oh they're clustered. I was thinking of a specific pod not being virtualized by itself. As in they aren't running a hypervisor. And we do have virtualized stuff around too. 😛

That cluster is really the virtualization, the nodes are below that level. We had another thread discussing this previously. Clusters are not always virtualized at the node level because the node is like the CPU, not a server and the entire cluster is really the computer and the cluster manager is the real hypervisor. Workloads run on the cluster, not on the nodes. Each node remains replacable as just part of the overall "Computer" which is, virtualized.

Sorry. Cannot do that.

Cannot do what?

Get back to the problem

You take your thread hating ... hate elsewhere!

@scottalanmiller The 2nd line I "edited" with a s/o!

@Dashrender said in XenServer Live Adjust capacity of drive that is shared:

Would he really need to reboot if he's adding another 'disk' copying data the removing the old disk?

Depends on the guest OS and applications using said space.
