WSL2 tells us a lot.

First, Microsoft is really making it more known that WSL has no Linux and is just Ubuntu (or whatever) on the Windows kernel.

Second, Microsoft is making it clearer that there was no virtualization going on in WSL.

Third, now there is Hyper-V and a Linux kernel involved. So now it is just virtualizating a Linux instance on top of Windows.

Fourth, now it is much faster. That means that Linux on Hyper-V is faster than Windows on bare metal!

@Pete-S They list both the 61xx and 62xx as options for the R740XD.

Good!

What CPUs do you have in the R720 today? 1 or 2 CPUs?

Do you want the new ones to be faster or just capable of running more VMs?

I have 2 x E5-2609 CPUs in each server. I would like faster, but more VMs would be the priority.

The E5-2609 CPUs are at the low end of what was available at the time so no problem there.

Actually, are you looking to keep the old servers around for testing and such?
In that case you could just drop in refurbished CPUs that are faster and/or has more cores for very little money. If the server can take E5-2600 V2 you can get up to 12 core CPUs.

yeah, but Windows licensing is an issue, assuming multiple CPUs... for a test server, not likely worth going over the 16 cores. Not to mention the test server might require licensing (if needed beyond the 90 day test period for something).

Two 8-cores would be an option. For instance two E5-2690. They are 2.9 GHz base frequency and have 8 cores. About $100 each when buying refurbished.

About 50% faster per core (2609 have no turbo) and about 3 times faster multicore performance. Has more cache and faster memory transfer speed. Was a very high end CPU at the time. Was listed at $2000 while the E5-2609 was $300.

The fastest 8-core E5-2600 V2 CPU is the E5-2667 V2. 8 cores and base frequency of 3.3 GHz. It will likely also be an option for the R720XD. V2 uses 22nm technology so uses less power with the same clock speed and can fit more cores or run higher frequencies.

@scottalanmiller said in P2V Windows 2000 on KVM:

So this is ridiculous, but we just found out that it is actually 2003 R2, not 2000. So I assume that this will be way better.

I had a ton of issues getting mine to work - I had to run chkdsk like 15 times before it finally booted... I don't recall what migration tool I used.

For Fedora you can just do

sudo dnf install vagrant-libvirt

1 .So can ovirt be run with only 2 nodes?
2. With those 2 nodes, do you need a separate shared storage device for live migrations, etc, or can you have local storage (Like "vsan")?

@FATeknollogee said in oVirt Host Choices for Production:

@EddieJennings I would start by using oVirt Node (it's based on CentOS), it's the simplest, least hassled way of setting up.

Yeah, they have their own Node deployer, I'd generally just use that.

Very Interesting!

@mary said in Cloud Models - CompTIA A+ 220-1001 Prof Messer:

@scottalanmiller so cloud is a buzzword?

Oh yes I used to see commercials with a kid talking about the "Almighty Cloud". This was several years ago but not much has changed in the marketing.

It's absolutely used wrong all the time, but that doesn't make cloud a buzz work, cloud is a real specific thing, but almost no one uses it correctly.
