Having used both Xen and KVM, I gotta say that I find KVM to be much easier to work with.
I've found them both really easy
XenServer was easy, but just didn't mesh well with how I wanted it to work. KVM was a bit easier to get set up in my remote environment.
How so?
In my hosted lab, it wanted to take over my only public IP address. XAPI took over ports 80 and 443, so I couldn't run a web server or anything on those ports. I never was able to figure out how to change it -- I even asked here a time or two.
KVM went right in and gave me zero hassle.
Interesting.. What ports does KVM use for management? just typical SSH?
Yepp.
Is there no web management for it then?
Sure, there are options, but they can be run as VMs or on ports other than 80 or 443 (WebVirtMgr, or virt-manager on another Linux box).
No firewall?
Sadly, nothing other than IPTables.
You had your platform server attached directly to the Internet?
Yeah, he mentioned that earlier. Sounds like he basically installed XS into a vultr like session.
Close. Physical box hosted in somebody else's closet.
And they wouldn't let you put a ER-L in front of the server?
It's hosted with KimSufi (OVH), so, no. They wouldn't. Their job is to image the box and put it online and give me necessary details.
Oh, well stop using them
Why? They work so well, they're cheap, and I have my data backed up somewhere else.
I feel like you just described them not working well, then say that they work well
What do they cost for that?

You assume I want something else in front of my box connected to the internet -- I don't. My idea of working well is can I access it when I want, and does it work when I click the Go button.
It's $25 a month 8-Core Intel / 16GB RAM / 2TB SATA / 100 mbit unmetered internet / 1 public IPv4.

That's not too bad. Of course, I'd argue that it would be way cheaper to get four people together, and get a "real" server in colocation and split it. Each of you getting way more than this.

Cheaper? Yes. Easier? Nah. I don't want 3 other people mad at me when reboot the host randomly.
It really isn't bad, and as far as I can tell, they've had amazing reliability at the facility.

You can do just SSH. But QEMU has the option for HTTP/HTTPS as well.

I bet that they are using something like SM Blades.

It's actually pretty cool.
-
Ah, custom blades.
-
@storageninja Nice find!
-
Wow, this really is major news. I'll third that this might be the IT announcement of the year.
-
Where are all those "Citrix'ites" that always puffed their chests talking 'bout how great XS was since AWS used it!
I should go troll them on the XS boards! -

that is pretty cool. does the technician at the end really need a hard hat?
-
huh - water cooling at the server level.

@scottalanmiller said in Amazon AWS Leaving Xen for KVM:
This is enormous news. This, more than anything, signals the end of the road for Xen. A very sad day.
That is huge... how did I miss this the past few days?
-
Same OVH that went down today, because they lost power and none of their generators (if they had any) powered on?...
-
btw, isn't the Google Cloud Platform based entirely on KVM?
-
@dashrender said in Amazon AWS Leaving Xen for KVM:

Yeah, a lot of datacenters use liquid cooling of some sort. It generally saves money on cooling, so is an easy choice to make for companies that run their own datacenters. Obviously not at all popular with colo places as it generally requires special cooling blocks on the servers.

I totally get water cooling of the space, I've just never seen it actually go inside each server before - I mean I think it makes sense, at least on the surface.

As others, i dont know how i missed this.
As one of the few remaining XS guys i suppose i need to start looking for other options now.
