Is anyone using the Hyper-V Server 8 (standalone) beta? I don't have much experience with Hyper-V and I'm wondering if VMs created in Hyper-V Server 8 are backwards compatible with Hyper-V 2008 R2.
 
I would say no. Considering the new Win8 Server uses the VHDX file format now.

it's so unstable that you would be wasting your time, i tried it on a system with 16 gigs ram and all the ms updates and it was a pile of shit and kept crashing, ran 2008r2 with hyper v on the same box and it was stable 100%

server 8 is a pile of shit.

What system did you try it on? I've used Windows 8 Hyper-V on everything from a microserver atom to an 8-socket (80 physical core) westmere-EX and everything inbetween without any glaring errors.

Edit: To answer the OP's question. You cannot mount a vhdx file with Server 2008 R2 SP1 (only supports vhd). I am unsure if this will change in the future.

I also have had up to four blade servers running server 8 in clusters and no clusters. Never once had a error or failure one. At one point i was running over a hundred vdi machines between the bunch.

You should try again.

Thought about it actually, I do have a technet account so 2012 might be in there next year :)

I should throw it in another Vm and try it, i grabed both server & desktop 8.

Been running on my new system for a couple weeks now with 32GB of ram and 6 VMs running the whole time. The only time it was unstable was when I had hardware issues (bad ram). I'm really liking the new features of S8 though.

Installing it to play with it. Think ill order 48gigs of ram this week so I have a totll of 64 at home, on my R415
 
If you use the VHD format, they are backwards and forwards compatible. If you use the newer VHDX format, no it isn't backwards compatible.

I'm using Hyper-V 2.0 via a full 2008R2 install, I plan on migrating to Hyper-V Server 2012 Core (free) for my host sometime around November of this year.

I've found (2) gui tools that give the interface enough management ability that "others" in the IT department (can and will be) willing to manage it in my absence.

Hyper-V Core Server 2012 = Less patches, better, faster, free...awesome.


I swapped out a HP ML330 G6 with 8GB of ram,16 cores, RAID1 2x78GB SAS drives running 2003 R2 for an...

Dell R210 II Xeon i3 w/VT quad core, w/32GB ram and RAID 10 4x500GB SATA drives running Server 2008R2 with the Hyper-V Role.

Old machine (1 OS) idles 438 watts 5U of rackspace, as a DC
New machine (5 OSs) idles 78 watts 1U of rackspace , DC, AV mirror, Server 8, Hyper-V 8 core, Host OS and Windows 8 consumer preview.

Since this is in a closet with no extra AC, The change is huge. It rarely using more than 10% of its CPU and sits about 18GB of RAM in use including cache. Its also nice that the UPS can stay online over 2 times longer before shutting down the equipment.

The only issue i can see, is licence for the amount of cpu's and ram. Right now I only have 24 gigs in my Xen server, but i plan to move to 64 and RUN LOTS more vm's. I wonder what ms is going to do about this on server 8..

I wonder if we will be able to use our tech net & use more than 32gigs of ram.
 
Not out yet obviously but there was Hyper-V server (2008) and Hyper-V server R2 (2008 R2). They're server core installations where hyper-v is the only role.

Ahh interesting.

I run two servers that are 2k8r2 in a data-center and run Hyper-V on them.

Was looking at this as an idea, but its looking like remote management over internet is probably not the best solution unless someone has a good idea.

I already have a openvpn appliance I use for half assed things but it was moreso setup so that I could use some ghetto firewall rules once upon a time.
