VMware or Windows 8 defect with HYPER-V

Hi
just testing W8 RP with HYPER-V. Seems that if you enable this VMware workstation no longer functions.

I think from what I remember this worked OK in the Consumer preview.

So is this a VMware or Ms bug -- I'd suspect it's VMware's bug because you could install VMware AFTER setting up your desired Windows 8 environment.

Which is a pity since if it was an MS bug it would be on a fix list before RTM / Release candidate builds.

Cheers

They cannot share VT-x from what I've found out.

If you already run a virtualisation environment such as VMWare or VirtualBox (with 64-bit VMs only), they will no longer work. The reason is that the Hypervisor doesn't expose the VT-x extension to it's virtual machines (including your new root), and so other virtualisation products can't be ran with full effectiveness. The obvious workaround to this problem is to convert your VMWare/VirtualBox VMs to Hyper-V, and import them using the Hyper-V Manager.

[...] By enabling Hyper-V on your machine, your root OS (which you use) will now run on top of a Hypervisor, which means it's essentially virtualised. It's not in the same sense as a virtual machine, as your OS will still have direct hardware access to essentials such as graphics cards for gaming etc.

Hi there
the Hyper-V stuff is great - especially on a NON SERVER OS - but I NEED VMware as well for the foreseeable future.

It might be that Ms is deliberately going out to hobble VMware . Could be a "business strategy".

Incidentally does the same problem occur with VBOX -- haven't run VBOX so I can't say.

s's strategy *might* work -since if I can get a SUSE 11.X system to work as a VM via HYPER-V I might just ditch VMware altogether - although VMware workstation has been great -- and now you can run vm's in the background like on a server the reason I was looking for an alternative has gone away.

I don't want to have to run something like Esxi on a laptop.

HYPER-V looked good on a decent 8GB intel i5 laptop. Pity about this glitch.

cheers

That's a dirty move from MS if it's true.
But yes it also occurs with VirtualBox (confirmed) and maybe Parallells and all of those trying to use VT-x.

VMware always got very stable programs, they''ll never leave windows behind.

I also like how the VM's in Hyper-V work.

Let's hope they think about this issue.

I have never been able to come to terms with Hyper-V. When you manage hypervisors which are not on a domain, from workstations that are on a domain, it's a real PITA to get everything working. It should be easy, just like the vmware client, but it isn't. You gotta jump through hoops, configured dcom stuff, etc. Bleh....everytime I look at Hyper V, I appreciate VMWare even more and it makes me forget about the high cost associated with VMWare. In my book, it's worth it.

This should not be an issue at all, when you run few Hyper-V host, you certainly don't want to run them outside a domain environment, especially if you use SCVMM to manage them.


Let's hope they think about this issue.
Again not a big issue , in production environment or in lab, you run only Hyper-V on the Server Host, their is no need to enable Hyper-V on the WS so you can use VMware WS.

Jimbon, Hobachi, your issues come from the fact that you are using only 1 pc, throw in the game a dedicated Hyper-V host server and you are in business. I run all my Server OS on Hyper-V host and all my Client on VMware WS.

In my case, my servers are in colocation facilities or remote data centers. My enterprise AD environment is NOT extended into these facilities. In these cases, if AD is required for anything, its a separate instance that is run in that environment, so my admin workstations and such are within a different domain...so the hassle certainly is there.

Hi there
OK running it from a SERVER is another issue -- but then ask why did Ms offer this facility on a DESKTOP OS.

I'm quite happy to have Ms say you need W8 server or whatever --but this was deliberately touted as a feature on a WORKSTATION OS and as such shouldn't interefere with currently installed applications.

Jist my take on this -- at least MS should have stated in the W8 "sales spiel" that if you use HYPER-V you can't run another Virtualisation program.

If given a choice VMware is going to come in first all the time for me. I to used VM 8 in DP, but was surprised when it wouldn't work together with HYPER-V, thus HYPER-V got turned off. With all the VM player appliances I have it just seems smart to stay with VM 8.

Also I like to have Win 7 running in a VM on my second monitor (of 3) all the time (use it for my MS Games that come in Win 7. Darn 8 doesn't have any).
A good reason for having 16 gigs or more.:D

Hi there
I'm actually trying it now on the "Non GUI" version of Windows 2012. Running this on a server is fine -- W7 / W8 VM's as well as w2003 server as a vm on HYPER-V is mega fine on this version of Windows 2012,

cheers
