You can't mine via using a GPU in a VM anyway, so you're barking up the wrong tree.
You can if you run an AMD CPU or an Intel CPU with VT-d support (note: not VT-x).

can cgminer be used for mining twister blocks?

There was a minor packaging error in the 3.9.0 source tarball which would make bitfury code not fully compile support for bi*fury devices unless drillbit was enabled as well, so I've uploaded updated tarballs with only that one change, they will be tagged 3.9.0-1. There is no other change in this code so you do not need to update if everything's working for you.
I have been working on writing a nanofury driver (using direct USB communications as per our USB device driver model) but it is proving rather challenging so it appears that it will be some time before nanofury support is in mainline cgminer at this stage.

I meet a very troublesome problem,and I ask for your help.
My host OS: Win7 ultimate sp1(x64)
Graphics card： ATI Radeon HD 6850
When I mine many coins based on scrypt,cgminer can run smoothly in my host OS.But I want to place cgminer and all coin's wallets into a virtual machine now,because my antivirus software always prompts that there are many viruses in cgminer and some coin's wallets. So I installed VMware workstation(10.0.1 build-1379776) today,and converted my physical computer into a virtual machine by using "Virtualize a Physical Machine".
But cgminer can't run in the virtual machine,and it prompts "No devices found". So I am ready to install the graphics driver,but I find that the graphics driver can't be installed successfully at all in the virtual machine.
So,I want to know:
1: Can cgminer run smoothly in a virtual machine?
2: If it can,how should I set the virtual machine？
My cgminer is downloaded from the link:

Did you notice https://bitcointalksearch.org/topic/m.4086475 ? It works quite well for me. Do you do a rewrite or do you just try to integrate into mainline?

So, yeah, just because you suck at mining doesn't mean everyone does.
No, I just don't rip people off selling ASICs I bought.So, yeah, just because you suck at mining doesn't mean everyone does.
You may not care about ripping people off - meanwhile I can do well without ripping anyone off.
My $ input to Bitcoin was 2.5 years ago when I bought a rig that paid itself off that year.
Everything else has been minor things.
Oddly enough I've made quite a bit more than that now.
Though, my >700GH/s at the moment (and increasing regularly) says I don't suck at mining.

However, you lost BTC. The BTC price paid for said items at the time they were bought is greater than the BTC they have produced.
Well, no, that's false, but hey don't let facts get in the way of a good argument.
I've never bought BTC for fiat, every BTC I've mined has been reinvested or cashed out to fiat.In fact the early Block Erupter boards and AMUs were so over priced that even I (who got an AMU from FriedCat - probably one of the first of anyone not inside Asicminer) have still not made 2 BTC on it - that was the price they were then, though I didn't pay any BTC/Fiat for it, and I expect to never make 2 BTC on it.
Go check again.
I paid for the ASICMiners using BTC I mined using GPUs. GPUs that were sold for more than I bought them for (bought cheap off eBay and sold for more than I bought them 6 months later when more folks wanted those GPUs for mining). So, only fiat spent was the GPUs, which I got back. Power was paid for by fait received after selling BTC.
I have never spent fiat on mining hardware. It's always been BTC produced mining.
So, yeah, just because you suck at mining doesn't mean everyone does.

Meanwhile, on an on topic note, anyone who has BitFury boards, with a V1 or V2 controller, I've updated the driver in my git and it should work with either now.
https://github.com/kanoi/cgminer
I've tested it on BlackArrow hardware.
One V2 controller with 1 board, the other V2 controller with 6 boards: 3onSPI1, 2onSPI2, 1onSPI3.
Both work fine.
I, however, use Arch coz I find it more reliable on the RPi.

ckolivas any plans to do a antminer firmware like you done with avalon and knc miner ?
I echo this, compiling the custom version with Antminer support is very difficult and (in my experience) far from stable. Would love to see the Antminer drivers integrated into the official CGMiner.
Hopefully Bitmain will make the required changes so the two can be merged
nwoolls has drivers working for "The other miner that can't be mentioned", and will be merging them to it's git soon. Perhaps ck and kano can do something with his code?

Thus your profit is less than if you had simply bought BTC instead.
(also you need to subtract the running cost and time mining that would not have been necessary if you only bought BTC)
(also you need to subtract the running cost and time mining that would not have been necessary if you only bought BTC)
Agreed on the first point.
However, my running costs are essentially zero when averaged out across a year, and over the year I've been mining I've spent essentially nothing in fiat to keep my BTC production around 1BTC every 6 weeks. 1BTC every 6 weeks means I can keep up with increase in difficulty by buying new hardware, and sometimes my older hardware is sold to top up that BTC fund - I sold my 10 Block Erupters and bought two BlueFurys. Selling the Blues paid for the 10 Antminer U1s. Without spending a fiat penny I've gone from 3.3GH to 5GH to around 20GH.
You also have to consider that I'm not really in this for profit. I have a good job that pays me enough that I live comfortably and have enough left over at the end of the month to not only save, but spend on my hobby of building PCs and buying little things to tinker with. Mining is a hobby. Some people play games on XBox. Some people go and piss £100 up the wall on a Friday night. I mess about with my miners.

Those ASICMiner devices have always been overpriced. ASICMiner and Avalon units consume way too much power. Those BFL Singles are decent devices. Those AntMiners look very promising. KNC or BitFury are amazing devices. I dare you to ask anyone who has any of those and see if they're losing money.
My V1 Blades have paid for themselves a few time over - they've been totally solid and reliable, and just hash away in the corner with zero intervention. Same with the Jalapenos.

The BTC difficulty is increasing because more and more people are buying newer and newer hardware. The network doesn't just increase by 500x in a one year span without people buying the hardware, and mining on them. CGMiner is at the forefront of running those millions of dollars of hashrate, BTW.
And as far as your ASICs are concerned, it's not Con's fault people bought a bunch of BEs or a Jalapeno and realized they're too expensive / hard to maintain to successfully mine any coins from them. Those ASICMiner devices have always been overpriced. ASICMiner and Avalon units consume way too much power. Those BFL Singles are decent devices. Those AntMiners look very promising. KNC or BitFury are amazing devices. I dare you to ask anyone who has any of those and see if they're losing money.

I know how difficult is calculated, I have been on this for almost a year, as I said before, i build several farms (5, one is mine, the other as a consultant/technician for investors) and the only ones making real money are the altcoins, the only way to make real money mining bitcoin is buying the chips and produce the rigs yourself before anyone else, or better.... design the chips yourself and don't sell them, use them.
I will get ROI with my Fury's probably between febrary and march, I already achieved ROI with my Blades, but you know what, I can make ROI in alt-coins in 3 months, sometimes less.
I never talked about loosing money, just not earning enough to make it worth it, period.

I know im never going to make any ROI on my set-up, but I like building and maintaining it and like to "support the cause" that is Bitcoin

What is annoying is the ASICMiner Cube - it's unstable at best, uses quite a bit of power. I'm not sure it'll ever pay for itself, but this winter it's keeping the living room about 2C warmer than usual this time of the year, and all summer it'll cost nothing to run thanks to free power.

I'm not maintaining mining software to help people make profits. I'm maintaining a bitcoin miner because I believe in bitcoin, and while miners are primarily interested in making a profit from mining, I'm interested in promoting and supporting bitcoin, which needs miners and mining software.
Hello Ckolivas
I understand your point of view, thank you for explaining it.
Miners always where a not very welcome necessary evil, I saw it in the labitconf conference in buenos aires, where practically the entire mining thing was avoided at all cost by the pure believers in the coin.
The truth is... mining has become really expensive business now, and great part of the people involved in it will expect profit in return of such a time consuming job.
I have 1 farm and i am consultant for another 4, and takes about 60% of my time, for such a time consuming task I expect to get profit, and while I keep btc for long term savings, I exchange a good part for fiat to live in the mean time
I hope some day I will be able to pay everything in btc, but we are far away from that just yet.

I had read that a while ago, it says he will do it, but not why.
why keep supporting something that does not generate money and kill what is generating money, that is the alt coins.
I make 10 to 1 in altcoins vs bitcoin mining.
and i have several asics, but they are pointless because they are too expensive, takes way too long to get here an make them work, by that time, the difficulty is so high that they produce next to nothing, in altcoins that doesn't happen so fast, so you can do profit, that's why I ask that.
of course he can do what he wants is his program, is a great program, but i was just curious, nothing more.

Did you read the whole thing? It DOES say why. Let me crop out a few parts:
I am making a conscious decision and taking a stance to only support bitcoin by doing this and will consider all discussions regarding alternative cryptocurrencies as offtopic from here on. It is absolutely clear that we are in a stage where only ASICs matter in mining bitcoin, and cgminer is moving with the rapidly changing landscape that is bitcoin mining.
I honestly think all the alternative cryptocurrencies will go nowhere. The only reason to mine them is to find something that can be profitable by converting it to BTC.
The BTC difficulty is increasing because more and more people are buying newer and newer hardware. The network doesn't just increase by 500x in a one year span without people buying the hardware, and mining on them. CGMiner is at the forefront of running those millions of dollars of hashrate, BTW.
