What is Digg?114 Comments
- Jacob, on 10/12/2007, -4/+58flash 9 is out for linux, why don't you just install it. well beta still i think but it works fine for me.
- thcobbs, on 10/12/2007, -4/+40They need a different acronym... KVM is already highly-ingrained for Keyboard-Video-Mouse.
- mooninite, on 10/12/2007, -0/+29I'm going to be a bastard and reply to the 1st comment to get attention, but it seems no one knows what KVM is and they won't bother to Google it.
KVM -- HARDWARE VIRTUALIZATION : *requires* a VT capable CPU (such as the Core Duo in this video)
VMWare -- SOFTWARE VIRUTALIZATION : any CPU will work with it
Which is faster? The hardware kind of course...
Your P3/P4 or older AMD CPU will NOT work with KVM. - bglodde, on 10/12/2007, -1/+26That is really impressive. Looks like it's running pretty snappy too.
- scratched, on 10/12/2007, -4/+28More than half of the software running on a linux machine is in some form of beta to begin with usually, why not just install flash 9 beta also. It's pretty stable.
- coredump0x01, on 10/12/2007, -3/+20Apparently 51 (and counting) diggers cared enough to digg it to the front page. Idiot.
- coredump0x01, on 10/12/2007, -0/+17The combination of the KVM module and the core duo's virtualization support means that the kernel can devote an entire CPU core to the OS running in the virtual machine, which means processes on the host OS will not drastically drop the performance of the OS running in the virtual machine. It's similar to the way 3D graphics cards speed up graphically intensive games which stand-alone CPU's could not single-handedly render.
- inactive, on 10/12/2007, -0/+15So what is it about KVM that lets you run virtual machines so much more quickly than standard VMWare does today? That virtual machine seemed to respond insanely quick!
- rapiddemon, on 10/12/2007, -1/+15There is no x64 version of it, so he would need to recompile his web browser if it isn't already 32bit.
- zc_au, on 10/12/2007, -0/+14arrr let me think
people who run linux as there default core OS and need to do something in an windows desktop env for 30 mins
so they dont need to reboot there core os to jump over to an second OS
or so they can do testing in diff browsers at real time
on a single pc
testing how something looks in Firefox and IE
or something else
where windows env is needed for short time on a linux desktop - ahhell, on 10/12/2007, -2/+15Wow that seems pretty speedy too.
- MikeN, on 10/12/2007, -0/+13In this case KVM stands for Kernel-based Virtual Machine.
- ClayDragon, on 10/12/2007, -2/+15It seems that he has the wobbly effect not only on his desktop, but on his hands holding the camera as well.
- vuke69, on 10/12/2007, -0/+11Yes for a long time in fact.
What KVM and XEN allow (and also vmware esx, but not normal vmware server), is for you to get much closer to bare metal with your virtual machines and get potentially greater performance, as well as the direct use of hardware devices inside of the VM (raid controllers, video cards, whatever). Although there is much work to be done on the second part. - wiremonkeymommy, on 10/12/2007, -0/+10pure beauty
- mooninite, on 10/12/2007, -3/+12There are open source equivalents to those dvd programs. Ever heard of ffmpeg? If not, then you need to start opening your mind and looking at more software that doesn't have a .exe at the end of it.
- topcat5, on 10/12/2007, -7/+15It runs Windows better than Windows runs Windows. LOL.
- inactive, on 10/12/2007, -0/+8Wow, that's really fast!
- x3nos, on 10/12/2007, -0/+8Check out http://digg.com/linux_unix/Finally_user_friendly_virtualization_for_Linux for a bit more background on the Kernel-based VM. More howtos and such will be more available as the 2.6.20 kernel is released stable.
- SirBotchness, on 10/12/2007, -1/+9tell us how you really feel.

- thekidder, on 10/12/2007, -4/+11Try "KVM virtualization" in Google.
Maybe you just need to learn how to search better. - andreyfedoseev, on 10/12/2007, -2/+9VMWare isn't opensource software
- Ssullivan, on 10/12/2007, -1/+8@adiosk8
No, this is hardware supported virtualization. - tuffy, on 10/12/2007, -2/+8I haven't tried DVDFabDecrypter yet, but DVDShrink works in Wine 0.9.27 right now. Most DVDs can be ripped with vobcopy, shrunk down with DVDShrink and then the resulting ISO can be sent off to cdrecord for burning.
- inactive, on 10/12/2007, -0/+6its funny, all these handhold-a-video-camera guys showing off GNU/Linux (Beryl).
You can record the videos using a default Beryl plugin. - vuke69, on 10/12/2007, -2/+8KVM... Come on guys you have got to be kidding me, you cant come up with a name that isn't already an industry standard acronym, and therefore impossible to google for?
Other than that, cool, the more that virtualization advances, the better. I have been using vmware server heavily at work since it became free, and I have tried xen, but it is very clunky to get a new vm created. I am always looking for more options. - inactive, on 10/12/2007, -1/+6So for those of us who still associate KVM with keyboard video mouse, what do the KVM acronym used here correspond to?
- vixenk, on 10/12/2007, -0/+5If you're looking for a native gui solution, you might like dvd:rip or k9copy if you haven't tried them out already.
- codyman, on 10/12/2007, -5/+10Hmm... if they get this working good, and if DVDFabDecrypter and DVDShrink both work in it, I might finally make 100% switch to linux....
- asspants, on 10/12/2007, -2/+7if your windows is crashing all the time you've got something wrong with your hardware.
my xp box has gone for over 99 days without a reboot, and that was my daily use machine.
windows used to crash. - theonewho, on 10/12/2007, -0/+5For those dvds that have the newest copy protection on them (arccos/ripguard) the windows program called RipIt4Me (ripit4me.org) works using wine now. That program uses DvdDecrypter, and FixVTS to rip, and DVDShrink to make it smaller.
Couple of notes, for Ubuntu Edgy you man need to install an older version of wine to get it all working at first but wine can be upgraded again later (see http://forum.digital-digest.com/showthread.php?s=e2718a18388096a1af07dce69cd3a5ec&t=74809 for info on this). Also, the windows version in wine needs to be set to NT 4.0 for DvdDecrypter to work.
I would personally like some native linux programs that work on these newer copy protection schemes, but until then RipIt4Me has worked perfectly so far. - drdank, on 10/12/2007, -0/+5tuffy: DVDshrink works well for me under wine as well. Instead of that middle step, I can just use DVDShrink to back up the disk to an iso file and burn with K3B. Couldn't be easier.

Wikipedia, buddy. All Core Duo's except T2300E, T2050, T2250 support virtualization. - coredump0x01, on 10/12/2007, -0/+4What i don't get is, At the end why does he use the camera to zoom in on the window title instead of using the zoom plugin? Would've been easier to read that way too.
- msgyrd, on 10/12/2007, -0/+4@idntunknwn:
I know VirtualDub isn't exactly the same, but Kino ( http://www.kinodv.org ) does everything I need for video editting. It's not a 1 for 1 replacement, because it's not supposed to be a program clone, it's an independent program. - faddat, on 10/12/2007, -1/+5This is without a doubt "the new hotness". In fact, this breaks down the biggest barrier to me running windows at all on my computer-- the fact that it crashes and requires restarts often. With a system like this, it's OK-- windows might crash, but I just start it again from my OS already running. Onwards and upwards with this really cool tech. Lastly, am I correct that this will work on both Intel Core 2 Duo's and AMD X2's?
Yeah, this one is sweet. - suprchunk, on 10/12/2007, -0/+4I agree. That is the only thing holding me to Windows: the reencoding, easily, of my movies so that I can archive them and edit them to my heart's desire. Although I don't use the same software as you, the ability to edit and burn DVDs is holding me back from kicking MS to the curb completely.
Oh and I don't want to use Wine. I really want a native app to Linux to use, but until that comes out this method seems way better than wine to use. - xertys, on 10/12/2007, -0/+4QEMU is an emulator and thus is very slow. There's a kernel module which tries to virtualise rather than emulate, but it's closed source.
- delta013, on 10/12/2007, -0/+4@mooninite
Is there a list somewhere of VT capable CPUs?
Also, can you run windows games with KVM? - coredump0x01, on 10/12/2007, -0/+4@dzapffe19
Strange, I watched it full way through with the latest flash beta. What version of firefox are you using? Also make sure you're using the latest version of the flash beta. Also be sure to temporarily disable any adblock extensions. - tlsarles, on 10/12/2007, -9/+12I agree. I'm running linux on a Power PC. No Flash :-
- msgyrd, on 10/12/2007, -0/+3Another vote for k9copy. If you don't like running DVDshrink under WINE (or it wasn't compressing for you), k9copy will probably fill your expectations. It will also rip directly to .avi (you can specifiy the size), or reauthor the DVD to strip off the menus/advertisements, or just behave like DVDshrink. It's a KDE app, but runs in Gnome just fine.
- therightrev, on 10/12/2007, -1/+4Get OS2/Warp running in a VM on an XP box and then you'll impress me. ;) (It's a bitch to do and that momentary rush of getting it working really isn't something you want to share with other people - it's best kept to yourself in a dark empty room... trust me...)
- patricks, on 10/12/2007, -3/+6we sure can.
http://digg.com/tech_news/Digg_Ubuntu_AJAX_Google_YouTube_Ruby_On_Rails_Kevin_Rose - ceralor, on 10/12/2007, -1/+4I've been able to directly copy from a regular DVD video to a DVD-R DL disc using solely k3B. Worked very nicely, and played back not only on my computer, but also my DVD player. Great way to archive stuff if you're afraid of breaking a disc or relatives stealing them, which has happened to us multiple times.
- mooninite, on 10/12/2007, -0/+3You need to look for the extension "vtx" and not "vt" but as the comment above says, your CPU will not support it.
- jdong, on 10/12/2007, -0/+3That list unfortunately is not comprehensive... the Core Duo T2300 for example does support virtualization, but the later reincarnation of it (T2300E) doesn't.
jdong@jdong-laptop:~$ cat /proc/cpuinfo
model name : Genuine Intel(R) CPU T2300 @ 1.66GHz
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc pni monitor vmx est tm2 xtpr
Note vmx, that's Intel's virtualization extensions. AMD's would be listed as "svm" instead of vmx. Look for those keywords in your /proc/cpuinfo for the most reliable indication of if your CPU supports virtualization.
NOTE: Despite some CPU's supporting virtualization, your BIOS may have it hard-coded to disabled, or have a toggle-option for it. When disabled, it still shows up in cpuinfo but will not be unusable.
So I guess the true story is you need to boot into a Xen kernel and issue cat /sys/hypervisor/properties/capabilities. If any "hvm" flavors are listed then your virtualization is usable. - stoppedcode12, on 10/12/2007, -0/+3The C2D will have no problem, for the x2s, you need an x2 that uses the new AM2 socket. The old x2 939 will not work.
