Fedora :: Red Hat Has Been Embracing/using KVM So How Is KVM Compared To Vmware
Nov 8, 2009
I have some questions like in my other thread about vmware server vs. vmware workstation.
This one is how does KVM compare to vmware. I've been reading how Red Hat has been embracing/using KVM so how is KVM compared to vmware. Does KVM have the same performance as vmware, or better? USB support, any issues with it like VirtualBox? Any issues running both vmaware and KVM at the same time as I compare/contrast Finally are there tools to convert a vmdk to what ever KVM uses

The system's volume is way too low compared to windows vista set up on the same computer. The master volume (at the top right corner) and the player's volume is set to full and the speaker's volume is almost full. even the sound is just ok, not loud. Why can such a thing happen on fedora 10?

I thought java was opensourced, yet the Cisco ASDM (which is java based) is completely unuseable when using openjava. When I use the version from java.com, everything works as expected, including the browser plugin.

I have been using VMware Player for some time to host Fedora VMware images on Windows XP. I have been using Fedora 11 and 12 (both 32 and 64 bit) and recently started to use Fedora 13.
I use as a base the images provided by thoughtpolice. http://www.thoughtpolice.co.uk/
I usually install VMware tools and also keep the images updated (yum update) which sometimes changes the kernel.
I have recently had problems with the snapshots not having a network when I restore them. So far I don't have the problem with Fedora 11 and do have it with Fedora 12 (but used not to). I do have it with Fedora 13.
In each case the problem goes away when I uninstall the VMware tools and comes back when I install them again.
One of the symptoms is that SElinux complains about not being able to do something with /var/run/vmware-active-nics.
It looks to me that something is incorrect in the actions being taken when the snapshot is being restored. It does not happen every time and sometimes the network restores itself.
The network can be restored by rebooting the image.

I have installed the latest version of Ubuntu Linux (11.04) into latest VMware workstation (7.1.4 build-385536). I have tried to install the VMware tools ISO that came with VMware workstation but It didn't work and the installation seemed real sloppy anyways.
I installed the open VMware tools from synaptic within the guest linux and restarted, everything seemed to have been installed just fine but VMware Workstation doesn't detect it. I'm not sure if the tools are outdated, silent errors happened, or if any manual post installation steps need to be taken.
getting any form of VMware tools to run in Linux and detected by VMware Workstation.

I completed the installation of VMWare Server 2.0.2 onto a CentOS 5.4 64-bit distribution. There is a VMware virtual machine file on the server in question, and I want to activate it through the application console.
I did not see anything readily apparent that would facilitate the importing of the virtual machine file. Does anyone have a procedure that can accomplish this task?

I am running an up to date Debian Lenny system with vmware 1.08 server installed.
When I run vmware, it appears to start normally. However, when I try to open a previously created image (from a different machine), everything is fine until I hit browse, which causes a screen to pop up that syas "The folder contents could not be displayed VFS error: Invlalid paramteres." and the following shows up on the command line:

I have a server in a data centre, which is supposed to have a 100Mbit line. Peak rates at the moment on my server are in the region of 20Mb, which should be easily handled. Is there anyway I can trace how much more bandwidth is available at any one time or if things are becoming sluggish on the server?

Most of my many Linux installs boot up to a memory use of 170-190 MB with no open or running programs. But with Ubuntu 9.10 it shows; 305-310 MB and the top RAM use item is the; compiz.real, which I think is a display desktop effects application. I have the nvidia video card driver installed, and that nvidia X-Server configuration tool. Also I can not find where that compiz options is at, ( the display options in system, preferances does not open, and says to use my video card tool ).

I was a user of openSUSE 10.3. I used to get a decent speed in BitTorrent (using KTorrent 2.2.1) there, since I had earlier used Windows and the speed wasn't as good, even in Windows 7. Recently, I installed openSUSE 11.2 and found that I wasn't getting the good speeds in KTorrent. The overall performance was a fraction of what I used to get in the older Linux installation.
I decided to verify whether my suspicions were justified by again reinstalling openSUSE 10.3. When I did this, I was again able to get the great performance I used to get always with openSUSE 10.3 running KTorrent 2.2.1 I don't know what causes this, but I know that this sad thing really has happened. A newer version is actually not worth it! I hope my voice reaches the openSUSE developers and such bad incidences don't occur anymore.

I have become a recent fan of linux and I want to install ubuntu on my acer aspire 5630 because vista runs terrible on it. Everything seems to work fine when I run it off the cd im just wondering if it will still work great when i actually install it. Is there any big difference between running the os off the cd compared to when you actually install it?

With all the talk about disk encryption for Apple devices, I wanted to ask about how full disk encryption compares between debian linux and mac OS X. Is the code for debian linux fully available for people to inspect for flaws or backdoors? Apparently although part of the encryption code is available for OS X the full code for Filevault 2 is not public. What are the advantages and disadvantages of each method of encryption for each operating system?

I've noticed since switching from Kubuntu 10.04 to openSUSE 11.3 on my laptop that the Adobe Flash plugin seems much more prone to crash and fullscreen video playback (e.g. Hulu) performs terribly. I can't figure out what's different between the distros. In both cases, I'm using a 64-bit OS, Firefox and KDE, and the proprietary NVIDIA driver. Anyone know what might be happening, or more importantly, how to improve Flash stability and performance on 64-bit openSUSE?

first of all im new to OpenSuse i have been using different distros since early 90's if theres one i havent tried i would be very surprised anyway im very picky when it comes to sound and picture maybe its the fact that im a developer and also art director anyhoo i got tired of my HTPC ( windows ) i thought linux has to be able to do it just as well i mean i only use it for movies and music but was surprised to see how video works in linux picture is somewhat ok compared to Windows but movement is another story even vsync off it looks like a old VHS tape when it should be DVD. Cam-panning is even worse. How is this and can it be fixed?

I notice that the NVIDIA GPU on my Dell XPS M1330 gets much hotter under Lucid than with Karmic (or Windows).While the temperature monitor in the "nvidia x server settings" showed between 50 - 60 degrees under Karmic I get readings above 70 degrees with Lucid and the fan is permanently on. I have no GPU intensive applications running.

I was wondering if torrents and torrent programs don't work as well in Linux compared to Windows.I have used them in the past but all of a sudden, nothing would work in my Kubuntu install. Absolutely nothing would start. I tried different configurations, settings, but nothing. I left it alone and rebooted and started up XP. I installed Azureus and I didn't do nothing else.I didn't even configure Azureus and left the router settings.I was able to start a download.I've used KTorrent (default) and Azureus before.

Debian lenny, old install (I've upgraded to lenny when it was just about to become the stable release), versus windows 7, fresh install.Comparing browsers speeds with numion.com/Stopwatch.html, I had results such as:Iceweasel (firefox) on linux: from 9.154 seconds to 21:860 seconds (the same webpage, reloaded)Firefox on windows: 4.32 seconds - and never much slower than thatThe fastest browser on linux was Opera, ranging from 8.562 to 5.503 secs to load the same page, but even internet explorer beat/match it with its timing of about five seconds.
I have not other browsers on windows; on linux there is aroraonqueror (KDE3), kazehakase, chrome, and dillo, besides text browsers. I didn't test on dillo; Kazehakase and chrome were the only ones which had nearly decent results, but still very bad, 11 to 13 seconds for chrome, and 21 for kazehakase. Konqueror just seemed to never finish to load the page, I gave up when it was still loading somethingfter nutes and 5 seconds.'ve emptied the cache every time I would test, and I was running almost only the browsers and not much else. Whatever comes by default on windows, and on linux, I was on openbox, with nothing much going on I guess, I think the most memory consuming processthe time, besides xorg and the browsers themselves, was dictd.
I've researched a little bit about, but not enough to make a list of possible things to change in order to improve the speed on linux. Most of the time there are people just agreeing that on windows the rendering is faster, and other people saying that with them is the opposite, with some minor variations like people saying that linux is faster for plain downloads while windows is faster for web browsing due to better graphics.
(by the way; I haven't installed any graphic card driver on windows, which is still running on 1024x768, while linux runs on 1280x1024, with the "nv" generic driver, without fancy options, not supported by my old card) The closest to a suggestion of possible solutions was someone saying tha compilation may affect performance, I guess it was both about kernel compilation, and the web browsers themselves.I'll google a bit more about how to "compile for speed", both kernels and programs (maybe the x server

i recently purchased my second laptop, primarily for linux. When i chose it, my main concern was battery life. Just to make a side note. When i say battery life, i mean how long the computer takes until the battery goes flat. Not how many years/ect it takes till the battery will no longer hold charge.
My new computer claims to be able to get 10 hours. Although it's a bit off, i get a satisfying little bit over 6 hours, from full charge. This is running Windows 7. I couldn't wait to put Linux on my new computer, i have, but it just isn't satisfying because i only get about 4 hours while running linux, tried three different distros, and all roughly the same.

We have a 32bit Gui application created using C++. We ported the application from Solaris to Linux. Issue we are facing is the size of the library and executable is very large in LINUX compared to Solaris. Red Hat Enterprise Linux 5.4 is the Linux version we using. Please find a sample dynamic library created. We would like to know the following behavior of LINUX is normal or not. Consider we created two files test1.cc and test2.cc. Both having a single line of code.

I have used Ubuntu and Linux Mint for quite some time now until I got a new machine. Some friends told me to try OpenSUSE because it has really been polished over the last few years.Install went smoothly got everything working properly except for my video card. My video card is an ATI HD4890 with sound support over HDMI. I had the sound working in Ubuntu using the non-oss ATI drivers. I was wondering if someone could please teach me how to install them again here on OpenSUSE 11.3. My screen fonts and colors also look terrible compared to Windows or Ubuntu.
Is there a way I can make it look better? I remember CCC (Catalyst Control Center for ATI) had two color formats (RGB and YCbCr). I had to set it to YCbCr because my screen is an HDTV and it looked much cleaner than RGB. Is there a way I can acheive similar results with OpenSUSE?

I have two ubuntu boxes. One is a 9.04 desktop edition and the other is a 9.10 server edition I am working on some code that needs to be highly tolerant of bad network connections. It sends transactions to a central database, but when the network is not available, it caches them locally to retry later.
I have the code working beautifully on my desktop box. but when I test it on this other box (the one running server edition) there is a HUGE DELAY every time it tries and fails to send a transaction to the database when the network is down.
I tested a little further, and I found that if i unplug my network cable and run ping somehost on the desktop, it fails instantly saying "ping: unknown host somehost" But if I unplug the cable on the server box and run the same ping command it lingers for about 40 seconds before the ping fails.
Does anybody have any idea why this might be happening? Is this a 9.04 vs 9.10 difference? Is this a desktop vs server difference? Is there some package I can install, or some config setting I can change that will make the server box insta-fail just like the desktop does?
