OpenSUSE Install :: 11.3 - Running KVM With Hugepages Support
Nov 19, 2010
I want to experiment with hugepages support in KVM. I have added
<memoryBacking>
<hugepages/>
</memoryBacking>
to my domain xml.
Also I create the directory /hugepages and mounted it using
mount -t hugetlbfs hugetlbfs /hugepages/
and created huge pages using
echo 4096 > /proc/sys/vm/nr_hugepages
Now, when starting the domain from virt-manager, I get the message:
libvirtError: internal error hugetlbfs filesystem is not mounted
What is the recommended way to setup hugepages in opensuse 11.3?

I have GParted installed, running openSUSE 11.3 with GNOME. When running GParted, it always grayed out most file system actions, supporting only hfs fully. This made no sense, as I had all the required packages installed for other file system support. However, I recently figured out how to get it to work. Using the installed menu button doesn't work, running "gnomesu /usr/sbin/gparted" doesn't work; to get it to work, I have to open up a terminal, type "su -" to log in as root, and then run gparted. The menu button and gnomesu both prompt for a password, so it should be running as root, but launching it through the root terminal is the only way to actually get it to work. Is one root different from another?

I am learning about linux memory and hugepages, and know that hugepages basically is just memory that manages memory. I thought I'd experiment with the subject, and wrote a very small C program [URL] that basically just eats 20 GB of memory. The idea was that I would use this small C program to see how big the page table would get when handling large areas of memory when I'm not using hugepages. After running the program on my RHEL 5 server I was expecting the PageTable to be huge, but found that it was only about 43 MB. The page size on my RHEL box i 4 kB. Why I'm not getting the major PageTable size issue I was expecting?

I was thinking of trying out the UEFI support that HP has in my laptop BIOS in the next few days. My reasons is that I get a custom boot logo... and (hopefully) a better boot-speed. What is the current state of affairs with the openSuSE UEFI/EFI install support on a empty hdd for x86_64 does anyone know? (badly worded I apologize) This may seem naive but I have struggled to answer this with most posts being about Mac's for obvious reasons.
Specifically, Do I have to have any custom knowledge on formatting the HDD with a GPT partitions or does the installer do this for you? Secondly, How well does the UEFI bootloader tie in with the config tools in YaST2? (I would like to have UEFI but if it turns into some headache in setting up the boot area by hand each time the kernel updates I will forget it.) I can safely say this will be a machine with only openSuSE installed as an OS, no need for any others or any dual-boot problems. This isn't overly urgent and I will dedicate (at least) a whole weekend to tweaking once I buy a new disk and install openSuSE on it. If nobody knows then I will dive in head first and report how I find it and any problems (and severity).

i try to set-up my apache to support SSL.
the SSL conf file under '/etc/apache2/vhosts.d/mySSL.conf' will run if i restart (/etc/init.d/apache2 restart) apache through the terminal.
but if i restart apache/HTTP Server in YaST, my conf file (/etc/apache2/vhosts.d/mySSL.conf) will be deleted and the SSL wont work.
tell me what is happening to the system? coz i use yast primarily than the terminal.

In OpenSuse 11.2 it was possible to pass the ip configuration on the kernel command line and the kernel would configure the interface (eth0 in my case) properly. The ifcfg-eth0 needed to be configured as 'static' and 'auto' with the other parameters absent. The kernel arg would look like: ip=<client-ip>:<server-ip>:<gw-ip>:etc:etc
This no longer works or works differently in OpenSuse 11.3, despite the fact that ip_pnp seems to be compiled into the kernel. Is there some way to enable this in 11.3? I just want to do basic static routing with the parameters passed directly to the kernel instead of hard-coded in the ifcfg-eth0.
p.s. in 11.3 when I try to do the ip_pnp method the eth0 does come up but none of the routing is correct. There is no default gateway and no ip is assigned even though I am passing the kernel args properly.

I have been trying to upgrade (ended up trashing and reinstalling) from 11.1 to 11.2. I selected French language with UK keyboard. This option seems in the end to just default to the French keyboad. Reinstalled with UK lang and UK keyboad which is acceptable to me but I then find a big problem. How do I set the compose key so I can enter accented characters etc. (� � � ...) Prior to 11.2 this was some with SAX but SAX support for keyboards appears to have been removed and I believe should be provided by KDE, Gnome, etc.
Does anyone know how to define the compose key in 11.2? I have searched google and the suse forums but found nothing other than something in German that I did not understand. While I could buy a French or perhaps better a Swiss keyboard for the tower this is not a real option for the laptop and on-screen keyboards are useless.

telling me if this behavior of my openSuSE 11.2 installation is normal? I use a 64-Bit openSuSE 11.2 with kernel 2.6.31.x with root partition ext4. After adding and updating from repository kernel:/HEAD/etc to 2.6.34-rc4 I can not boot anymore due to a lack of module ext4. I thought today ext4 is stable and fix built-in in the actual kernel releases, isn't it? The error message at boot time: FATAL: Module ext4 not found. Which is right because in /lib/modules/<kernelversion>/kernel/ there is NO 'fs' subfolder. Isn't the kernel:/HEAD/ repository the official update path to get a newer major kernel? (besides openSuSE's Updates for security reasons) Do you know how I can fix it without self-compiling?

I am going to install a computer for multi-language support for English and the Korean Hangul written language. I would like to configure the input from the keyboard to switch from English to Korean. I have keyboard with English and Korean and I would like to configure one of the keyboard buttons to switch the input language similar to how Microsoft multi-language support works. What applications and configuration changes are necessary to implement this.

I am impressed with 11.4 and am happy that for the first time ever I don't need to install a kernel patch to support my on-board nVidia graphics. However, the on-board sound no longer works now. I don't know how to set it up in phonon. My device number 0 in phonon is MCP72XE/MCP72P/MCP78U/MCP78S high definition audio, and I assume this is my nVidia on-board sound card. The driver information states snd-hda-intel.
How can I check what is wrong with it? It did work fine on 11.2 right up to the 11.4 installation. I do get system sounds (like the start-up and shut-down sounds), but nothing from any application, e.g., firefox playing a video. Based on the advice from another thread I tried: speaker-test -c2 -l5 -twav This does not produce any sound, but gives the following information: speaker-test 1.0.24.2
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)

I put together a step-by-step guide of how I installed openSUSE 11.1 on my ASUS Eee PC Seashell 1005HA Netbook. I planned on going back and re-installing using my own guide to check for mistakes, etc. but I never seem to get around to it, so I'll just post what I have and let you guys comment if you run into issues. Side notes: This guide assumes you want to wipe out Windows XP and run only openSUSE. Sorry, I'm a Gates hater.
I still haven't figured out how to configure the function keys support for volume controls and wireless. I'm hoping the "eeepc kernel module" mentioned by malcolmlewis here: Suse on my Asus 1005HA - openSUSE Forums will do the trick.

I'm running Fedora 15/2.6.38.6-27.fc15.x86_64. When I run <code>qemu</code> I'm getting "Could not initialize KVM, will disable KVM support" I know my CPU supports hardware virtualization, it has the vmx flag (grep vmx /proc/cpuinfo). I've checked that:
1. kvm and kvm_intel modules are loaded
2. /dev/kvm exists.
3. I'm in the kvm group, so I can access /dev/kvm..
Why KVM doesn't work?

I am completely new to OpenSuse and just installed it. However, I wanted things encrypted for work and chose LVM2 with password encryption upon installation.However, I didn't change any of the values.Now I see that my home partition is only about 30 Go and I cannot mount the oter 300GB that sit on another partition. When I try to mount it through nautilus I have to enter my password and then get :Unable to mount 307 GB LVM2 Physical Volume

I'm running Slack 13.1 64 bit. I'd like to try running multi for 32 bit support so I can run a 32 bit version of firefox using the 32 bit flash plugin. Here's what I did: - followed Alien Bob's Wiki and download and installed all the *txz files. - installed a bunch of required libraries following the instructions on the Wiki - installed the 32 bit 10.1 version of the flash player plugin in $HOME/.mozilla/plugins/ - started the 32 bit 3.6.3 version of firefox; it seems to work fine. - go to about plugins and verify that Shockwave Flash (libflashplayer.so) is version 10.1 r53 and it is enabled. - run "ldd libflashplayer.so" and verified that all libraries are found. - run "ldd /usr/lib/firefox-3.6.3/firefox-bin" and verified all libraries are found. - go to [URL]... and click on "test your adobe flash player installation" I will get this error: Adobe Flash Player error: could not load cURL library - I verified (repeatedly) that I do have what I think is the correct package. How can I fix (or start debugging) this error?

After upgrade of 11.1 to 11.2 I noticed that none of services that was started in 11.1 at boot are starting now in 11.2. I check run-level of services with
Code:
chkconfig --list
When I start services manually everything is OK, but on restart they do not starting. Another weired thing is that my SuSEfirewall2 is filtering everything on input, nevertheless my previous configuration is still there, but ports are closed.

I just got an android phone that I will want to interface with my linux box, which is currently behind a time warner cable modem. In the morning when I'm groggy, and my computer is off, I want to be able to kick the power button on, leave for work, and have it e-mail me the ip address I get from time warner, so I can check it on my phone.
I don't have the script written or anything yet, all I'm asking about here is how I would go about getting the script to run once I have it -- I can boot to a user using an automatic login and probably get away with it but that seems to be poor practice.
I'm really a stranger to the world of customizing a bootup.
Leaving the computer on all the time is a bad option even though my electric is included in rent, I live in a studio and I don't like the noise, and the environment and all. And manually doing mindless, automatic work is not the reason I have computer.

Windows has lots of space available (especially the "d" partition which I use for storing stuff in like music and video) but I do not know how to "claim" that partition for for Suse.

I was messing around couple linux distros and a desktop earlier today. When I booted from the Ubuntu disk, it seemed to take like 2-5 minutes on each screen. So was basically taking like 10 minutes before I even got to the disk's menu. When i booted the machine off of openSUSE 11.2 disk it booted nice and fast, then installed without a hitch.When i put the Ubuntu disk into my laptop it booted fast and fine there.I'm just curious if anyone has any ideas why that desktop would seem to disagree with a bootable Ubuntu disk like that. Those things are obviously designed to work with near anything. It's a standard IDE CD-ROM, 7600GT, IDE hard drive, all pretty standard stuff.
