[opensuse] Seasoned Linux user but new to openSUSE
Hello, I am testing openSUSE 12.2 KDE in a VM in Virtualbox on my host distribution PCLinuxOS. The VM specs for openSUSE: RAM 3584 MB, video maxed out at 128MB, virtual hard disk 16GB. According to the specs on one of the openSUSE sites this is more than enough to run the distribution properly. openSUSE runs painfully slow in this setup. I find that very strange because I also set up a guest install of PCLinuOS as a VM with the same VM specs and I setup Debian in a VM with the same specs. Those two both run as fast as the host. I am not running all of them at the same time. I run one at a time. I have plenty of hardware resources to run one at a time and very efficiently. That is why I don't understand it being slow. I can run windows 2000 in the VM and then run AutoDesk CAD software which is a major resource hog in that VM and it runs fast. A computer running CAD software needs the same heavy resources that a hardcore gamer runs to play their 3D games. I have discovered that all three Linux distributions have very different behavior when first setup such as the guest additions. openSUSE guest additions just worked without any installing or configuring required. PCLinuxOS required manual install and some simple configuration and Debian required a lot of things to be installed before the guest additions could be installed and then some complicated configuration before the guest additions worked. Setting the time, time zone and configuring NTP is very slow and the settings for the hardware clock on/off UTC keeps changing back to on UTC between boots. Is there something I can do to get openSUSE to stop changing that setting? Can't run it with UTC on in a VM because the VM uses the host software clock as the hardware clock for the VM. Also running the package manager to install or just do the updates it wants to do is very slow. Is there anything I can do to solve this? Like I said the other two distributions running in VMs run fast. I don't get why this one doesn't. I am sure this distribution will perform much better installed on real hardware and not in a VM environment. I could very easily start using this one a long side my other ones. I have some ideas where this one could be a better fit than the others. I convert MS windows users to Linux and I don't always set up the same distribution for everyone. I use three flavors now and this would be number 4. Thanks for any help getting this figured out.

Update ntp package, it is fixed in latest patch. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Our servers use a mirroring service and redirecter (mirrorbrain) which redirects incoming http requests for system updates and software packages to a mirror based on geographical proximity to your IP address. This includes the repository metadata that informs the package management stack of available updates and package versions. The mirror you are being redirected to may be slow. You can alleviate this to an extent by tweaking the repository metadata refresh interval in the following config file: /etc/zypp/zypp.conf The config option to uncomment and change is repo.refresh.delay = 10 By default this will be commented out and the default refresh interval is 10 minutes. You could set this to once per day e.g. repo.refresh.delay = 1440 Cheers the noo, Graham -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The first thing to would be to run 'top' in a terminal and find out if there is a busy process. Then openSUSE uses file indexers like tracker, which can tax the filesystem quite heavily after installation. I thing iotop would flag that. Then there is the desktop. If you are using effects, they tax the virtualized graphical system. You can check by temporarily running one of the lesser desktops.

Well, you should not run NTP on any guest system, it should run _only_ on the host. Then you use tools from the virtualization environment to keep both in sync. I use vmware myself, not virtualbox, so I don't know exactly how you do this in vbox. In the case of vmware, they have this issue properly documented on their site, so it is not just my opinion on "not use NTP". Then the other thing. You have to run "yast", select "date system and time", and then make sure that the tick box for "hardware clock set to utc" is off, ie, configure it for local time. 12.2 may complain and warn bitterly against this change: ignore it. There is a bugzilla reported about that issue. There were bugs related to this settings, so you are not finished yet :-) Edit "/etc/sysconfig/clock", you should have: HWCLOCK="--localtime" Then you should rm /etc/adjtime (there was a bug in 12.2 by which it was not created or was wrong) and force its recreationg by running hwclock --systohc --localtime but make sure by running "date" that the clock has the correct time before doing it. You may want to read this: https://forums.opensuse.org/blogs/jdmcdaniel3/what-utc-gmt-time-possible-iss... and also this: http://en.opensuse.org/SDB%3AConfiguring_the_clock Finally, for checking that the clock is running correctly, use these two commands in a terminal running as root: hwclock --debug date Please ignore what KDE clock says. There was also a bug affecting its timezone setting, but as I don't use kde I don't remember how to correct it.
Also running the package manager to install or just do the updates it wants to do is very slow. Is there anything I can do to solve this?
Dunno. Repository refresh, network performance, database update, busy cpu...
I am sure this distribution will perform much better installed on real hardware and not in a VM environment. I could very easily start using this one a long side my other ones. I have some ideas where this one could be a better fit than the others.
Now and then some people have issues with a slow system on real hardware, too. Difficult to diagnose. However, a virtual machine like yours would be reproducible.
Thanks for any help getting this figured out.
