Question - Xen host, DHCPD and guest VMs
I have a question about a Xen host that runs dhcpd and installing
guest/running guest VMs on that host (that use DHCP)...
On other hosts or hosts running VMs, they are absolutely able to get DHCP
addresses no trouble... However, the fun begins when the machine I run
dhcpd on is also hosting VMs. I can see in /var/log/messages the request
and ack from dhcpd but the guest VMs never hear it.

xm mem-set on an F11 xen guest
I just tried to change the memory for my F11 xen guest from 512 to 1024.
After executing:
xm mem-set workstation 1024
xm list shows the memory still being 512. Anyone else see this behavior
before? I tried other values as well - but the memory is still what it
was when I created the VM...
I'm running CentOS 5.4 on an i386...

Silly question about KVM
I was wondering, if I do not have hardware that natively supports full
virtualization...and I choose to use KVM, will my VMs be running in some
form of chip emulation (and therefore terribly slow). To date, I've been
using Xen and am very comfortable with it. I have some fears that later
whenever Xen is dropped - I'll have to consider KVM.
Also, will Xen be carried forward should

Question about aspell, alpine and a Xen guest
I have some weird behavior I can't explain... I've noticed this behavior
since CentOS 5.2 (version I started running) through 5.4...
I am running a Xen host/VM. On my guest VM, I use Alpine as my email
client and Aspell as the spell-check... For whatever reason, when Aspell
is kicked off - there appears to be what I'd call a prolonged pause before
Aspell does its job. Should I

Shutdown/poweroff does not power off machine
I've got a Dell Optiplex GX240 I am running CentOS 5.4
(kernel 2.6.18-164.9.1.el5.centos.plus)... When I had Fedora 11 and 12 on
it, I could issue a poweroff command and the machine would power itself off.
However, under CentOS it doesn't turn the machine off whatsoever. When it
completes, the machine is still running with a message of "system halted."

Has anyone gotten Fedora 12 running as a Xen guest?
I am running CentOS 5.4 (both i386 and x86_64 - different physical
machines)... I've been able to get Fedora 11 running as a Xen guest - no
trouble. However, I have had no luck with Fedora 12. My kickstart file
lists /boot as ext3 - but for whatever reason Fedora 12 insists on making
/boot ext4.
I do have a bare metal machine running Fedora 12, so I thought "let me try

Silly question x64 vs i386
I have a really silly question... but just want to ask...
I have one box on my home network that is x86_64 capable... My other
boxes are all i386. As this x86_64 machine can, at most, house 4 GB of
RAM (currently only has 1 GB) - is there any advantage to my running
x86_64 on that machine instead of i386... Long story as to why I am
asking - but before I go off and moveit down to i386 -

question on virtual desktops
centos has the 4 virtual desktops by default.
if I have a terminal window open in desktop 1
is there a command I can execute (type in) to switch to desktop 2?
The mouse will not be attached at this point and I want to switch views
using a command line. How do I do that?
Thanks,

subversion 1.6.9 and sqlite 3.6.22
I'm in the process of setting up subversion and since the version
packages with C5 is, shall we say, showing its age, I've built an
updated version. In order to do that I had to upgrade sqlite from the
default 3.3.6 (which the current subversion will not build with) and I
went with 3.6.22. Has anyone else had any experience with whether or not
that breaks anything?

FreeNX : forward audio from server to client ?
Hi,
I setup a FreeNX server with a GNOME desktop, and I can access it from a
client with the NoMachine client. Everything is running fine, and now I
only have two problems left : audio and printing forwarding. I'll follow
the "only-slay-one-dragon-at-a-time" rule and take care of audio first.
Did anyone manage to forward sound with FreeNX ? Here, server and client

Yes, that's because the CBS is is not meant to be for production use,
but only for building and testing. This is for two reasons:
1. The CBS itself is not mirrored, nor provisioned for

Garbled screen after RAM Scrub on boot
Francis,
I just rebooted my Precision 470 and watched...nothing :(
I see the boot menu, and then everything goes blank - as in just a
blinking cursor until I get the login prompt.
No idea what it's doing - but I don't even see the scrubbing free memory
output...

Has anyone been able to start a Fedora 16 VM in Xen PV?
All,
I've had a heck of a time getting Fedora 16 to run as a guest VM under
CentOS 5.7 host as a paravirtualized Xen guest. I believe the issue has
something to do with Fedora 16 using grub2...
When I attempt to start the VM (via xm create), I get this error:
Using config file "/etc/xen/fedora-workstation".

OT: programming language for morons (newbie friendly language in Open Source world)
Hi folks
I have more than 12 years experience with UNIX system administration,
but I am too stupid for programming. My only programming experience is
shell scripting. I tried to learn Java, but don't understand it
because it is too complicated for my limited brainpower.
What programming language should I learn?
A friend said that C-Sharp (Mono) is very simple. Is this true?

Having trouble starting more than 8 Xen guests
All,
I've spent quite a few hours trying to figure this out to no avail... I
have two machines and the result is the same on both. Additionally,
each machine does not support full hardware virtualization...
I am able to create 8 VMs. When attempting to create ninth VM, I get the following

Desktop for newbies
My vote is still for KDE
It's got a similar feel to Windows before it went pear shaped at Win8.
It's fairly easy to use.
