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

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... Scot P. Floess 27 Lake Royale Louisburg, NC 27549

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, Jerry

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? I'm a little

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 are using

Doing a kickstart install of Fedora 12 results in a non-bootable image. >From a virt-maanger instance, the error produced when trying to run the domU is: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup

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.

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

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." Then I have to

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 to put

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? cheers Sven

I am pleased to announce the official release of Virt SIG Xen packages for CentOS 7. To install: * Install centos-release-xen from centos-extras yum install centos-release-xen * Update to get the new kernel: yum update * Install the Xen packages from the centos-virt-xen repo: yum install xen There are also packages for libvirt 1.3.0 (which should be compatible with openstack) and

So first of all, if you've used the CBS before, please note the name change -- it's no longer virt6-testing, but virt6-xen-44-testing. Easiest way to install: rpm -ivh http://cbs.centos.org/repos/virt6-xen-44-testing/x86_64/os/Packages/centos-release-xen-7-7.el6.x86_64.rpm This will set up yum repositories for both the eventual release repositories (enabled by default), and the

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

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". Traceback (most recent call last): File "/usr/bin/pygrub",

Folks I'm about to set up a non-root user on a Centos=7 server that I control for a friend. It is in his home, so access is local. He's a refugee from the latest Windows 10 Upgrade. I'd like a suggestion as to which of the several possible graphical desktops to suggest to him and set up for him as his default. My aim is: - Allow him to try out Linux as an end-user - Let him
