dear All, I'm facing this routing problem, the setup is actualy part of ltsp, but I think this problem is Centos-specific. The server is a Dell Poweredge R210. The install is standard 6.4, updated. I have one nic facing the public internet: vi /etc/sysconfig/network-scripts/ifcfg-em1 DEVICE=em1 BOOTPROTO=none HWADDR=d4:ae:52:c1:28:2b NM_CONTROLLED=no ONBOOT=yes TYPE=Ethernet

I normally try not to ask questions until I have done as much research as possible, and again, this is the case... Just after I thought I had my RH5 samba/nis server working fine, I come across the inability to update nis passwords. >From the server as root: passwd guest1 Changing password for user guest1. New UNIX password: Retype new UNIX password: NIS password could not be changed.

Hi Xen-users, I am trying to boot of my fist guest domain. The below attached message was thrown on the screen. I am not quite sure that the below information is sufficient to root cause the issue.

Here's the problem. We perform full tar backups of our CentOS 4/5 machines in real-time at regular intervals. And when a disaster happens, we are able to restore those backups onto virgin filesystems, make the /dev/null, /dev/zero and /dev/console devices .. and boot the machine. This has worked well on standalone systems, and also on Xen 3.0.3 guests on CentOS 4.4 machines, where each guest

Hi there, I am using libvirt with lxc to create fedora 16 & 18 containers on fedora 18 host. first I did the setup with libvirt 1.0.3 and everything worked fine, then after upgrading to libvirt 1.0.4, I could not create character device on the guests : Test on the guest1 : # ls -l /dev total 0 lrwxrwxrwx. 1 root root 10 Apr 17 21:18 console -> /dev/pts/0 lrwxrwxrwx. 1 root root 11

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

Hello, As part of my project for my MSc, I am looking for a solution to implement nested virtual machines. My current scenario is: - I have a server with AMD Phenom II X6 1100T and 8GB RAM - virtualization enabled at BIOS. - I have installed 64bit CentOS-5.6 with Xen enabled (let''s call it as base1). - On top of base1 I have also installed 64bit CentOS-5.6 (guest1) with Xen enabled and

Hi guys, I''ve seen this post regarding "lvm resize" and this contains all the information I need to resize a disk inside domU : http://lists.xensource.com/archives/html/xen-users/2006-11/msg00019.html >From this post: "With this I can extend the LVs in the Dom0, and either shutdown the DomU and resize2fs from Dom0 or even (tested on test VMs and low-use

Gang, ???? I run several KVM host machines.? Due to updates, maintenance, and unexpected reboots sometime host machines are restarted.? I can easily envision a scenario where HostX needs some critical packages updated or is acting up.? I migrate guest0, guest1, guest2 etc. from HostX to HostY.? Then, in either a planned (i.e. scheduled maintenance) or unplanned (i.e. unplanned reboot) event

HI all, Is it possible to install a virtual guest (FreeBSD and OpenBSD mainly) from kvm host's console? I have tried to do some search about this but I haven't found anything about it. My idea is to launch "virsh start guest1" and inmediately "virsh console guest1", but it doesn't works until serial console is configured inside guest .... Any tip? Thanks.

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the

Greetings - I am going through some testing steps to expand a logical volume and the corresponding filesystem on a KVM guest and have run across a deficiency in my knowledge. I spent the afternoon yesterday googling for answers, but had have come up blank still. What I am trying to do is resize the file system to use the additional disk space that I added to the logical volume that the

Hi all, Someone played with kickstart bonding with centos 6.4 ? CentOS 6.4, as upstream now support ifcae bonding in kickstart network section. I've an issue with configuring a second bonding iface in kicstart on CentOS 6.4. The first bonding (bond0) works as espected but the second is not configured during installation.

Hi Folks: I am getting a "No driver found" dialogue when I try to build a guest using virt-install using a kickstart file. I am stuck. I am not sure how to fix or even debug this problem. Can anyone suggest a way forward? Here are the commands that I am using: $ # ================================================================ $ # Create the volume $ #

Hi Rich, We just talked about a new tool virt-diff which can diff files between two guest, suggested by Kamezawa Hiroyuki <kamezawa.hiroyu at jp.fujitsu.com> things like below, # virt-diff -Nru --guest=Guest0 --guest=Guest1 /etc/hosts Any thought about this? Another question, what do you think about implement iptables, firewall, yum, rpm, etc into libguestfs? Thanks, Wanlong Gao

Starting back in RHEL/Cent 5 I found that the only way to make sure your interface enumeration was consistent after install with what you had during install was to create a udev rules file using the mac addresses as the key. It is easy to run a short script in postinstall to create it based on how anaconda has seen them. In order for this to work on Cent 6 you have to set biosdevname=0

I had a major HD failure and need to rebuild my host server and the virtual servers that resided on it. I am moving from CentOS 5.6 to CentOS 6.3. I am using the same configuration, as best as I can tell, that was working only hours ago on 5.6 but does not work on 6.3. My guest server can see network traffic on the bridged network device but I cannot seem to interact with it. Iptables turned
