Hey, I was originally asking questions on xen-users but no one seems to have any idea about this so I figured I''d try this list. I compiled Xen from source (3.2 testing) on an Intel machine running Fedora Core 8 and have discovered that my guest (Windows Vista) does not have a network connection. Looking at various online documentation and a machine that does work, I guessed that I

Hi everyone: I am new here I am using kvm and libvirt on my Dell server. Now i am trying to migrate one virtual machine from a physical server to another. However, I failed everytime.

Hi, I am trying to migrate a guest domain from one node to another. I've tried several options of the virsh migrate command, but in vain. It seems to be a networking issue. I wanted to make sure that my setup is correct and that I am not missing anything. I've issued the below command on the source node (n0): [user at n0 ~]$ virsh --connect qemu:///system migrate --verbose

There are some normal LAN clients behind the Linux firewall's GREEN interface, which can all access each other's shared services and also

Dear Linux Gurus I'm having problems with KVM and networking. My guest cannot use NAT through the host's connection. This is what I've done: I installed a new version of Centos 6.5 on the hardware. Starting with a Net-Install, I selected the Virtual Hosting, and later added "Desktop". I ran "yum update" with some reboots until nothing needed updating. The

Hi, I have a server running CentOS 5.5 with KVM capabilities. I need to migrate all the VMs to another server with the exact same hardware specs. The problem is it is running on individual harddisks, not shared storage. What is the best way to migrate to minimise downtime? Thanks!

Hi, I have two guest vm instance running CentOS 5 with ext3 partition. I will like to reduce 1 VM harddisk space and using the 'release' harddisk space to add onto my second VM. Basically I need to know how can I reduce and increase an ext3 partition in CentOS KVM. I did a search and basically i can do it by booting the VM using Knoppix and use Gparted to reduce and increase the

CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere. I want to keep the

Hello all, I am having issues getting my virtual network to work correctly. As of current, I have set up a virtual network with virt-manager, using the routed mode to forward network traffic. I have found guests can see/ping themselves, the host's virtual IP and the host's real IP, but nothing else. Guests fail to see any other device on the real network or the internet. My host is Arch

Hello all, Basically my problem is how can i access a virtual machine from local network. I am able to do so from the host PC put not from other PC's on the same network. here is my what i did so far (http://wiki.libvirt.org/page/Networking#NAT_forwarding_.28aka_.22virtual_networks.22.29) cat '/etc/libvirt/qemu/networks/default.xml' <network>

Situation: Running a simple UDP client/server program where the client on one domU on one computer sends echo packets to another domU on another computer, server sends echoes back. They do this on a specified port (will use any port between 5000-6000). This program works on non-Xen machines in various environments, Linux and Solaris. Program just hangs on the domUs. I believe I need help with

I've run into a problem on my KVM host where a single guest will be unreachable to other guests on the same host. This host has 2 bridged devices and guests assigned to each have the same issue. I've noticed that when I can't reach the problematic guest, the ARP entry for that system is incorrect. This issue seems to only be a problem about 75% of the time when making connections

Running CentOS 6 I have noticed that Libvirt will automatically configure IPtables once a VM is using the built in NAT , or "default" network. How do I modify the IPtable rules without breaking libvirt's ability to configure these rules? This is the firewall settings on a fresh install with no VMs using virbr0... -------------------------- Table: filter Chain INPUT (policy ACCEPT)

I just wrote this to assist some Red Hat folks understanding what libvirt does with iptables, and thought it is useful info for the whole libvirt community. When I have time I'll adjust this content so that it can fit into the website in relevant pages/places.

Thanks for the reply! output: net.ipv4.ip_forward = 1 What do you mean "The out:any and" Anywhere else I can look as to why the connection isn't going? Do I need some kind of listener at that port on the host? I'm not even seeing the packet count on the prerouting chain increase when the connection attempts are made.
