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.

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, 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

Hi, I would like to mount a remote windows disk as samba share drive but unable to do so on my host node. I tried it on my instances and it works so i am suspecting that perhaps firewall could be blocking it. Right now i see that the iptables for the host node with KVM installed : iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp --

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

Hello listmates, It's been a few years since I've set up a router... and for some reason I seem to be getting hung up on this one. Does anybody have a sample iptables config file that would incorporate NAT and forwarding for a simple router? Thanks. Boris.

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

Hi, Is there a way to restrict port forwarding on the server? I want only port 8080 on the server to be available to clients. Example when i give this command clients should be able to connect: ssh -L 30300:localhost:8080 .... When i give this for example clients should not be able to connect: ssh -L 30300:localhost:4040 .... I tried this option in config file of server: PermitOpen

Hello list, I wish to report a problem with openvpn tunnels. Synopsis: Despite adding policies to the shorewall policy file, I have to add extra rules to allow the UDP port 5000 packets to get through. I have used no particular setup guide. I believe this problem goes away with shorewall 2.0.9, as I have implemented openvpn with that version on a different machine, and I see no UDP:5000 packet

Hi all, I have a CentOS 5.4 server-only installation, i.e. no X installed, and for some odd reason /etc/resolve.conf gets overwritten by NetworkManager on a constant basis. I haven't been able to track down how often, but I think it's on the hour, or something. This is the conents of the file right now: # Generated by NetworkManager # No nameservers found; try putting DNS servers into

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

Hi, after migrating to shorewall firewall from my own iptables rule set (to utilise freeswan vpn tunnels) I have successfully configured a 3 interface firewall with net2net vpn tunnels, with the help of the shorewall documentation. However I cannot seem to configure my final step which is to masq another subnet attached to my LAN (LANB, via Cisco 1603 router) to get internet access via the

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.

hi, first of all i want to thank all the developers of Samba for that wonder ful piece of software. Now to my problem.
