I need to know, if this is possible and will really appriciate if someone can provide me pointer in this direction. Thanks a lot. R.

No i can start qemu but no network I have a bridge br0 with ta0 on it My start line qemu debian.5-0.x86.20100901.qcow --curses -net nic -net tap,ifname=tap0,script=no

Hello, I successfully set up a tunnel with tinc using the tun interface. however I need a tap device, because I need to run the OLSR routing protocol on the tunnel and if I use the tun mode OLSR will just skip the interface. (It is a well known thing, I had this issue before also when using OpenVPN in the past). The problem is that I cannot make tinc use a tap device. I created the tap0

Hi, I'm trying to migrate a VM from one libvirt 0.7.6-1 (qemu-kvm 0.11.1+dfsg-1) to another libvirt 0.7.6-2 (qemu-kvm 0.11.1+dfsg-1) connected with SSH , i have followed pre requite (same shared, same path, same network conf ...) . But when i migrate , i have following error : operation failed: /migration to 'tcp:x.x.x.x:49157' failed: migration failed DETAIL : Unable to migrate

Hi, I want to migrate from vmware to KVM. Therefore I have installed debian stable (lenny) and create two virtual machines (KVM). Both (XP as well as Vista) running fine. After upgrading to debian testing (sqeeze) both XP-guest as well as Vista-guest didn't start anymore. Both are failing during preparation, probably because of a network-problem. I will give XP as an example: cat

Hello, I thinking about using PCI passthrough to dedicated a domU as firewall. I understand PCI passthrough concept. When done, my domU will see network card and the dom0 won''t any more. So I''ll be able to filter all trafic from outside, since it will go through network domU. Then, how will I be able to connect other domU (and maybe dom0) to the network domU ? In a normal way,

Dear list, I have moved my HVMs from xen to kvm and it worked well except some problems using virsh.

Hi guys, I hope you can help me on this issue with kvm/libvirt: using this command to install a kvm virtual machine: virt-install --connect qemu:///system \ --name p3k0401 \ --ram 2048 \ --file //dev/VolGroup01/p3k0401logvol \ --accelerate \ -s 10 \ --nographics \ --hvm \ --location='http://10.1.4.80' I get: Starting install...

Sorry if this off-topic but I have a qemu related question I was going to send to the qemu users mailing list but that list appears to have vanished. I thought this community might have some insight. I am interested in controlling VM access to different tap devices so I want to have different qemu processes bound to different tun devices. I've created new tun devices (eg. /dev/net/tun_low)

Hey all, I''m trying to setup roadwarrior connection to my internal network. So I''ve setup openvpn to create a tap0 connection and also have bridged the eth1 (leads to my internal computers 192.168.2.10-30 and tap0 which is the VPN connection. On my shorewall setup I have br0 maped to zone loc and eth0 to be my internet and I have masqing on my br0 to get my internal computers

Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Greetings, I've setup an vm with openwrt in it, defined a isolated lan between the vm and the host and booted the vm up. I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest. I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see: dagg@NCC-5001D ~ $ dhcpcd vnet0 DUID

Hello: I have a host running two KVM guests. The guests use br0 and each has a static IP address. I am trying to figure out if there is a way to use snmpd on the host to measure the traffic usage of the guests. I do not want to require anything running on the guests since I do not control them. Looking at netstat -in on the host, I see this info: Kernel Interface table Iface MTU Met
