similar to: libvirt ignores ip setting when creating a xen domU?

Hi,  I''m currently stuck with creating VM which cannot boot with disk using blktap2 driver. I''ve been searching nearly a whole week and I couldn''t get a answer. When creating vm with blktap2, it keep shows a error:   libxl: debug: libxl_device.c:200:disk_try_backend: Disk vdev=xvda, backend tap unsuitable because blktap not available.  VM configuration (XML):

I want to get couple of DomUs running with Xen. I installed Xen 4.1.5 from source on a Fedora 17 Dom0. I did some reading on configuring DomUs using xl/xm and cfg files. http://www.fclose.com/b/linux/2544/setting-up-lvm-backed-xen-domu/ http://www.fclose.com/w/Setting_Up_Xen_DomU_on_Fedora:_Unmodified_Fedora_on_Top_of_Xenified_Fedora_Xen_Dom0%23Install_Fedora_12_Linux_via_Internet So basically I

Hi all, my dom0 is centos5.2 and domU paravirtualized is centos5.1 I can play sound on dom0 but not in domU (name: gasphar), moreover I use wifi as my inet connection and on installing domU cento5.1, I used virt-manager. I know that libvirtd made virbr0 and when changing to xenbr0, I cannot connect to internet but ssh to dom0 is fine! so how do I enable sound device on domU and changing to

Hello all, I''m in the process of installing my first Xen server. I have a dom0 installed (CentOS 5) with public & private IPs. I created a domU (RHEL 4). I left the networking setup at defaults, so I believe it''s using bridging; I have a virbr0 device in dom0 with an private IP on a new subnet, and domU has an IP on that private subnet. From the domU, I can ping dom0,

Hello, I'm looking for an example configuration for a PVHVM domU that works with 4.3.1. The one at http://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers causes 3 warnings and some errors: WARNING: ignoring "kernel" directive for HVM guest. Use "firmware_override" instead if you really want a non-default firmware WARNING: ignoring device_model directive. WARNING: Use

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>

Hi, In my office I have an HP Proliant server running CentOS 7. It's a minimal install without GUI. The machine has two network interface cards, and for now it's acting as gateway/firewall, and it's running ntpd, Dnsmasq and Rsnapshot. I'd like this machine to also be a KVM virtualization host, so I installed qemu-kvm and libvirt. The interface facing the LAN is enp3s0, so I

Hey folks, I created a DomU, installed Linux, and then realized I''d only given it 1 NIC so brought it down to edit the cfg file to give it another NIC. Originally I just had : vif = [''''] And so I guess the defaults worked for the 1 NIC. So I changed it to : vif =

Greetings, I have two vms, one is a router and the other one is a client, for some reason, the client vm is unable get ip via dhcp from the router vm. here are outputs: vm1.xml: <interface type='bridge'> <mac address='52:54:00:54:78:be'/> <source bridge='virbr0'/> <model type='virtio'/> <address

Hello, After saving and restoring a DomU (teste on the same server), doing a reboot to the newly restored domU will cause it to crash. This happens on PV and PVHVM domUs. I am using qemu upstream for the HVM guests, but I don''t really think it matters as long as PV guests behave the same. I want to confirm this if possible, before submitting a bug report and more details. I am using

Greetings, I have problem using Dom0 as NFS(v4)-server and DomU as client. When ever the client actually tries to copy data to nfs-server the virtual network (bridge) between the two hosts completely freezes and stops working. After this of course the client hangs waiting nfs-server to answer and server continues to try to contact nfslock daemon on the client. Dom0 is still accessible from

I''ve been trying to have all spice features working on xen domUs since the end of 2011. Basic functions were already working. Adding qemu parameters manually for vdagent and usbredirection was and is also working (I made the patches to support them directly on xl). Qxl was never working: one bug on xen and one on qemu about qxl are fixed, the other xen bug found months ago on the

This is fresh install of CentOS v6 and Xen v4.1 on a new Dell server following the tutorial posted at: http://wiki.xensource.com/xenwiki/RHEL6Xen4Tutorial Every thing went just fine, yet virbr0 won''t work and when I run brctl show I get the following error message: [root@pe1950 ~]# brctl show bridge name bridge id STP enabled interfaces virbr0

I need some help in understanding libvirt's virtual networking. I have configured bridged networking (shared physical device) on libvirt+KVM system which is working fine. Also, I am using default NAT network on with virbr0 bridge device and virbr0-nic. I would like to get better understanding on virbr0-nic works in this virtual network configuration. I understand that traffic from virbr0
