I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried

When I query for installed package on the system, I get following result: # yum list installed openssl Loaded plugins: fastestmirror, tsflags, verify, versionlock Loading mirror speeds from cached hostfile Installed Packages openssl.x86_64 1.0.1e-16.el6_5.4 @updates/$releasever When I try to install already installed package (just playing with yum), I get following result: # yum install

I have CentOS 7 host. Two guests on bridge network setup by GUI and virt-manager. 1 CentOS 8 guest 1 Win 10 guest Both cannot access the host. They can other machines on the network. Guests can access the internet just not the host. I used virt-manager GUi to set up everything. Selected the eth0:macvtap and Bridge. I "desire" bridge network. If I select something else I get access to

Maybe my google-fu is failing me, but I have spent the past couple hours looking at how to add a vnet? Device to my KVM host running CentOS 6, and for the life of me I can't get this going. >From all my research if I want to add a device I should just do 'brctl addif br1 vnet14' if I want to add a vnet14 to bridge br1. When I do this, I get: # brctl addif br0 vnet14

Hi, I want to upgrade my libvirt version, in order to get a bugfix from upstream, see this BZ for details: https://bugzilla.redhat.com/show_bug.cgi?id=1084477 in short: libvirt does not handle qos correctly prior to version 0.10.2-33.el6 however, it is not (yet?) available in CentOS. The latest available package seems to be: libvirt-0.10.2-29.el6_5.7.x86_64 Please correct me if I'm wrong.

Tried that as well, but this has to be something that gets set at the OS level and loaded, as if you look at dmesg output, you can see all the vnet?? nodes as the OS comes online. So the question is, what is virt-install doing that creates the needed vnet interface that is part of the bridge. I really had to kill and reload the VM just to load a second interface.. --- Howard Leadmon

How do you decide what MAC address to use for that VM interface? As I just tried to change the MAC to some other value close, like I made '52:54:00:34:e1:21' into say '52:54:00:34:e1:32', and when I try and load it in, I get the following: error: XML error: Attempted double use of PCI Address '0:0:4.0' Here is one of my network entries: <interface

Can i assign static vnet* device for some guests?

Hello, I have see that my machine have an interface that named virbr0. I have no idea what is it and what it using for ? I am not configured any IP address for it but I see it had an IP address and see it listed in firewall config. Can anyone give me an explanation about this or point me to a document that describe it ? My machine running CentOS 5.2 and do not have internet connection from

Hi, I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following: eth0 Link encap:Ethernet

Hi All, I am facing an issue regarding communicating a value from outside to a Guest OS (linux, solaris and windows) launched on Xen Server. I did went through this thread, but It was not completely clear. http://lists.xensource.com/archives/html/xen-users/2006-07/msg00473.html My question is - Is there a way in Xen, through which I can communicate a value from outside to a Guest OS (linux,

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

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
