I would stop the VM, edit its definition file (that's an XML file) and then start it up. But be careful: After you edit the XML file, you need to execute a command so KVM re-reads that file. I forgot that command, but you can look it up on Google. On Dec 9, 2015 7:52 AM, "Howard Leadmon" <howard at leadmon.net> wrote: > > > Maybe my google-fu is failing me, but I have

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

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

You most definitely do not need to destroy and re-create a VM just to add a 2nd network interface. I don't think those vnet interfaces got created by the host OS. I believe those are created by KVM (or libvirt) when you start a VM. I could be wrong though. But I just checked on my CentOS 6 KVM host machine and I see as many vnet interfaces as many VMs are currently running (or if one VM

BTW, adding a 2nd virtual nic to a guest can also be done with command line tools (I just googled this for you) : https://kashyapc.fedorapeople.org/virt/add-network-card-in-guest.txt ( It came up as 1st result when I searched for: virsh add network interface to existing guest ) But if you look at the bottom of this guide, they also mention that if something goes wrong, they resort to using

Hi all, I've got a problem with nwfilters/iptables. For one of my guest's interfaces, I have established the following filter: --8<---------------cut here---------------start------------->8--- <filter name='p-mgmt' chain='root'> <uuid>94fdd15b-b380-ba8c-6685-91206829adc7</uuid> <filterref filter='clean-traffic'/> <rule

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

Any help here? I have included all of the output of the suggested diags that Thomas said I should run, but I admit that I'm not sure what I'm looking for, as I'm not familiar with RPC functionality on Linux. Something is not working with RPC on my Samba 4.0.3 server. (FWIW, it doesn't work with IPTables stopped either.) > On Mon, Feb 25, 2013 at 2:21 PM, Mike Stroven wrote:

Hello, it seems I cannot use: $ ssh -J root at 2a01:4f8:1c1e:528d::1 root at west-coast Invalid -J argument (The west-coast is stored on the jump host in between in /etc/hosts.) $ ssh -J root at 167.235.141.44 root at west-coast Works as expected. Also $ ssh root at 2a01:4f8:1c1e:528d::1 does work as expected. I do have native IPv6. This is on Debian 12 Bookworm: $ ssh -V OpenSSH_9.2p1

Hi list! I have a CentOS 7 server running dovecot with GSSAPI auth enabled. Version 2.3.10 was working fine but after the upgrade to 2.3.11 it stopped working. On thing I see on the logs is that the user field comes up empty when compared to the 2.3.10. Example: 2.3.10: Sep 14 13:39:20 mail.r3pek.org dovecot[10189]: imap-login: Login: user=<r3pek at r3pek.org>, method=GSSAPI, rip=xxxx,

To Whom It May Concern, I tried emailing the ostensible mailing list owner, at both addresses noted, and got no response. Maybe somebody here knows how to alert whomever must know about this.

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

Hi, I''m new to XEN and have the following Problem: If I shutdown my domU the network of the dom0 leaks. A ping from another server to my xen dom0 shows a Packetloss > 80%. Then if I restart the domU after some seconds the ping show a loss from 0%. I retryed that 3 times but it is really hard to go to the dom0 via ssh and recreate the domU if the packetloss is that high. I used google
