Re: [CentOS-virt] How to manually add a new interface to a bridge device?

2015-12-09 Thread Howard Leadmon
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.

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 K

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

2015-12-09 Thread Zoltan Frombach
The MAC address you gave is fine. I use random MAC addresses just like you did. Your PCI bus address also has to be unique within a given VM. I'm sorry, I forgot to mention that. Look at my configuration example I sent. These are emulated (virtual) network cards attached to the emulated (virtu

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

It looks like no XSA-142 patch, which is "libxl fails to honour readonly flag on disks with qemu-xen" has been applied to Xen4CentOS. I assume this was on purpose? If not, I can have someone try adding the original patch from http://xenbits.xen.org/xsa/advisory-142.html and some variant of the c
