Re: Need information
Hi, in bridge mode all the guests and hosts should be in the same subnet always ?

Changing dnsmasq DNS settings for virtual machines
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, maybe this is an old fart, but I cant get it to work. I am running libvirt on a laptop, where a dnsmasq is already running to delegate dns info for my local (not-public) network. My resolv.conf (on the host) lists the system-dnsmasq as first server. I had to set the listen-adress for the system-dnsmasq to 127.0.0.1 and set

How can I set the advertised value of MTU for virbr0 interface?
Hi all, I want to set the advertised value of MTU for virbr0 interface on a Fedora 21 host to 1454 to accommodate the installation of new VMs for testing purposes. The aforementioned host is an OpenStack VM actually, which explains the need for a lower than 1500 MTU. I noticed Pieter Hollants' patch to set dhcp-option=<number>,"<value>" for an interface, but

Re: Virtual Bridge "Network" for Sandbox
Thanks Laine, I will take a look at Open vSwitch, it looks interesting. I am a generalist, I need to know enough about a lot of things to get many different tasks done, but do not have the in depth knowledge required to "patch" anything.  If I manage to wrangle a working solution should I post it? Needless to say I would be supportive of said feature being implemented by those

Re: Controlling the name of the 'tap0' device, in a bridged networking setup
Thanks !! This clarifies completely what is happening. I'll look into running virsh as root/attaching to qemu:///system. Or, perhaps I can 'statically' create tun devices, to which the domains attach when started (although I have no idea weather this is possible).

Virtual Bridge "Network" for Sandbox
Hi all, I couldn't find any documentation on this, hopefully someone can point me in the right direction. I recently set up a sand-boxed environment for our developers. There are domain controller(s), workstations and servers in there.  The whole thing is running on a single host using a "Virtual Network" defined in virt-manager on that host. Now I find I want to add more

Re: F20 Virt-Manager with MacVTap not working
The guest was setup through virt-manager. The machine is not configured much after a F20 install (I believe I didn't change any network things) Here is the network part: <interface type='direct'> <mac address='52:54:00:fe:b0:66'/> <source dev='em1' mode='bridge'/> <target dev='macvtap0'/> <model

macvtap direct and ip spoofing
Hi there. I have configured kvm domain (rhel6.4) with ethernet bridged over macvtap, and found no filtration applied except mac. 'virsh' just silently ignoring attributes 'filterref' and 'ip address' in different formats. No error on validate stage. Config examples: ... <interface type='direct'> <mac address='52:54:00:31:ae:1a'/>

Re: Could you please help with questions about the net failover feature
Hi Laine, For the feature testing before, I only test the linux bridge setting as in 2), it works. Now I tried 1), to use macvtap bridge mode connected to the PF, it can not work as the hostdev interface can not get dhcp ip address on the guest. Check on host, the /var/log/messages and dmesg both says: "Jul 6 04:54:45 dell-per730-xx kernel: ixgbe 0000:82:00.1 enp130s0f1: 1 Spoofed packets

F20 Virt-Manager with MacVTap not working
Hello, I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT. When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the

Re: How libvirt interacts with dhcpd?
Thanks for the reply Laine. My problem is that dnsmasq is masking dhcpd, xCAT uses dhcpd for PXE stuff. If dnsmasq answer DHCP requests the PXE boot won' t work. I want to see the logs for ensuring the dnsmasq is not masking dhcpd. Regards, 2018-06-18 11:39 GMT-03:00 Laine Stump <laine@redhat.com>: > On 06/18/2018 09:16 AM, Daniel. wrote: >> Cool, thanks!!
