libvirt version: 3.4.0 architecture: x86_64 ubuntu16.04-server hypervisor: kvm,qemu I call virDomainCreate create a transient vm, After a period of time ,I call virDomainDestroy, the vm configure is stil exist， the vm turn to persistent, I don't known the reason. Thanks

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

Hi, If I have these fragments in a domain definition, the guest will start with "eth0" assigned by dhcp to an address on my lan. Things seem to work according to the documentation I can find. <network> <name>direct-macvtap</name> <forward mode='bridge'> <interface dev='eth0' /> </forward> </network>

I am building a custom Linux image which includes KVM and will be installed on multiple machines. By default when installing libvirt you get a 'default network' which adds a 'vrbr0'. I found several tutorials online about removing this 'virbr0' but I would like to not have it in the first place. I am compiling libvirt from source so I would think there is some compile time

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

Hi, I just tested in the lab the new CentOS 5.1 Xen and find out it breaks network connectivity, at least in my setup. It seems it is somehow making use of the 3.1 Xen version (altought I am not sure about that) but whatever changes it introduce is not documented at the location one would expect, the obvious new thing (at least for me) is this thing I will call out of guessing a virtual

Hi , I have two virtual machines VM1 and VM2. Then I have added eth0 of my VM to 'default' network. Use case :- I want to monitor all traffic on virbr0('default' network). Steps followed :- 1. Add VM1 eth0 to virbr0 2. Add VM2 eth1 to virbr0 3. brctl setageing ovsbr0 0 ..(To put bridge in promiscuous) Now I am running tcpdump on eth1 of VM2 and trying to ping

Interested in bonding my 2 on board nics along with my add on card NIC for a total of 3. How would this work with the virtual machines? My eths/IPs ---> bond0, bond0:1, etc ---> ? ----> virbr0,virbr0:1 (each machine to have own IP address, one machine may have some virtual sites needing more than one ip, so multiple ips added to mix..) add something to the bond0 file, or just leave

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

Hello, I came across an interesting problem in my home lab a few weeks ago as I'm prepping for my RHCE exam using Michael Jang study guide. I've been at this for days now, and I still can't wrap my head around how two or more virtual networks in default NAT configuration are even allowed to communicate with each other despite what the libvirt documentation said. Here's the

Dear LLVM developers, Hello, I'm trying to find a way of cross-compiling my c code against Baremetal Cortex-M device (so target triple will be arm-none-eabi) only using LLVM/Clang, and not using anything from GNU (ld or libc). I'm doing this to know which one of LLVM/clang and GCC produces smaller flash image size because saving flash is a big deal in our projects. 1) When I just follow

Hi, I got this NOTE on most of the link. But I am not getting reason for this. Why someone should not add physical NIC to virbr0. I tried to add my eth1 to virbr0 and it get added. So whether it affects to some functionality of NAT network? -- Sagar Dilip Shedge, Pune. With Regards.

Just want to report an error in samba configuration / setup. I installed Samba 4 GA on a fresh installation of Ubuntu 12.04. The server is a testbed and has the virtualization package installed also. I have two network interfaces exept lo: eth0 and virbr0. In the provisioning step samba correctly finds my eth0 network interface: Looking up IPv4 addresses More than one IPv4 address found.

Hey, I am getting this error after using virt-v2v-copy-to-local and trying to run: $ virt-v2v -i libvirtxml rhel7.xml -o local -os /var/tmp -of raw I try to set: export LIBGUESTFS_BACKEND_SETTINGS=virbr0=ovirtmgmt with no success and the file /etc/qemu/bridge.conf contains: allow virbr0 it only worked after creating the bridge, is there other way to import without creating the bridge?
