I have the following interfaces loc eth0 net0 eth1 net1 eth2 (net0 and net1 are the two ISP networks) policy loc net0 ACCEPT loc net1 ACCEPT net0 all DROP info proxyarp 209.189.103.204 eth0 eth1 no no params Pellucidar=192.168.124.232 rules DNAT net0 loc:$Pellucidar tcp 22,80,1950,50005 - 209.189.103.204 ACCEPT all all icmp

Greetings all, I have a host machine that runs a router within a vm. I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm. I've created a dummy interface with these commands: $ ip link add ens99-dummy type dummy $ ip link set ens99-dummy address 52:54:00:1f:d0:ff this resulted with this output: $ ifconfig ens99-dummy

Hi, CONFIGURATION: the important part of my setup looks like that (smb.conf): [global] interfaces = net1 net2 net3 net4 net0 ; this is a router which acts as cross-subnet domain master + wins ; server local master = yes preferred master = yes domain master = yes wins support = yes dns proxy = no os level = 99 net1 - net4 are Win95, WinNT, Linux net0 are two samba-1.9.18p1 fileservers

Hi, We've run into a problem with libvirt 1.1.2 and are looking for some comments on whether this is a bug or design intent. We're trying to use migrateToURI() but we're using a few things (numatune, vcpu mask, etc.) that may need adjustment during the migration. We found that migrateToURI2() mostly works if we use XML created by copying the domain XML from the running instance

I have a setup with two Internet providers. One circuit (net0 == eth1) is used primarily for employees and tunnels to other sites. The other (net1 == eth2) is for the production machines that customers access. Everythung works in teh sense that packets get to where they are sent (mostly) but I recently I had a sniffer on the system and noticed a problem I cannot solve. traffic coming in

Reports posted look good for me. Config should provide the best available performance for cloud VM (L2) on Compute Node. 1. Please, remind me what goes wrong from your standpoint ? 2. Which CPU is installed on Compute Node && how much RAM ? Actually , my concern is :- Number_of_ Cloud_VMs versus Number_CPU_Cores ( not threads) Please, check `top` report in

Hi, I'm investigating a performance issue on a virtualized windows server host that is run on a ubuntu machine via libvirt/qemu. While the host can easily read/write on the raid drive with 100Mmb/s as observable with dd, the virtualized windows server running on that host is barely able to read/write with at most 8Mb/s and averages around 1.4Mb/s. This has grown to the extent that the

Is there any way to get virsh / libvirt to create a domain such that I can later connect to it via QMP (without hacking the code)? The command line that libvirt creates for my current setup looks like this: /usr/local/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name winxpsp2 -uuid ab244939-c804-1aff-68b6-9324f174c3c8 -nodefconfig -nodefaults

Hello, In my C++ code, I generate my own domain XML file and I use virDomainCreateXML or virDomainDefineXML to launch my qemu VM. However, when I get to check which commands are sent to the qemu commandline, I find that libvirt has added so many extra parameters to the ones I have already set. How can I prevent libvirt from adding any extra parameters to the ones I originally defined in the

I would attempt to decrease number of VCPUS allocated to cloud VMs. Say try 4 => 2 . My guess there is not enough VCPUs to run OS itself. I also guess CPU model << Haswell. Please , confirm ( or not) if possible. Since Haswell was launched via my experience Intel Xeons based on this kernel (or latter kernels ) behaves much better then SandyBridge or IvyBridge based.

I am considering replacing my old checkpoint and watchguard firewalls witha single Linux box using iptables and shorewall. I have two ISP''s (with separate routing tables), two DMZ''s, at least one VPN to a remote office, and a local trusted network. The configuration will look like: +----------------+ | | net0 ----------+ eth1

I have a router with 3 network interfaces like in the following ASCII diagram below. All interfaces are 100mbit. There is tcp traffic being sent from net1 to net3 and from net2 to net3 and the tcp connections consume as much bandwidth as possible. There is a pfifo queue on the egress interface eth0 of the core router with a limit of 10 packets. net1 --> (eth1) router (eth0) -> net3

Hi guys, when I detach an interface from vm during boot (vm boot not finished), it always fail. I'm not sure if there is an existing bug. I have confirmed with someone that for disk, there is similar behavior, if this is also acceptable? # virsh destroy rhel7.2; virsh start rhel7.2 ;sleep 2; virsh detach-interface rhel7.2 network 52:54:00:98:c4:a0; sleep 2; virsh dumpxml rhel7.2 |grep

Hi, I have XEN 3.3 on Centos 5.4, my network interface have link 1 Gbps I want improve speed of network interface on virtual machine, from 100Mbps to 1Gpbs. Somebody have link that show do this ?

Hi all, I try to understand why the network bandwidth limits are not applied to my ubuntu 16.04.2 VM (qemu-kvm driver) and I would need some insights. I create my VM network with virsh and when I issue a dumpxml on my network, I can see that bandwidth limits are set: virsh # net-dumpxml nat_limit <network> <name>nat_limit</name>
