I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:

Is it possible to use this exploit against a kvm guest to read memory used by the host? In other words: if an exploitable service, say httpd with mod_ssl, is running in guest system 'vm1' hosted on system 'virthost' then what implications does that have with respect to guests vm2 and vm3 and to virthost itself? -- *** E-Mail is NOT a SECURE channel *** James

libvirt-users@redhat.com TCP Tunnel Info I've been looking at the TCP Tunnel network feature as a potential replacement for the extra private internal networking configuration file. Usecase: This network is supposed to go from VM1 to VM2 without DHCP, DNS or any incoming/outgoing connections to the host or outside world possible. https://libvirt.org/formatdomain.html#elementsNICSTCP *

Hello, My testing machine has 2 quad-core CPU (It supports hyperthreading, but i disable it in BIOS). I uses Xen 4.0.1 as the hypervisor. When I use 8 VMs to conduct a test, CPU affinity of the VMs is very strange. Like this: vm_name vcpu_num cpu_affinity Domain-0 8 any VM1 4 1,3,5,7 VM2 4 1,3,5,7 VM3 4 1,3,5,7 VM4 4

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was

To take advantage of the filters, is it as simple as adding these couple of lines in a guest's xml file like the example from https://libvirt.org/formatnwfilter.html#nwfconcepts ? <devices> <interface type='bridge'> <mac address='00:16:3e:5d:c7:9e'/> <filterref filter='clean-traffic'> <parameter name='IP'

Hi Michael, Looks like the discussions tapered off, but do you have a plan to implement this if people are eventually fine with it? We want to extend this to support multiple VMs. On Mon, Aug 31, 2015 at 11:35 AM, Nakajima, Jun <jun.nakajima at intel.com> wrote: > On Mon, Aug 31, 2015 at 7:11 AM, Michael S.

Hi Michael, When you talk about VFIO in guest, is it with a purely emulated IOMMU in Qemu? Also, I am not clear on the following points: 1. How transient memory would be mapped using BAR in the backend VM 2. How would the backend VM update the dirty page bitmap for the frontend VM Regards Varun > -----Original Message----- > From: qemu-devel-bounces+varun.sethi=freescale.com at nongnu.org
