Thank you, that's it! virsh vol-list storage VM1   /dev/storage/VM1.img VM2   /dev/storage/VM2.img VM3   /dev/storage/VM3.img [dead] VM4   /dev/storage/VM4.img [dead] A last stupid question (I don't want to make a big mistake ...): Is virsh vol-delete VM3 virsh vol-delete VM4 the right command to get rid of the offending ones?

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:

Hi there, I have a question regarding the shares option of the cputune section. I want to illustrate my question with the following example. Let's assume I have two virtual machines like the following on four dedicated core with two threads each: VM1: <cputune> <shares>512</shares> <vcpupin vcpu="0" cpuset="0"/> <vcpupin

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 *

HI I have 15 vm (libvirt + kvm) with a network brigde and ip address like 192.168.0.1 VM1 192.168.0.2 VM2 192.168.0.3 VM3 ..... The vm are use by other people and I want to be sure that if someone change the ip of VM3 to 192.168.0.1 it will filter it network traffic for him and can't flood the VM1 What the best way to achieve this Hope I m clear enough

Libvirt doesn't care about security during hot add disk images. It even accepts addition of disk images of other guest running on the host. Steps followed to create this scenario : Started two VMs with following security configurations: vm1: <seclabel type='dynamic' model='selinux' relabel='yes'>

Hi, I have 3 xen box with 2-3 VM on each. Each server has 2 nic (1 for external and 1 for internal network). All VMs are webserver and they mount a nfs filesystem. I''ve noticed that on each dom0 there are many dropped packets. Server config is: 1- DELL (2xQuad Xeon E5320 @1.86Ghz - 8Gb Ram - Perc5 - Kernel 2.6.18-6 (debian etch)) 2- DELL (2xDual Xeon 5110 @1.60Ghz - 4Gb Ram - Perc5 -

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.

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

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

I am using a VM with CentOS 5.8 x86_64 under KVM. I only have console access to the VM through a virtual console (web based). Tonight, after a routine "yum update", I did a "shutdown -r now" due to kernel update and the VM won't start. See console screenshot vm1.png: https://vmail.noa.gr/files/vm1.png There is an error (which I haven't seen before): type=1404

Hi. I am a student at University of Zurich and I''m doing a homework about Cloud Computing regarding accounting and billing. Because the "big" players use Xen Hypervisor I installed a Xen (3.3.0) on an Ubuntu 8.04 to test some things and get more familiar with Xen regarding accounting. I have two questions: 1. CPU monitoring +++++++++++++++++ I have discovered something

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

This problem appears to be related to the sqlite3 DB files that are used for the tiering file access counters, stored on each hot and cold tier brick in .glusterfs/<volname>.db. When the tier is first created, these DB files do not exist, they are created, and everything works fine. On a stop/start or service restart, the .db files are already present, albeit empty since I don't have
