...virtual machine, then get that QEMU's vnc output. I am using libvirt 0.9.13 (`libvirtd --version`), and attach is my vm's original config xml. Is there a simple way to achieve my goal? I was told that iptable solution I found on the web is for "tap" interface, and I can use "hostfwd" QEMU option if I use "user" interface. For the latter approach, I basically follow this one [1] with the QEMU cmdline option below: <qemu:commandline> <qemu:arg value='-net user,hostfwd=::5902-:5901'/> </qemu:commandline> But virsh always keep say...

Just for illustrate, follows the command that we use for start a VM: qemu-system-x86_64 -enable-kvm -daemonize -m 3G -smp cores=4,cpus=4 -net nic \ -net user,hostfwd=tcp::2222-:22,smb=/home/USER /home/USER/p/DISK.qcow2 > If you only need the disk to stay the same and you want to easily migrate > existing machines, then virt-v2v might be good to try.

...the qemu documentation, see here <https://qemu.weilnetz.de/doc/qemu-doc.html#Debug_002fExpert-options>, they support this option.

Hello, I created an Ubuntu 16.04 Xenial guest using virt-builder(1) with # virt-builder ubuntu-16.04 -o /var/lib/libvirt/images/ubuntu-16.04.qcow2 --size 10G --format qcow2 --firstboot-command 'dpkg-reconfigure openssh-server' --arch x86_64 And imported it to libvirt with # virt-install --import --name ubuntu-xenial --ram 2048 --disk

Hi, My colleagues and I have a set of scripts that we use to automate our daily tasks related to the Linux Kernel. As a result, most of our code relies on the QEMU features; and recently we decided use libvirt instead of QEMU. However, we have some questions, and I would like to know if someone could help us. Follows: 1) Import our QEMU images with virsh Currently, we import the QEMU VMs with

Hi guys, I am new to QEMU-KVM, libvmi and libvirt stuff. Libvmi uses libvirt. I am trying to to run process-list example of libvmi and getting error as below. It seems that this error may be due to libvirt as it is not able to find domain. I seek your kind help on below error: spanhal1@seclab2:~/KVMModule/libvmi-0.10.1$ sudo ./examples/process-list ubuntu libvir: QEMU error : Domain not found:
