Port forwarding for KVM
...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...

Actually, we do not use any special feature from QEMU. Just basic
things. 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

Thanks! I will take a look on this.

qemu-system-x86_64 does not support fw_cfg option
...the qemu documentation, see
here
<https://qemu.weilnetz.de/doc/qemu-doc.html#Debug_002fExpert-options>,
they support this option.
The command used to run the vm is:
/usr/bin/qemu-system-x86_64 -name CL-IGN-1 -m 1024 \

-net user,vlan=0,hostfwd=tcp::2222-:22,hostname=CL-IGN-1 \

virt-builder and Ubuntu 16.04 Xenial no access issue
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

Questions regarding migration from QEMU to libvirt
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

ERROR: Domain not found: no domain with matching name 'ubuntu'
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

find domain.
I seek your kind help on below error:
