[libvirt] networking static ip address
by Francisco José Martín
Hi, we are using the 0.6.0 version and an Ubuntu guest os under KVM
virtualization.
We have tried several ways to assign a static ip address to the guest os
eth0 device on boot, but we didn't success. Is there any easy way to do it?
We are trying to have a guest with the ip 192.168.0.1 in the eth0 device,
enslaved to the br0 bridge on the host machine, which seems to be a pretty
easy setup to test.
When the guest OS is booted, the eth0 device exists, but is not up, and
doesn't have the IP.
Regards,
Francisco.

[libvirt] networking with VMs on two nodes
by Andreas Rittershofer
I have two nodes and on each several virtual machines running under
KVM/qemu. I've set up the default-network on each node and so I can:
1.) ping from host do guest
2.) ping from guest to host
3.) ping from guest tu guest
But all this is only possibe on each node by itself.
What I need now is network connection between a VM on node 1 to
another VM on node 2. How to setup this?
When both nodes are fine every node runs a few guests. But when one
node goes down, all guests have to be run on the remaining node.

[libvirt] Re: [et-mgmt-tools] attach hot usb device

cc-ing libvir-list (future libvirt questions should be directed there)

Sure:
- Use 'lsusb' to determine the bus and device. Example listing looks like:
Bus 001 Device 006: ID 0781:5151 SanDisk Corp. Cruzer Micro 256/512MB
Flash Drive
- Put hostdev xml in a file:
cat << __EOF__ > usb.xml
<hostdev mode='subsystem' type='usb'>
<source>
<address bus='1' device='6'/>
</source>
</hostdev>
__EOF__
- Run 'virsh attach-device {VMNAME} usb.xml' on a running VM.
Hope that helps,
Cole

[libvirt] Networking with libvirt
by Andreas Rittershofer
I want to setup networking under KVM and with libvirt. I read a lot
the last two days, but it is not working as desired. I don't want
bridging, I want it with a tap-device created via vde_switch. I cannot
figure out what to put in /etc/libvirt/qemu/machine.xml and /etc/
libvirt/qemu/networks/network.xml - there is no really good
documentation. /var/log/libvirt/qemu/maschine.log shows a lot of
parameters when I start the VM with virsh start machine, but I cannot
figure out where to set these values or where to set the defaults.

I hit a small snag when following the documentation, specifically
the doc says to use <clock sync='localtime'/> when it should say
<clock offset='localtime'/>.

[libvirt] restore as init script
by Matthias Pfafferodt
Hello,
first i'm using kvm-84 and libvirt 0.6.0 on opensuse 11.1.
I try to use the attached script to save some domains on shutdown and restore
them on host boot. The script also tries to cleanly shutdown all other
domains. The save and shutdown part is working as expected but on system boot
the restore of the saved domains fails. If I manually run 'rclibvirtdomains
start' after a boot it needs 1 to 3 tries to restore the domain. After that I
can run a stop/start cycle of libvirtdomains without problems.
How can I debug this problem? After the system boot libvirt seems to have
problems to connect to qemu/kvm. The log messages are for a failed start:
--- start log ---
LC_ALL=C PATH=/bin:/sbin:/usr/bin:/usr/sbin HOME=/ /usr/bin/qemu-kvm -S -M

[libvirt] bridge-to-lan interfaces with network type
by Zhengang Li
Hi All,
The documentation on the libvirt website explains the way to define a
bridge to LAN network interfaces with a 'bridge' type. E.g.:
<interface type='bridge'>
<source bridge='br0'/>
<mac address='52:54:00:00:00:11'/>
</interface>
I'm working in a limited environment. Only 'network' type interfaces can
be defined for a guest. Is it possible to define a bridge-to-lan
interfaces with a 'network' type? The question actually goes to: How to
write a network definition xml for libvirt to use as bridge to LAN type
NIC in guest?
I tried with 'nat' and 'route' forward in network xml, neither works for me.
Regards,
Zhengang
