[libvirt-users] bridge and route without IP
by Robert Šmol
Hi,
I want to forward all traffic received on eth1 into virtual domain
'firewall' (where I want to configure public IP+shorewall)
I've created following network:
node002 qemu # cat networks/int-001.xml
<network>
<name>int-001</name>
<bridge name="intbr0" />
<forward mode="route" device="eth1"/>
</network>
virsh # net-create networks/int-001.xml
error: Failed to create network from networks/int-001.xml
error: internal error Forwarding requested, but no IP address provided
But wan to set the public IP on the Firewall side. How do I do that?
Would the macvtap help me?
Regards,
Robert

[libvirt-users] ANNOUNCE: oz 0.3.0 release
by Chris Lalancette
All,
I'm pleased to announce release 0.3.0 of Oz. Oz is a program for doing
automated installation of guest operating systems with limited input from the
user.
Release 0.3.0 is mostly a bugfix release for Oz. However, there are also
a few minor features included as well. Some of the highlights between Oz 0.2.0
and 0.3.0 are:
- Add the ability to specify the output directory for screenshots (the default
is still CWD).
- Add the ability to specify the bridge to use for installs (the default is
still the first libvirt NAT bridge on the system).
- Nicer error messages from the command-line tools when debugging is off.
- Add the ability to install Debian 5 and 6.
- Detect servers that can't possibly work for installing RedHat/Fedora OSs,
and fail the install.
- Allow installs with spaces in the name.
- Add the ability to install OpenSUSE 11.4.
More documentation on Oz is available here: http://aeolusproject.org/oz.html
If you have any questions or comments about oz, please feel free to contact
aeolus-devel(a)fedorahosted.org or me (clalance(a)redhat.com) directly.
Thanks,

[libvirt-users] ESX networking functions
by James Barkley
Greeetings,
Using the latest git snapshot I noticed that none of the networking
functions are implemented in the ESX driver. No listing networks, no adding
networks, etc. This functionality seems to be fully implemented for most of
the other drivers and I don't see it on the "todo" wiki. Does anyone have an
idea if/when this might get implemented? Would others be interested if I
were to add it and submit it as a patch?

[libvirt-users] How to disconnect the ISO image using virsh
by Masanari Iida
Hello,
I can attach disc ISO image to cd-rom from virsh.
And I can replace the ISO image from disc1 to disc2 using the 2nd example.
(example)
attach-disk guest01 /root/disc1.iso hdc --driver file --type cdrom
--mode readonly
attach-disk guest01 /root/disc2.iso hdc --driver file --type cdrom
--mode readonly
My question is, how can I disconnect the image from the cdrom drive using virsh.
Because, if I try to detach-disk hdc, I got following errors.
virsh # detach-disk guest01 hdc
error: Failed to detach disk
error: this function is not supported by the connection driver:
This type of device cannot be hot unplugged
What I can do is possible from virt-manager's "Disconnect" button,
(next to source path: line) from Hardware's TAB, Disk hdc screen.
I want to do this from virsh.
OS: RHEL5.6
libvirt-0.8.2-15.el5_6.1 is used.
Regards,
Masanari Iida

[libvirt-users] block migration
by mkey
Hello,
I'm trying to use block migration with below procedure, but got some errors. I would highly appreciate if anyone give me a hand..
There are 2 hosts(hostA and hostB), both OS is Ubuntu 10.10(merverick). And a VM(named centos54-1mg) is running at hostA(centos54 64bit).
[package version]
+++-=====================-=====================-===================
ii kvm 1:84+dfsg-0ubuntu16+0 dummy transitional
ii libvirt-bin 0.8.8-1ubuntu3~ppamav the programs for
ii qemu-common 0.14.0~rc1+noroms-0ub qemu common
ii qemu-kvm 0.14.0~rc1+noroms-0ub Full virtualization
[proceduere]
root@hostA:~# /etc/init.d/apparmor teardown
root@hostA:~# stop libvirt-bin && start libvirt-bin
root@hostB:~# /etc/init.d/apparmor teardown
root@hostB:~# stop libvirt-bin && start libvirt-bin
root@hostB:~# touch /tmp/centos54-1mg.img
root@hostB:~# chown -R libvirt-qemu:kvm /tmp/centos54-1mg.img
root@hostA:~# virsh migrate --live --copy-storage-all --p2p --direct centos54-1mg qemu+tcp://hostB/system
[NOTE]
1. What I was being careful is permission. Therefore, apparmor is off, libvirt is running as root.
2. normal live migration is successfully finished. So, libvirtd can communicate between hostA and hostB.
3. Regarding to options "--live --copy-storage-all --p2p --direct", I think --copy-storage-all is minimum, so I was trying to change pairs of options, but no good result.
The error logs and configuration at hostB are attached.
Thanks in advance

[libvirt-users] Event Types Libvirt can handle
by kadir yüceer
Hello all,
I'm trying to observe access events of guest VMs. However, as far as I
understand event types in libvirt are really generic, like domain
defined/undefined, started/stopped, etc.
Isn't there any specific event types that libvirt can handle (like access to
a disk), or I'm missing them?
Thanks in advance
Kind regards

[libvirt-users] virsh sechedinfo with libvirt-0.8.8
by Zvi Dubitzky
I have fedora14 installed with standard libvirt-0.8.3. I can start VM
using .xml files and also run: virsh schedinfo. the cgroup CPU
controller is mounted and active . In fact I have the path to the Virtual
machine : /dev/cgroup/cpu/libvirt/qemu/<vm name >
Now I upgraded to libvirt-0.8.8 from a tar ball ( configure , make , make
install) . I rebooted , new libvirtd started . virsh is working ok
(I can create a vm) except for the commands : schedinfo and memtune that
say upon ' virsh schedinfo <vm name>'
Scheduler : Unknown
error: Requested operation is not valid: cgroup CPU controller is not
mounted
Indeed I have the path : /dev/cgroup/cpu/libvirt/qemu/ but now without
the <vm_name> group which is not generated despite
that the VM was generated ok by virsh and I can access it
Any idea what is missing or some config file needs a change ?
thanks
