[libvirt-users] info about "migration check"
by Paolo Smiraglia
Hi guys! I'm Paolo, and I'm working on my graduation thesis.
One of my thesis' subject is to define a migration check which will be
used to perform "secure migration" using IMA measurement.
Someone can suggest me a documentation (code examples, technical
paper, etc) about migration cheks?
Now I'm analyzing libvirt source code to uderstand migration-cheks
mechanism, but the analysis has a ways to go......
Thanks!

[libvirt-users] No qemu-dm process for running domain
by Zhang Qian
Hi,
My C application is using libvirt to operate domains, but I found when I
started a domain with my application, there was no qemu-dm for this running
VM, and I can not access this domain with the graphic console provided by
virt-manager. But if I started the same domain with virsh which linked with
the libvirt shipped in OS, everything was OK, there will be a qemu-dm
process for the running domain, and the graphic console provided by
virt-manager worked well.
The libvirt used by my application is libvirt-0.6.4, I just downloaded
libvirt-0.6.4.tar.gz from
http://libvirt.org/sources/old/libvirt-0.6.4.tar.gz, and I built it by
running "./configure --prefix=/usr && make". Here are the details of my
machine:
# cat /etc/redhat-release
Scientific Linux SL release 5.4 (Boron)
# uname -an
Linux ib06b07 2.6.18-164.11.1.el5xen #1 SMP Wed Jan 20 08:53:10 EST 2010
i686 i686 i386 GNU/Linux
Was there anything wrong when I built libvirt-0.6.4? Should I enable some
compilation options for launching qemu-dm process for running domains?
Any suggestions will be really appreciated, thanks in advance!

Qian

[libvirt-users] ESX access using libvirt
by Jonathan Kelley
Hello,
I am trying to access an ESXi host using libvirt but it seems that it
requires netcat to be running on the ESX server.
My ESX 4 does not have this installed and I am wondering if this is
required or is there some other way to get this working?
Thanks,
Jon

[libvirt-users] Libvirt Auth
by Marco Mornati
Hello guys,
I've created a plugin for Hudson (CI) to manage virtmachines using
libvirt java (start vm for a build and stop just after).
I've just a problem in authentication, in fact I cannot send uname and
password using code, libvirt ask me for the credentials on CLI.
someone could explain me How I can use authentican or where I can find
an usage guide or example?
Thanks a lot
Bye

[libvirt-users] Libvirt and openvz?
by Thomas Graves
I just recently started using openvz and I'm trying to use libvirt/virsh
with it.
I followed the directions on page: http://libvirt.org/drvopenvz.html
But I get an error trying to run define with the example config file:
virsh define virt.conf
error: Failed to define domain from virt.conf
error: unknown OS type exe
I'm using libvirt 0.7.2.
Does anyone have more example configuration files or other setup
instructions?
Does Libvirt allow you to specify other resource limits and controls that
openvz has - like vzctl set --devnodes device:rw or vzctl set kmemsize?
Thanks,
Tom

[libvirt-users] location of network xml files
by carlos campderrós
Hello,
On Ubuntu 9.04 (libvirt 0.6.1-0ubuntu5.1) I have 2 different network files:
root@sauron:~# ls -l `locate default.xml`
lrwxrwxrwx 1 root root 14 2010-02-13 12:34
/etc/libvirt/qemu/networks/autostart/default.xml -> ../default.xml
-rw-r--r-- 1 root root 373 2010-03-01 00:02
/etc/libvirt/qemu/networks/default.xml
-rw------- 1 root root 319 2010-03-01 00:04
/var/lib/libvirt/network/default.xml
Modifications I do on the /etc file are ignored (I'd like to modify the dhcp
range and set fixed ips to VM mac addresses). I don't understand why this
file is there, as it seems ignored by everything, and why the autostart
symlink points to it instead of the /var/lib/libvirt one.
Is it reasonable to symlink (or hardlink if possible) one file to the other?
Or to remove the /etc file and point the autostart to the /var file? Also,
does the autostart do something? because it's pointing to the ignored file.
thanks,
carlos.
