[libvirt-users] error: authentication failed: Authorization requires authentication but no agent is available
by Yih Chuang
I ran into this error. Any way to fix it?
[vmcuser@rhel60h207kvm .ssh]$ virsh -c qemu+ssh://
vmcuser(a)9.10.110.241/system list --all
error: authentication failed: Authorization requires authentication but no
agent is available.
error: failed to connect to the hypervisor
Here is my settings different from default:
[root@rhel60e201c libvirt]# diff libvirtd.conf libvirtd.conf.old
81c81
< unix_sock_group = "vmcuser"
---
> #unix_sock_group = "libvirt"

---
> #unix_sock_rw_perms = "0770"
129c129
< auth_unix_ro = "none"
---
> #auth_unix_ro = "none"
[root@rhel60e201c libvirt]# diff qemu.conf qemu.conf.old

Thanks.

[libvirt-users] no callback on VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE in 0.10.2
by Ben Clay
I'm trying to track balloon growth after issuing a setmem command to a KVM
guest with libvirt 0.10.2 and qemu-kvm 0.12.1.2 on CentOS 6.3. libvirt
0.10.2 was built from tar today and appears to be working fine. The guest
is running CentOS 6.3 as well.
Using the provided test programs under examples/domain-events/ in C and
Python, I'm not seeing VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE ever tick,
although I do see other events like VIR_DOMAIN_EVENT_ID_LIFECYCLE,
VIR_DOMAIN_EVENT_ID_REBOOT, and VIR_DOMAIN_EVENT_ID_RTC_CHANGE. The balloon
is definitely changing, and is reflected by both virsh -c qemu:///system
dommemstat <dom> and free inside the guest. Here's the balloon in my config
for reference:
<memballoon model='virtio'>
<alias name='balloon0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05'
function='0x0'/>
</memballoon>
Is my understanding incorrect of what VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE is?
Is there something else this event is tracking, other than a virsh -c
qemu:///system setmem <dom> <mem in KB> command and/or subsequent balloon
movement inside the guest? Or, is my old version of qemu-kvm not passing
this event back to libvirt? The latter doesn't seem correct because I'm
getting seemingly-valid values from dommemstat - ie, if I setmem 200MB when
the guest OS and applications are consuming 300MB, it reports near 300MB
(and the guest no longer responds) instead of just parroting the 200MB value
I fed it.
Thanks!

[libvirt-users] Problems connecting with a remote VirtualBox server
by john Sanabria
Hi,
I want to connect to my VirtualBox hypervisor using a string connection
similar to this virsh -c vbox+ssh://localhost/session but it does not work
however I can run virsh -c vbox:///session successfully.
josanabr@leader:~$ virsh -c vbox+ssh://localhost/session
error: End of file while reading data: : Input/output error
error: failed to connect to the hypervisor
josanabr@leader:~$ virsh -c vbox:///session
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands

I have not modified any libvirt configuration file. I appreciate your
feedback.

[libvirt-users] IPv4 routed virtual networks
by Gene Czarcinski
OK, either I have taken a stupid pill and am missing something basic or
routed network do not work.
I assume that, if they did work, it would be in more or less that same
manner as a nat network as far as ping'ing, ssh'ing, etc. to another
real host on the same real LAN as the virtualization host. At least that
is what I believe I should expect.
I have googled for info and everything says that it should work. On of
the referenced documents was this:
http://berrange.com/posts/2009/12/13/routed-subnets-without-nat-for-libvi...
I checked through everything and it all matches what is in the
document. I can go from the guest to the host (ping, ssh, etc) but not
from that guest to another real host on the same real LAN.
I am patching the relevant info below:
----------------------------------
net.ipv4.conf.all.forwarding = 1
net.ipv4.conf.p32p1.forwarding = 1
net.ipv4.conf.virbr8.forwarding = 1

------------------------------
This is Fedora 17 with an updated libvirt 0.10.1-4.fc17 [another system
with the same "problem" is running libvirt 0.10.2-1.fc17].
Anyone know what is going on?
BTW, I searched bugzilla for the comment containing the string routed
filed against packages libvirt, qemu, qemu-kvm, or kvm ...Result .. no hits!
If this is really a bug rather than something I did or did not do, then
nobody is using routed virtual networks.
BTW, I have a real F17 systems sitting between to networks on two
different NICs and it routes things nicely, thank you very much. It
does work but not for the virtual networks.
I would really like it to be something I am missing.

[libvirt-users] libvirt Java to connect at the XEN
by Felipe Oliveira Gutierrez
Hi people, I am new using libvirt for Java
I created a class to test my conecction with XEN, but it is throwing a
exception that I can't figure out how I solve this.
Does anyone knoe how to configure it correctly?
I cat use this class from the command line:
$ javac -classpath /usr/java/jdk1.6.0_34/bin/libvirt-0.4.9.jar test.java
$ java -classpath
.:/usr/java/jdk1.6.0_34/bin/jna.jar:/usr/java/jdk1.6.0_34/bin/libvirt-0.4.9.jar
test
and it connect to the XEN.
But when I put the code on my eclipse it doesn't work any more.
...
conn = new Connect("xen:///", true);
....
