[libvirt-users] libvirt, OSX and VirtualBox - how?
by Brian Candler
I have a new OSX Lion Macbook and would like to control VirtualBox using
"virsh" (as I do with KVM under Ubuntu).
I've got this far:
* Installed VirtualBox
* Installed libvirt (brew install libvirt)
But now I'm a bit stuck :-)
I ran VirtualBox itself, and created a test VM successfully.
If I try to use virsh, this is what I get:
Brians-MacBook-Air:~ $ virsh -c vbox:///session
error: internal error unable to initialize VirtualBox driver API
error: failed to connect to the hypervisor
Brians-MacBook-Air:~ $ virsh -c vbox+unix:///session
error: Failed to connect socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory
error: failed to connect to the hypervisor
If I try to start libvirtd, this is what I get:
Brians-MacBook-Air:~ $ /usr/local/sbin/libvirtd
00:00:18.970: -1: info : libvirt version: 0.9.6
00:00:18.970: -1: error : virNetSocketNewListenUNIX:340 : Failed to bind socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory
[but directory /Users/brian/.libvirt was created]
However, VirtualBox itself is running OK:
Brians-MacBook-Air:~ $ VBoxManage list vms
"test" {d0d74c25-1dfc-44a4-8a2b-1d25b7972e7c}
Furthermore, dtruss suggests that virsh is finding the installed VirtualBox:
Brians-MacBook-Air:~ $ sudo dtruss -f virsh -c vbox:///session 2>&1 | grep -i virtualbox
error: internal error unable to initialize VirtualBox driver API

But looking at the dtruss output shortly before it prints the error message
doesn't give me any clues as to what's going wrong.

Has anybody got libvirt + OSX Lion + VirtualBox working, and if so, how did
you do it?
I see the same question asked here:
http://stackoverflow.com/questions/7946994/libvirt-and-virtualbox-on-osx
but unfortunately no response as yet.
Thanks in advance,

In the future it is usually best to keep one of the lists on an email; that
way, if I'm away or not responding, someone else can help you. I've added
libvirt-users to this response.
In any case, you have the right idea. Libvirt is a control plane for various
different virtualization solutions. Arguably the most popular virtualization
solution that libvirt can control is KVM, but it can also manage Xen, VMware
ESX, LXC (linux containers), UML, etc.
Libvirt provides both tools (like virsh and libvirtd) and APIs for interacting
with virtual machines. The APIs are things like virDomainShutdown(),
virDomainReboot(), etc. The ruby-libvirt package is a thin wrapper around
these APIs, so that you can use this functionality from ruby programs. That
is, you would be able to do something like:
dom.reboot
dom.shutdown
from your ruby programs. There are also bindings for other languages such
as python, php, and perl.
There is a lot more information at http://libvirt.org, and there is more
information specifically about the ruby bindings at http://libvirt.org/ruby

[libvirt-users] libvirtError: internal error cannot find PCI address for balloon virtio
by Wouter
Hi guys,
I have a little problem here. When I want to install a virtual machine I get
this error:
libvirtError: internal error cannot find PCI address for balloon virtio
Libvirt is running on a debian 5 system with kvm and of course libvirt. How
can I solve this problem, I searched on the Internet but there aren't posts
about this problem yet. So I don't have an idea where to look for.
I hope you guys can help me.
With kind regards,
Wouter.

[libvirt-users] virt-manager: create lxc app container hangs
by sean darcy
libvirt-0.9.6-2.fc15.x86_64
virt-manager-0.9.0-7.fc15.noarch
I'm trying to use virt-manager create a simple lxc app container just to
see how it works. App is /bin/sh, 128 megs, 1 cpu.
All seems to go well, but when I click "Finish" and the "Creating
Virtual Machine" box comes up, "Creating Domain..." stays at 0B though
the slider keeps going back and forth.
Nothing in /var/log/libvirt/libvirtd.log
No relevant log in /var/log/libvirt/qemu/
Any help appreciated.

[libvirt-users] Finding out if Xen or KVM is used
by PREETHI RAMESH
I've got 2 doubts:
1.I've been trying to write an application using Libvirt's Java API which
should run on both Xen and KVM running machines and execute the Xen or KVM
code based on the hypervisor used. I want the physical machine to know if
it's running Xen or KVM and execute only that code.
While using getURI(), I need to use it as
conn.getURI()
but then I can't use conn without declaring it previously as Connect
conn=new Connect("URI");
Is there any way to get the URI used and hence the hypervisor used?
2. This question concerns the usage of the listDomains(). When I run this
piece of code in KVM, it works perfectly fine but throws an array out of
bounds exception in Xen.
Connect conn=null;
conn = new Connect("xen:///", true);
int[] id = conn.listDomains();
System.out.println("lD of VM " +id[0]);
Thanks for your time.

[libvirt-users] Libvirt exiting and respawning
by Stephen Eilert
Hi,
I'm trying to use Libvirt with LXC, under Ubuntu 11.04, but I can't get it
to work. It keeps exiting and being restarted by upstart. Log file follows.
It appears that it is complaining, among other things, of QEMU. I am not
running QEMU and would like to disable everything except for LXC, but I am
not sure it would fix my issue. I've set the log level to debug, even, but
didn't see anything out of ordinary. Even resorted to strace, but I don't
know enough about libvirtd to try and understand its behavior.
Anyone got any clue about what's causing it to decide to exit?

[libvirt-users] Event&Callback in QEMU
by huachao yao
Hi buddy,
I wanna to monitor a domain's life cycle event, so i register a event an a
virConnectDomainEventCallback, the code segment is as below:
------------------------
int DomainEventCallback(virConnectPtr conn,
virDomainPtr dom,
int event,
int detail,
void * opaque){
/*My code */
.......
}
int main(){
/* .....*/
virDomainPtr dom = domain.getDomains("xp");
virFreeCallback freecb = NULL;
void *opaque =NULL;
virConnectDomainEventCallback cb =DomainEventCallback;
virConnectDomainEventRegisterAny(conn, dom,
VIR_DOMAIN_EVENT_ID_LIFECYCLE,
VIR_DOMAIN_EVENT_CALLBACK(cb),opaque,freecb);
/* .....*/
}
but such a error happened:
libvir: Remote error : this function is not supported by the
connection driver: no event support
and the libvirt version is 0.9; the driver is QEMU-KVM ,version is 0.14.0.
I want to know why this Error will happen? Is the QEMU not support the
LIFECYCLE Event ? If it is , how can i monitor the domain's life cycle
event( such as started,defined and stopped..)
Pls help~~

[libvirt-users] Cannot start VM after restart libvirt daemon
by Jean-Luc Derrien
Hello all,
I'm using libvirt 0.8.3 on Debian Lenny (package provided in
lenny-backports).
After restarting libvirtd, I cannot start VM anymore.
The daemon is restarted, but each time I try to start a domain, I get this
message :
virsh # start vm2
error: Failed to start domain vm2
error: internal error Process exited while reading console log output:
When daemon is started with -v argument :
18:20:26.142: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit

When I reboot the server it works.
Help welcome. Thanks in advance.

[libvirt-users] general protection errors
by Alex
Hi,
Some time ago I sent a message about some general protection errors,
and didn't receive a response. I hoped I could post again and that
someone might have some ideas. I really don't think it is a hardware
problem producing these errors, but am otherwise out of ideas.
I'm having a problem with a fedora15 x86_64 host with a fedora15
x86_64 guest on a Xeon E3-1240 with 8GB RAM on the guest. This is the
only guest. The server is configured as a mail server, using
spamassassin, postfix, amavisd, and clamav.
Have there been significant changes in the current version from 0.8.8
that is shipped with fedora15?
It was previously running without error on different hardware. I
migrated the disks to a more powerful server due to load. It's a new
server, and has been stress tested with memtest86, mprime, and
passmark's Linux test for more than 24 hours without producing a
problem.
However, when I run the kvm vm, I receive a bunch of errors similar to
these on the guest:
[169245.360511] clamscan[27448] general protection ip:7f125f2e6ffb
sp:7fff117566f0 error:0 in libclamav.so.6.1.11[7f125f229000+9ce000]
[29016.445470] clamd[1110] general protection ip:30df2c3981
sp:7fffa08f4fe0 error:0 in libclamav.so.6.1
.11[30df200000+9ce000]
There are other applications, such as pyzor, that produce similar errors.
Is this something that could be a result of some software
configuration error I've made? Is there something I can do to debug
this further? There also aren't any errors on the host indicating a
kernel problem or hardware issue.
Is it possible this is a known error?
I was previously trying to improve IO performance by using 'block'
instead of 'file' for the device, but had to abandon that idea because
it didn't work and I had to concentrate on this problem.
Could disabling the cache (cache=none) cause this?
I've included some info below, in hopes someone could guide me towards
a solution.
