[libvirt-users] deadlock on connection loosing
by Александр
libvirtd will lock if for example kill programm which established connection,
only sigkill + restart helps., to reproduce:
virConnectPtr libvirt_connection = virConnectOpen("qemu:///system");
if(libvirt_connection == NULL)
{
std::cout<<"failed to connect to qemu:///system\n";
exit(-1);
}
exit(0);

[libvirt-users] Same credentials stored in auth.conf for many servers
by Maciej Gałkiewicz
Hello
According to client authentication in documentation (
http://libvirt.org/auth.html) it is possible to store credentials in
auth.conf file and make appropriate mappings to servers:
[auth-$SERVICE-$HOSTNAME]
credentials=$CREDENTIALS
Is it possible to use the same credentials for many servers without
explicitly describing it?
For example replacing:
[auth-libvirt-myhost1]
credentials=mycred
[auth-libvirt-myhost2]
credentials=mycred
with:
[auth-libvirt-myhost*]
credentials=mycred
or
[auth-libvirt-any]
credentials=mycred
regards

[libvirt-users] VMware distributed port groups..Supported?
by Morgan McLean
Hi,
I installed libvirt on CentOS 6 today, only to find I could create the
volume, create the VM, but could not assign the interface to a distributed
port group. I then downloaded the latest source, compiled, and it looks to
be the same...unless its under a command I'm not recognizing?
Does anybody have the great tip that is going to set me free? I hope?
Everything we use is on the vSwitches, as we run 60-80 VLAN's to each
cluster member.

Thanks,

[libvirt-users] qemu-img convert to "sparse" LV
by Edoardo Comar
Apologies as this is is not a specific libvirt question.
Is qemu-img convert compatible with thin-provisioned LVs as targets ?
I wanted to convert a file-based image to a LV image
where the file-based image has a capacity much larger than the actual data
it contains, so it has a small footprint on disk
(either a qcow2 or a raw, but sparse, image).
If I use qemu-img convert -O raw ... with a target LV sized to the full
capacity of the file-image, all is fine.
But if I try use an LV whose virtual size equals the capacity, but its
size is smaller (although more than enough for the data)
the LV is invariably corrupt.
If I try use a thin-provisioned LV pool, and a LV backed by that pool,
the LV resulting from qemu-img convert is not corrupt but it uses as much
space as the file-image capacity it came from.
This on both RHEL64 and Fedora18.

[libvirt-users] error : Failed to find user record for uid '32722'
by Tony Cebzanov
I'm trying to use the libvirt Python API to manage VirtualBox VMs on Mac
OS X 10.8.3. I'm running libvirt 1.0.6 via Homebrew. However, the
following trivial Python script:
import libvirt
conn = libvirt.open('vbox:///session')
gives me the following error:
libvirt: error : Failed to find user record for uid '32722': Success
Traceback (most recent call last):
File "ch3vm.py", line 3, in <module>
conn = libvirt.open('vbox:///session')
File "/usr/local/lib/python2.7/site-packages/libvirt.py", line 236,
in open
if ret is None:raise libvirtError('virConnectOpen() failed')
libvirt.libvirtError: Failed to find user record for uid '32722': Success
I have no idea where that uid 32722 is coming from -- it's not the uid
of my user account, any of my VirtualBox files, or anything else that
I'm aware of.
Anyone have any idea what's going on here?

[libvirt-users] virsh can create vHBA, but returen error msg "Node device not found"
by Dennis Chen
Hi,
I am using the libvirt 1.0.6 with the patch applied:
http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=371c155
The problem I encountered is, with virsh comand 'nodedev-create
/home/kvm/vHBA.xml', the vHBA can be generated as expected on the host,
but error msg will show in the virsh shell:
libvirt: Node Device Driver error : Node device not found
I try to find the reason with gdb, and found that the 'nodedev-create'
command will call virNetClientIOEventLoop() function of the remote
driver, in this function, code will wait on:
repoll:
ret = poll(fds, ARRAY_CARDINALITY(fds), timeout);
after about 50s, poll() returns, but the replied
msg->header.status=VIR_NET_ERROR.
I am not familiar with the rpc call in the remote driver, does anybody
here can give some clues?
BRs,
Dennis
