[libvirt-users] Libvirt management daemon issue
by Bilal Arif
robo@robo:~$ sudo /etc/init.d/libvirt-bin start
[sudo] password for robo:
* Starting libvirt management daemon libvirtd/usr/sbin/libvirtd:
/usr/local/lib/libvirt.so.0: version `LIBVIRT_PRIVATE_1.2.2' not found
(required by /usr/sbin/libvirtd)
Giving up waiting for /var/run/libvirt/libvirt-sock.
After installing libvirt from source a lot of Ubuntu user face this issue,
as i searched on internet about this, no solution works. this is mostly in
case of ubuntu users as mentioned in many posted threads. so please help
us as soon as possible. (this is only in case of installation libvirt from
source)

[libvirt-users] Is it possible to retrieve Non blocking socket writeable status of a unix channel device ?
by Jean-Pierre Ribeauville
Hi,
As using a blocking socket for a virtio device channel leads to be blocked if nobody has opened the corresponding /dev/virtio-ports within the Guest , I tried to use a non-blocking socket and
to check whether the socket is writeable via FD_ISSET().
I'm wondering why a virtio device channel is always seen as writeable by the Host even if nobody has opened the corresponding /dev/virtio-ports within the Guest ?
res= connect(sock, (struct sockaddr *) &server, sizeof(struct sockaddr_un));
if (res < 0) {
perror("connecting stream socket");
close(sock);
return(1);
}
else
tv.tv_sec = 15;
tv.tv_usec = 0;
FD_ZERO(&myset);
FD_SET(sock, &myset);
if (select(sock+1, NULL, &myset, NULL, &tv) > 0) {
len = sizeof(int);
getsockopt(sock, SOL_SOCKET, SO_ERROR, (void*)(&result), &len);
if (result) {
fprintf(stderr, "Error in connection() %d - %s\n", result, strerror(result));
return(1);
}
else
{
if(FD_ISSET(sock,&myset))
fprintf(stderr, "connection()is O.K. \n");
}
}
else {
fprintf(stderr, "Timeout or error() %d - %s\n", result, strerror(result));
return(1);
}
Did I misunderstood something ?
Thanks for help.

[libvirt-users] Retrieving datas sent by host within the Guest
by Jean-Pierre Ribeauville
Hi,
I' trying to read datas sent by my KVM host within the Guest.
Host send these datas trough a channel UNIX type , by using AF_UNIX socket stuff.
If i try to retrive the datas by using such type of thing in the Guest :
#define NAME "/dev/virtio-ports/agent"
sock = socket(AF_UNIX, SOCK_STREAM, 0);
12 if (sock < 0) {
13 perror("opening stream socket");
14 exit(1);
15 }
16 server.sun_family = AF_UNIX;
17 strcpy(server.sun_path, NAME);
18 if (bind(sock, (struct sockaddr *) &server, sizeof(struct sockaddr_un))) {
19 perror("binding stream socket");
20 exit(1);
21 }
I got ""binding stream socket Address already in use" when trying to bind the socket .
But If I use such kind of thing :
fd = open("/dev/virtio-ports/agent", O_RDWR | O_NONBLOCK);
ssize_t size = read(fd, &rcv_buffer, 100);
if(size >0) printf("Read length(%d) %s\n", size, rcv_buffer);
It works fine.
Is there any chance to be able to use socket stuff on Guest side or is there anything I misunderstand?
Thanks for help.

[libvirt-users] xen/libvirt freeze while attching network-device to vm´s
by max ustermann
Hi,
first sorry for the cross-posting, but i don ́t known exactly if my
problem belongs to xen or libvirt.
I have an VM-Host with Xen 4.6.0 und libvirt 1.2.19. The Job of the
Host is to resume in parallel 20 VM ́s (HVM WinXp) attach a
block-device to each VM , wait 60 Seconds, kill the VM and start from
beginning. For that, a python script create for each vm a thread and
each thread get a connection to the Libvirt-Daemon via
"libvirt.open(None)" and do the resume, attach and so on in a loop.
This Setup works fine, it do several thousand cycle without any
problems. If i complement this setup, so that each vm get , additonal
to the blockdevice an network-interface after resume, via
"attachDevice" call from the python-script, i observe that libvirtd/xen
freeze after 20 to 100 cycle. Their are no error-messages, no crash,
noting in "dmesg" or "xl dmesg".
When i attached to the libvirtd via gdb and do a "info thread", i get
the following:

so i see that thread 21 waits for a lock that holds by thread 21
from frame 4 i see, that the process want a lock for vm object:

further down in the bt i see in frame 14:

libxl/libxl_driver.c:3231 that vm-object 0x7f79140099c0 is the object
for that also a network-device should be attached. And from that i know
that there is a lock on the vm-object.
so i go up in the bt an see that libxlDomainAttachDeviceLive(libvirtd)
(frame14) calls libxlDomainAttachNetDevice(libvirtd) (frame13), that
calls libxl_device_nic_add(libxl/xen) (frame12)
from info frame for frame12 i see that he calls frame 0x7f792a92b5f0:

so further i see that libxl__ao_inprogress calls libxl__egc_cleanup and
that calls egc_run_callbacks, frame 9 info frame for frame 9 gives:

and list gives:

entry, aop_tmp) { 1409
LIBXL_TAILQ_REMOVE(&egc->aops_for_callback, aop, entry);
from here i see that egc_run_callbacks is at line 1405 "
CTX->event_hooks->event_occurs(CTX->event_hooks_user, ev);" , but i
have no idea what he is doing there and while it "hangs" here!?!
if i see it correctly, the systems freeze/hangs because it waits of the
release of the lock for the vm which actuall attach a network-device,
and the process of attaching the network-device didn ́t finished and
hold the lock. as i say at the geginning of my mail, if i only attach a
block-device to the vm`s every thing runs, and with additional
attaching a network-device after 20 to 100 resume , it freeze´s.
i am gratefull for any help,hints and tips for further debugging.
all the best

[libvirt-users] vm doesn't respond after live migration
by Fırat KÜÇÜK
Hi,
I migrate my VM with this command:
virsh migrate --live --domain my-domain --verbose --copy-storage-all
--desturi qemu+ssh://root@xxx.bulutkare.com/system
Migration completed successfully. But after migration VM doesn't respond.
I can see the login console. I typed root but no response.
What can be the problem?
Regards.

by Lentes, Bernd
Hi,
how can i shutdown a windows 7 vm although someone is logged on to that vm
via RemoteDesktop ?
Currently libvirt waits 5 min for the vm to shutdown and then switches it
off.

[libvirt-users] changeBegin() on python API
by Ramon Medeiros
Hi,
is changeBegin() working on python? I was trying to use the following
method:
if = conn.interfaceLookupByName("name")
if.undefine()
I saw that changeBegin() does not commit changes, but i can't use it.
