[libvirt-users] New vs old API usages
by Shahar Havivi
Hi,
Currently I am using the latest libvirt API listAllDomains() to probe for domains.
I may need to fall back to older API for old libvirt server such as: listDefinedDomains() and lookupByName()
instead of listAllDomains().
Is there any disadvantage to using listAllDomains instead of listAllDomains
or its the same results via different API?
Thank you,
Shahar.

[libvirt-users] Spice and client usb-redirection
by Dominique Ramaekers
Hi,
Is there anybody who got the usb-redirection working with remote-viewer on Windows?
If I install remote-viewer, the option to redirect usb devices is grayed out in the menu.
Greetings,
Dominique.

[libvirt-users] SOLVED: failed to connect to the hypervisor
by Ken D'Ambrosio
Ubuntu, for the loss. Turned out to be an apparmor issue; as I hadn't
touched the profiles, it must've been something else going on.
-Ken
------------------------- original issue ----------------------------
When I try, I get this:
root@kilo-VirtualBoxHost:~# virsh -c vbox:///session
error: failed to connect to the hypervisor
error: internal error: nsIEventQueue object is null
----------------------------------
The part that puzzles me is that it *used* to work, but no longer.
"virsh -V" shows me running libvirt 1.2.2, with VirtualBox enabled. I'm
running stock Ubuntu VirtualBox v. 4.3.10. I've rebooted; I've tried
running it as different users. Googling comes up with some
five-year-old Solaris patch discussions. My
/var/log/libvirt/libvirtd.log shows stuff like this:
2015-11-25 02:21:39.381+0000: 3893: error : virNetSocketReadWire:1454 :

Any pointers would be greatly appreciated.
Thanks!

Hi
I'm trying to get libvirt/virsh to work with Citrix XenServer...
I have recompiled libvirt from RHEL7 (1.2.8+patches) with xenapi support.. and it seems to be working:

Enter username for 192.168.60.82: root
Enter root's password for 192.168.60.82:

[libvirt-users] esx/vcenter: create a domain inside an folder
by Cyrill von Wattenwyl
Hello at all
Im trying to create a domain inside a folder:
Host: foo.tld
Datacenter: dc1
Cluster: cluster name1
Host: esx.tld
Folder: folder/subfolder (inside Cluster bar.tld)
URL: vpx://foo.tld/dc1/cluster%20name1/folder/subfolder/esx.tld
I tried nearly every combination since the documentation is not 100% clear about that, but libvirt allways creates the domains inside vpx://foo.tld/dc1/ and not goes "deeper".
My questions:
- Is it even possible to create domains inside of a folder inside a cluster? If yes, how?
- Could the whitespace in cluster name be a problem?
- The user im trying to create the vms does not have permissions to view/change things on level datacenter/cluster/main folder. it can only view things in the subfolder. Could this be the issue?
Thanks for your time and best regards,
Cyrill

[libvirt-users] removing PS/2 keyboard
by Tadas
Hello lists,
I wonder, is there a way to remove a PS/2 keyboard from a guest and
leave it only with USB bus one? Problem is that if i edit guest (via
virsh edit) and change keyboard bus from ps2 to usb, I end up with two
keyboards: ps2 and usb one.

[libvirt-users] libvirt prepare and start hooks not callled
by Sundar Nadathur
Hello,
I am using RHEL 7.1 and libvirt 1.2.8. My intention is to intercept the prepare and start hooks of libvirt during VM placement to inject a virtio PCI device into the VM's domain xml.
I placed a python script with execute permissions in /etc/libvirt/hooks/qemu. In there, I opened a log file to record the arguments received:
log.write("avfd called with args: %s\n" % sys.argv)
But all I get in the log file is:
avfd called with args: ['/etc/libvirt/hooks/qemu', 'vm1', 'started', 'begin', '-']
There are no prepare or start calls. Can somebody explain what it takes to fix this?
Cheers,
Sundar

[libvirt-users] Can't take live snapshot, not supported with this QEMU binary
by Tashi Lu
Hi all,
I was trying to take live snapshot of VMs, but I got the following error:
[root@localhost ~]# virsh snapshot-create-as 1 test desc --live
--memspec file=mem.bak,snapshot=external --diskspec
vda,snapshot=external,file=/root/root.bak.qcow2
error: Operation not supported: live disk snapshot not supported with
this QEMU binary
I upgraded my qemu-kvm 0.12.1 to qemu 1.2, the error still exists. Is
this really the problem of my qemu version or I did something wrong?
To what version should I upgrade? Thanks.
virsh version:
Compiled against library: libvirt 0.10.2
Using library: libvirt 0.10.2
Using API: QEMU 0.10.2
Running hypervisor: QEMU 0.12.1
